The ASSA ABLOY SMARTair i-gate Electronic Padlock (SNBBP3XI) is a battery-powered electronic padlock for gates, cages, closets and cabinets - the openings where an escutcheon, cylinder or wall reader cannot be fitted. It is a complete locking device: the reader, control unit, battery and electromechanical clutch are built into a sealed IP68 padlock with a stainless steel shackle, so it needs no drilling and no wiring.

This version reads HID iCLASS credentials and opens with Openow phone keys over Bluetooth LE - the Openow module is fitted at the factory. It runs in the SMARTair Update-on-Card + Openow tier: access rights travel on users' cards and refresh at an updater, phone keys are sent and revoked over the air, and the site needs no hubs (SMARTair System Information Guide).

Users open it by presenting a credential to the reader at the bottom of the padlock and turning it within about four seconds of the blue LED. It is managed in SMARTair TS1000 alongside the platform's escutcheons, knob cylinders and wall readers (SMARTair Product Overview), and it is one of four i-gate padlocks we list - see the item code family, or browse our other smart padlocks.

Estimated Dispatch
Usually ships in 3 business days.

Where the i-gate padlock fits
ASSA ABLOY designed the i-gate for external gates, closets and cabinets - any opening where it is impossible to install an escutcheon, cylinder or wall reader - and rates it for medium to high traffic (i-gate datasheet). On a door that can take one, a SMARTair i-max Update-on-Card + Openow escutcheon or Update-on-Card + Openow knob cylinder is the usual choice, and automated doors and barriers take a SMARTair i-Reader R4N Wide wall reader. The i-Reader reads MIFARE, so phone keys cross but iCLASS cards do not.

Key Features

• Complete battery-powered smart padlock for SMARTair - reader module, control unit, battery module and electromechanical clutch in one sealed unit, with no drilling and no wiring.
• Integrated HID iCLASS RFID reader for 13.56 MHz HID iCLASS cards and fobs; the reader wakes as a credential approaches and reads at 1-2 cm.
• Openow phone keys built in - the Openow module is fitted at the factory, so users open the padlock with a virtual key in the Openow app over Bluetooth LE.
• SMARTair Update-on-Card + Openow management - access rights ride on users' cards and refresh at an updater, while Openow keys update over the air, so there are no hubs to install.
• IP68 rated and resistant to extreme weather, provided the padlock hangs vertically with the shackle up and closed - see Outdoor Use and Weather Protection.
• Stainless steel shackle and a double security locking mechanism, protected by a black rubber cover.
• EN 15684 Class 6 durability; RCM and R-NZ marked.
• Up to 3,000 users and the last 1,200 events in non-volatile memory, with 30 time zones of five periods each and a 365-day calendar.
• Operating modes for standard, double-user and accessibility (ADA) opening, plus a high-traffic option for an unlimited number of users.
• One CR2 3V lithium battery - approx. 60,000 cycles or up to 2 years standby; low battery is signalled by the LED and reported to the software.
• No mechanical key override - on low battery the emergency opening is made with the SMARTair portable programmer on its 3-pin cable.
• Upgradeable firmware - ASSA ABLOY lists an upgrade from Update-on-Card + Openow to Wireless Online + Openow through the programming device (see System Integration).
• Suitable for medium to high traffic sites - see Suitable Uses.

Access Methods

How users open this padlock, and what it does not do. Chapter 03 compares every method side by side.

Method	Status	Notes
RFID Card / Fob (HID iCLASS)	Standard	HID iCLASS 13.56 MHz cards and fobs, encoded for your site with the SMARTair USB encoder; read at 1-2 cm. See how RFID credentials work
Openow Phone Key	Built in	Virtual key in the Openow app over Bluetooth LE, issued and revoked over the air; the site needs the Openow mobile access licence. See Bluetooth access explained
TESA SMARTair App	Not Available	Wireless systems only - see the Wireless Online version, SNZBP3XI
PIN Code	Not Available	No keypad - the i-gate opens by card or phone key only (no multi-authentication)
Mechanical Key Override	Not Available	No mechanical key override - on low battery the emergency opening is made with the portable programmer cable; see the no-key-override issue on padlocks
Fingerprint	Not Available	SMARTair uses cards, tags and phone keys, not biometrics

The Openow app is free for users on iOS and Android and phone keys are sent from TS1000. Browse other card and fob access, Bluetooth and app-enabled locks, or our smart padlocks.

What's In The Box

Not included: RFID credentials, the encoder, the portable programmer, the Openow licence and the TS1000 software licence, and the updater an Update-on-Card site uses. Openow phone keys are issued over the air.

Suitable Uses and Typical Installations

ASSA ABLOY built the i-gate for external gates, closets and cabinets - openings where an escutcheon, cylinder or wall reader cannot be fitted - at medium to high traffic (i-gate datasheet). It needs no drilling and no wiring, so it suits retrofit and temporary sites. Typical installations:

• Construction site security gates and temporary security fencing.
• Industrial infrastructure compounds and plant rooms.
• Utilities and energy facilities, including water infrastructure.
• Data centre equipment cages.
• Medical, hospital and pharmaceutical storage cabinets.
• Commercial plant rooms and building service cupboards.
• University and campus maintenance areas.
• Remote infrastructure and storage areas that need credential-based padlock access.
• Sites where permissions change periodically and hubs are not wanted - users collect changes when they present their card at an updater (Information Guide).
• Mixed SMARTair sites - the padlock sits alongside escutcheons, knob cylinders and wall readers in the same TS1000 system, and tiers can be combined on one site (system architecture).
• External gates exposed to the weather - see our External Gate Exposed to Rain category and Outdoor Use and Weather Protection.

Not suitable for

• Doors that can take an escutcheon, knob cylinder or wall reader - use a SMARTair i-max Update-on-Card + Openow escutcheon, Update-on-Card + Openow knob cylinder or i-Reader R4N Wide wall reader instead.
• Sites that need PIN entry or two-factor opening - the i-gate has no keypad.
• Sites that want a mechanical key backup - there is no key override, so plan for the portable programmer.
• Hanging the padlock sideways, or leaving it open outdoors - the weather sealing only holds when it hangs vertically with the shackle up and closed.
• Sites that need changes to reach the padlock straight away - choose the Wireless Online + Openow version, SNZBP3XI.

Outdoor Use and Weather Protection

The SMARTair i-gate electronic padlock is designed for outdoor environments and carries an IP68 rating; ASSA ABLOY describes it as resistant to real extreme weather conditions, from -20 to +70 degrees C and up to 85 percent humidity (i-gate datasheet). The sealed electronic module and the protective rubber cover keep dust and moisture away from the internal components, which suits gates, infrastructure enclosures, cages and external equipment storage.

Weatherproof use of the i-gate: hang it vertically with the shackle up, and keep the shackle closed.

Keep the weather sealing intact

• Install the padlock vertically with the shackle facing upwards.
• Weather protection holds only while the shackle is fully closed - do not leave the padlock open outdoors.
• Push the shackle in firmly when you close it - that is what seals the padlock correctly.

Following these guidelines keeps the rated protection and long-term reliability outdoors. See IP ratings explained, IP ratings for outdoor padlocks and what coastal air does to electronics.

Item Code Family - SMARTair i-gate Electronic Padlocks

The four i-gate padlocks we list share the same IP68 padlock and differ by management tier (set by the factory-fitted RF module) and reader technology. Choose the tier for how you want to run the site, and the reader to match the cards it already uses.

What's the difference between MIFARE and HID iCLASS?
Both are secure 13.56 MHz RFID credential technologies used in commercial access control, and each i-gate reader is set to one of them. MIFARE is widely used in access control, universities, transport cards and multi-application credential systems. HID iCLASS is HID's own credential platform, typically used in enterprise security systems and facilities that already run HID cards. The reader must match the credential technology of the site's existing cards or fobs - if you are not sure which your site uses, send us a sample card and we will check it before you order. Openow phone keys work on either version.

System Integration

• Managed by SMARTair TS1000 - Windows client/server software with its own database, which sets up the installation and initialises devices with the portable programmer; Web Manager then gives browser-based management of users, doors, time zones, access rights and events (Product Overview).
• Update-on-Card management: access rights travel on users' credentials, which carry access-plan updates around the lock network, and events are collected automatically when users revalidate their credential at an updater (Information Guide).
• Openow on top: access-plan changes over the air and automated event history collection - the facility manager can send, revoke and update virtual keys from anywhere through TS1000, and collect door history and trigger email alerts remotely via users' Openow app (Information Guide).
• Equipment for this tier: the TS1000 software licence, a card encoder, the portable programmer (or PC-TO-LOCK) and an updater, plus the Openow licence for phone keys (devices you need; management devices).
• The padlock's calendar needs updating once a year - done manually on Update-on-Card sites - and daylight saving changes are automatic (i-gate datasheet).
• Upgrade path: ASSA ABLOY lists a firmware upgrade from Update-on-Card + Openow to Wireless Online + Openow, carried out with the programming device (i-gate datasheet). The same sheet describes the Wireless + Openow module as a factory-fitted part, so confirm with us what the upgrade needs for your padlock before planning on it.
• Openow keys reach phones through TS1000's cloud connection over HTTPS 443 (system architecture).
• Works alongside the rest of SMARTair. Tier- and credential-matched devices for the same site are the Update-on-Card + Openow i-max escutcheons (SNBB43SL1S008DI, SNBB43SL2V648DI, SNBB47SL1S008DI) and knob cylinders (SNBB43X030E10MI black, SNBW43X030E10MI white) - all HID iCLASS with Openow. The i-Reader R4N Slim S4BR2Slim1 and i-Reader R4N Wide S4BR2Wide1 wall readers read MIFARE, so phone keys cross but this padlock's iCLASS cards do not.

No hubs on this tier
Update-on-Card + Openow needs no hubs: changes reach the padlock on users' updated cards and through Openow phone keys, and events come back when users revalidate at an updater or through their Openow app (Information Guide). If you want live monitoring and instant changes instead, the Wireless Online + Openow version is SNZBP3XI.

Update-on-Card + Openow or Wireless Online + Openow?

The i-gate padlocks we list come in two SMARTair management tiers. The padlock and reader are the same; the factory-fitted RF module (Openow, or Wireless + Openow) sets the tier, and the tier decides how changes reach the padlock and how events come back. This padlock's column is in bold.

SMARTair also runs Standalone and Update-on-Card tiers without phone keys; ASSA ABLOY notes that an i-gate built without the Openow module cannot be upgraded to an Openow tier, and the four we list all carry one (i-gate datasheet). Tiers can be combined on one site (Product Overview), and automatic cancellation of lost cards and activation and expiry dates are available on every tier except Standalone (feature comparison). For a full explanation see the SMARTair System Information Guide or the SMARTair Wireless Access Control Product Overview.

Power Supply and Battery System

• Battery-powered electronic padlock - one CR2 3V lithium battery (i-gate datasheet).
• Battery life: approx. 60,000 cycles, depending on the reading technology, or up to 2 years standby depending on cycles per day.
• Easy battery change: users and events sit in non-volatile memory, and the clock and calendar are held for 5 minutes without a battery.
• Low battery is signalled by the warning LED, and battery status is reported with every event, or once a day when there are none.
• No mechanical key override - emergency opening is performed with the SMARTair programming device.

No key override - plan for a low battery
The i-gate has no mechanical key override. If the battery runs too low to open the padlock, the emergency opening is made with the SMARTair portable programmer connected by its 3-pin cable - ASSA ABLOY lists emergency openings on low battery as one of that connection's jobs (i-gate datasheet). Openow phone keys and the card reader run on the padlock's own battery too, so neither is a fallback. Change the CR2 when the low-battery warning shows, keep the programmer where your site manager can reach it, and see the no-key-override issue on padlocks.

Real-world battery life depends on traffic and conditions - the truth about battery life and power and battery FAQs.

How to Open the i-gate Padlock

1. Present your card or tag to the reader at the bottom of the padlock - it wakes as the credential approaches.
2. The blue LED lights to confirm access: turn the padlock to open it within approximately 4 seconds.
3. A red LED means the credential is not authorised.
4. With a phone key, open the Openow app, press the padlock and hold the phone to the lock (Openow User Guide; February 2019, so screens may differ from today's app).
5. To lock it, push the shackle in firmly - that is what seals the padlock correctly.

Full Specifications

Technical data from the i-gate datasheet, which covers every i-gate reader option; battery cycles vary with the reading technology.

Dimensions

Manufacturer dimensional drawing for the SMARTair i-gate padlock. With the protective cover the padlock measures 67 x 51 mm and 106 mm high below the shackle; the stainless steel shackle is 9 mm in diameter, with 31.8 mm between its legs and 56 mm of clear height above the cover. The padlock itself, cover off, is 56 mm wide with a 35 mm reader knob. Check the shackle fits the hasp or chain before ordering (i-gate datasheet).

Related SMARTair Products and Guides

• Other i-gate padlocks. This is the Update-on-Card + Openow (iCLASS) padlock. For real-time control choose the Wireless Online + Openow (iCLASS) version; MIFARE equivalents are the UOC + Openow (MIFARE) and Wireless + Openow (MIFARE) padlocks. See the full range in the item code family.
• Other SMARTair formats. For doors that can take an escutcheon or cylinder, use a SMARTair i-max Update-on-Card + Openow escutcheon or Update-on-Card + Openow knob cylinder; for automated doors, turnstiles and barriers use a SMARTair i-Reader R4N Wide wall reader. Tier- and credential-matched devices for the same site are the Update-on-Card + Openow i-max escutcheons (SNBB43SL1S008DI, SNBB43SL2V648DI, SNBB47SL1S008DI) and knob cylinders (SNBB43X030E10MI black, SNBW43X030E10MI white) - all HID iCLASS with Openow. The i-Reader R4N Slim S4BR2Slim1 and i-Reader R4N Wide S4BR2Wide1 wall readers read MIFARE, so phone keys cross but this padlock's iCLASS cards do not.
• Managing and commissioning. Credentials are written with the SMARTair USB encoder, the padlock is initialised with the SMARTair portable programmer and Openow is enabled with an Openow mobile access licence. An Update-on-Card site also needs an updater, which we quote with the job.

Frequently Asked Questions

MIFARE or HID iCLASS - which i-gate do I need?
The one that matches the cards your site already uses. This listing reads HID iCLASS; the MIFARE version is SNBBP2XI. Openow phone keys work on both. Not sure what your cards are? Send us a sample and we will check it.

Does this padlock need hubs or a network connection?
No. On Update-on-Card + Openow, changes reach the padlock on users' updated cards and through Openow phone keys, so no hubs are needed (Information Guide). For live monitoring and instant changes, choose the Wireless Online + Openow version.

What happens if the battery runs out?
The padlock warns first with its low-battery LED and reports battery status to the software. There is no key override, so on low battery the emergency opening is made with the SMARTair portable programmer connected by its 3-pin cable (i-gate datasheet). Phone keys need battery power too, so change the CR2 when the warning shows.

Can it be left outdoors?
Yes - it is IP68 rated for -20 to +70 degrees C and up to 85 percent humidity. The weather protection only holds when the padlock hangs vertically with the shackle up and the shackle is closed, so never leave it open, and push the shackle in firmly when you lock it. See Outdoor Use and Weather Protection.

Can users open it with their phone?
Yes. Openow is built in, so users open the padlock with a virtual key in the free Openow app over Bluetooth LE; the site needs the Openow mobile access licence in TS1000.

Additional Information

• Dispatch and planning. This padlock usually ships in 3 business days. Order the system items at the same time - credentials, the encoder, the portable programmer and the Openow licence - so the padlock can be commissioned when it arrives.
• Plan the updater. On Update-on-Card, users pick up changes when they present their credential at an updater, so place one where users pass regularly (devices you need); Openow users also receive changes over the air.
• Weather sealing depends on how it hangs. IP68 protection holds only with the padlock vertical, shackle up and closed - an open padlock left outdoors is not sealed. See IP ratings for outdoor padlocks.
• No key override. Keep the portable programmer where your site manager can reach it, change the CR2 when the warning shows, and swap it promptly - the clock and calendar are held for 5 minutes without a battery. See the no-key-override issue.
• Data and support. TS1000 keeps the site database on your own server, and Openow keys reach phones through TS1000's cloud connection over HTTPS 443 (Product Overview). For where access platforms keep data, see platforms hosted outside China.
