The ASSA ABLOY SMARTair i-MAX R4N Sliding Door Keypad Escutcheon Kit (S4B46SL2V6480I-SB) is a matched SMARTair access control kit for timber sliding doors: an i-MAX R4N electronic escutcheon with an integrated keypad, MIFARE card reader and DDA lever, supplied with the Lockwood Selector 3773E self-latching sliding door mortice lock. The escutcheon runs on batteries, so the door needs no cabling.

This listing is the keypad kit on the Update-on-Card tier (ASSA ABLOY code S4CB46SL2V6480I-SB): users open the door by card, PIN or card plus PIN, and a key in a Lockwood oval cylinder overrides it, with the 3773E's latch hold-back letting you turn the key one-handed. If you do not need PIN entry, the card-only version of this kit (S4B42SL2V6480I-SB) costs less. Browse other PIN code smart locks and smart locks with a backup key.

Access is managed in ASSA ABLOY's TS1000 software: rights ride on each user's card and refresh at an online updater, so the door needs no network. ASSA ABLOY also makes this kit with Openow phone keys and on the Wireless Online tier - page 7 of the 3773E sliding door brochure lists the codes, and our door types guide covers sliding doors more broadly.

Estimated Dispatch
Usually ships in 3 business days.

Commercial Wireless Access Control
The kit is built for commercial and institutional sliding doors - offices, healthcare and aged care, schools and apartment common areas. The escutcheon is rated to EN 1906 Grade 4 category of use and the 3773E to AS 4145.2 durability level D8. SMARTair is one of the commercial access-control brands we support.

Disability Compliance (DDA)

• Supplied with a DDA lever handle, and ASSA ABLOY states the 3773E sliding door solution complies with AS 1428.1 for accessibility (3773E brochure, page 3).
• Accessibility is still assessed on the complete doorset - handle heights, circulation space and door operating force on the sliding leaf all count.
• For accessible housing and NDIS projects, see our DDA and accessibility chapter and the NDIS and DDA housing guide.

Fire Doors

• The SMARTair i-max escutcheon is EN 1634 fire tested - a European test of the escutcheon on a test doorset.
• The 3773E brochure gives no fire rating for the sliding door lock, and we do not quote an Australian fire resistance level (FRL) for this kit.
• Treat this as a kit for non-fire-rated sliding doors unless the doorset manufacturer certifies it. Our guides to fire door core types and fire door types and certification explain what to check.

Key Features

• A matched kit: SMARTair i-MAX R4N escutcheon plus the Lockwood 3773E sliding door mortice it is made to drive.
• Integrated MIFARE reader for 13.56 MHz cards and fobs - see how RFID credentials work.
• Integrated keypad: open by card, by PIN code, or by card plus PIN for two-factor doors.
• Update-on-Card access control: rights travel on the user's card and refresh at an online updater, so the door needs no cabling or network.
• Mechanical key override through a Lockwood oval cylinder (supplied separately), with latch hold-back for one-handed operation.
• Self-latching: the 3773E latch engages automatically as the sliding door closes.
• 3773E rated to AS 4145.2-2008 security level S7 (S8 with door furniture and an anti-drill cylinder), durability D8 and corrosion C6.
• DDA lever handle; the 3773E solution complies with AS 1428.1.
• Battery powered by 3 x AAA LR03 alkaline cells - approx. 75,000 to 105,000 openings or up to 2 years.
• Approx. 3,000 users and an audit trail of approx. 1,200 events stored at the door.

Simple installation on existing sliding doors
ASSA ABLOY says the wireless escutcheons need only minor changes to an existing mechanical door preparation, and a retrofit fixing kit (3773ERFKITSS) suits doors that had the Lockwood 3573 sliding door strike (3773E brochure, pages 4 and 7).

Access Method	Availability	Notes
RFID Card / Fob	Standard	MIFARE 13.56 MHz credentials, encoded with the SMARTair USB encoder.
PIN Code	Standard	Integrated keypad on the outside escutcheon.
Card + PIN	Standard	Two-factor opening where a door needs both credentials.
Mechanical Key Override	Standard	Lockwood oval cylinder in the 3773E (cylinder supplied separately); latch hold-back for one-handed use.
Openow Phone Key	Not On This Tier	Openow is built into the S4BB and S4ZB kit codes - see Available System Variants.
Fingerprint	Not Available	SMARTair uses cards, PIN and phone keys, not biometrics.
Onboard Wi-Fi	Not Available	Real-time control is by SMARTair hubs on the Wireless Online tier, not Wi-Fi.

Openow Phone Keys - Not Built Into This Tier

This listing is the Update-on-Card kit, so it opens on cards and PIN and does not include Openow. ASSA ABLOY makes the same kit with Openow built in on the Update-on-Card + Openow tier (S4BB codes) and the Wireless Online + Openow tier (S4ZB codes), where users carry a virtual key in the Openow app and a site adds the Openow mobile access licence. Ask us if phone keys matter on your project - see Available System Variants below.

What's In The Box

• SMARTair i-MAX R4N outside escutcheon with integrated MIFARE reader and keypad
• Inside escutcheon with battery compartment
• DDA lever handle set
• Lockwood Selector 3773E self-latching sliding door mortice lock, timber door fixing
• Battery pack for the escutcheon
• Mounting hardware, fixings and assembly components
• Installation documentation for the escutcheon and the 3773E

Not in the box
The Lockwood oval cylinder for the key override is not included, nor are credentials, the USB encoder, the portable programmer or the TS1000 software licence. Aluminium doors need the 3773EAFKITSS fixing kit, ordered separately. The 3773E itself is not sold on its own - it comes only in these matched kits.

Suitable Uses

• Commercial and institutional timber sliding doors that need managed access on cards and PIN.
• Healthcare and aged care wards, utility rooms and corridors where one-handed, accessible operation matters.
• Education campuses - classrooms, labs and stores on sliding openings.
• Apartment and mixed-use common areas on sliding doors.
• Sites standardising on SMARTair MIFARE credentials, alongside the i-Reader R4N Slim for Update-on-Card and the i-gate MIFARE padlock.

Not suitable for

• Hinged doors - see the SMARTair i-max hinged escutcheons (these read HID iCLASS, not MIFARE).
• Fire-rated sliding doors, unless the doorset manufacturer certifies the kit.
• Aluminium sliding doors without the 3773EAFKITSS fixing kit.
• Sites that need phone keys, live door status, remote opening or lockdown - these need the Openow or Wireless Online kit codes.
• Doors where the outside face is exposed to weather - ASSA ABLOY lists its IP56 exterior version without a keypad.

Available Finish Options

• 
  Black
  (This Product)
  STK S4B46SL2V6480I-SB

Finish selection does not affect functionality, compliance, or performance.

The kit is supplied with the black reader and the DDA lever handle; the 3773E has a stainless steel faceplate as standard.

Available System Variants

ASSA ABLOY lists six SMARTair i-MAX R4N codes for the 3773E - card-only and keypad, on three management tiers - all black, MIFARE, DDA and key override, with 3773E timber fixing (3773E brochure, page 7). We list the two Update-on-Card kits; the Openow and Wireless Online codes are ordered in on request.

Tiers are compared on page 4 of the SMARTair Product Overview. The Wireless Online tier talks to the server through SMARTair hubs - see our guide to what a gateway does. Emergency lockdown (TS1000 Lockdown Upgrade) is a Wireless Online feature only.

SMARTair Platform

• Managed in TS1000 - ASSA ABLOY's Windows client/server software - with the browser-based Web Manager for day-to-day administration; Web Manager needs a public IP address on the server (Product Overview, page 6).
• An Update-on-Card site needs a software licence, the USB encoder for cards, the portable programmer (or PC-TO-LOCK) for the doors, and online updaters where users refresh their cards (Product Overview, page 3).
• Lost or stolen cards are cancelled automatically, and users can be given activation and expiry dates (Product Overview, page 4).
• SMARTair tiers can be combined on one site and upgraded as it grows (Product Overview, page 5); our platform chapter compares SMARTair with other ecosystems.
• Sales, warranty and technical support are handled in Australia by ASSA ABLOY.

Lock Information - Lockwood 3773E Sliding Door Mortice Lock

The Lockwood Selector 3773E sliding door mortice lock.

• Australian designed and assembled self-latching sliding door mortice; the latch engages automatically as the door closes.
• 60 mm backset - see our backset measuring guide.
• Stainless steel self-latching bolt with an auxiliary stainless deadlatching bolt; high-purity zinc alloy case; stainless steel faceplate as standard.
• Latch hold-back for one-handed operation during key override (brochure, page 3).
• Takes a standard Lockwood oval brass cylinder (bump-resistant 5-pin) with an X7 or V cam - supplied separately.
• AS 4145.2-2008 security level S7 (S8 with door furniture and an anti-drill cylinder), durability D8 and corrosion C6 (168 hours) (brochure, page 5).
• Designed to integrate with ASSA ABLOY Aperio, SMARTair and Integral escutcheons; supplied here with timber door fixing.
• Fixing kits: 3773EAFKITSS converts the fixing for aluminium doors, and 3773ERFKITSS suits retrofits where the door had the Lockwood 3573 sliding door strike.

Power Supply and Battery System

• Powered by 3 x AAA LR03 alkaline batteries in the inside escutcheon.
• Approx. 75,000 to 105,000 openings or up to 2 years, whichever comes first.
• The escutcheon warns of low battery before the batteries run out - change all three cells together when it does.
• Battery life is shaped by traffic and environment - see what really affects battery life.

Key override when the batteries are flat
Fit a Lockwood oval cylinder to the 3773E and a key opens the door if the escutcheon batteries run flat; the latch hold-back lets you turn the key and slide the door one-handed. Read about key override when the battery dies.

Frequently Asked Questions

Is the mortice lock included?
Yes. The kit includes the Lockwood Selector 3773E sliding door mortice with timber fixing. The oval key cylinder is not included, and the 3773E is not sold separately.

Can users open it with a phone?
Not on this listing. It is the Update-on-Card kit, which opens on cards and PIN. ASSA ABLOY makes the same kit with Openow phone keys (S4BB and S4ZB codes) - ask us to order one in.

Will the same cards open my hinged SMARTair doors?
Only if those doors read MIFARE. This kit reads MIFARE; the SMARTair i-max hinged escutcheons we list read HID iCLASS, so cards will not cross between them. The i-Reader R4N Slim for Update-on-Card and the i-gate MIFARE padlock share this kit's credential technology.

What happens if the batteries go flat?
The escutcheon warns of low battery first. If the batteries do run flat, a key in the Lockwood oval cylinder opens the door, and the latch hold-back lets you do it one-handed - see key override when the battery dies.

Can it go on a fire-rated sliding door?
Not on our advice. The escutcheon is EN 1634 fire tested, but the 3773E brochure gives no fire rating for the sliding lock. Treat the kit as for non-fire-rated doors unless the doorset manufacturer certifies it - see fire door types and certification.

Additional Information

• Which tier this listing is. Our store code S4B46SL2V6480I-SB matches ASSA ABLOY's Update-on-Card code S4CB46SL2V6480I-SB. If your site runs Openow or Wireless Online, order the matching S4BB or S4ZB code instead, so every door speaks to the same system.
• Timber or aluminium. The kit comes with timber fixing. Aluminium doors need the 3773EAFKITSS fixing kit, and doors that had a Lockwood 3573 sliding strike can use the 3773ERFKITSS retrofit kit (brochure, page 7).
• Credentials. Plan on MIFARE cards or fobs encoded for your site with the USB encoder. If the building already runs iCLASS SMARTair doors, those cards will not open this kit.
• Installation. Sliding door preparation and SMARTair commissioning go together. The dimension drawing has no scale statement, so check figures against the hardware. Our advice and installation team and site survey service can take this on.
• Coastal sites. The 3773E is rated to corrosion level C6 (168 hours), but batteries and electronics still suffer in salt air - see electronic locks in coastal conditions.
