The ASSA ABLOY SMARTair Standalone Wall Reader (SNAR3KUSSB) - catalogued by ASSA ABLOY as the SMARTair wall reader "PIN/Prox" - is a wired access control reader with a PIN keypad and an HID iCLASS card reader, for electric locks, automatic doors, gates and other controlled access points.
Users open with a code, an RFID credential or a combination of both, depending on how the reader is set up. In Standalone SMARTair mode the reader keeps its users and permissions itself and releases the connected electric strike or magnetic lock through its relay board - there is no network or software to run, and the site is set up with SMARTair programming cards (Product Overview).
It suits commercial buildings, industrial facilities, education campuses and other sites that want credential-based access control without network infrastructure. As the site grows, the reader can be upgraded to Update-on-Card and then Wireless Online by adding an RF module and a firmware upgrade (wall reader datasheet); the Wireless Online version with Openow is the SNZR3KUSSB. For the whole platform, see the SMARTair Wireless Access Control Overview.

What the wall reader needs to work
The reader and its relay board release a separate electromechanical device - an electric strike, electromagnetic lock or escape-route device - and cabling is needed (wall reader datasheet). Relay 1 commands that lock, which is not included, and the reader draws its 12-24 VAC/VDC power through the relay board from a supply you provide. On a door without electric locking, a battery-powered SMARTair i-max Standalone escutcheon or Standalone knob cylinder locks the door by itself.

Suitable Uses
ASSA ABLOY designed SMARTair wall readers for automated doors, turnstiles, barriers, lifts and any access whose locking or blocking element is automated (wall reader datasheet). Typical installations:
- Doors with an electric strike or electromagnetic lock, and automatic doors.
- Gates, turnstiles, barriers and lifts - any opening whose locking or blocking element is electrically operated.
- Escape routes, where the relay board drives the escape-route device.
- Commercial buildings, industrial facilities and education campuses.
- High-traffic openings - ASSA ABLOY rates the reader for high traffic volume.
- Sites that want PIN, card or card + PIN access without network infrastructure.
- Mixed SMARTair sites - the reader sits alongside escutcheons, knob cylinders and i-gate padlocks, and management tiers can be combined on one site (system architecture).
Not suitable for
- Doors without electric locking - a SMARTair i-max Standalone escutcheon or Standalone knob cylinder locks the door by itself on battery power.
- Sites running MIFARE cards - this listing is the HID iCLASS version; for MIFARE, see the seven i-Reader R4N readers, such as the S4ZR2DSlim and S4ZR2PWide (Wireless Online + Openow) and the S4BR2Slim1 and S4BR2Wide1 (Update-on-Card + Openow).
- Openings without a 12-24 VAC/VDC supply and cabling to the relay board.
- Mounting the relay board outside - the IP55 rating is for the wall reader.
- Sites that want central management, live audit collection, or phone keys from day one without adding the Openow module - choose the Wireless Online + Openow SNZR3KUSSB.

SMARTair Wall Reader Comparison
The two SMARTair keypad wall readers we list share the MURAL reader, the HID iCLASS card reader and the relay board, and differ by management tier. This product's column is in bold.
MIFARE vs HID iCLASS - What's the Difference?
Both are secure 13.56 MHz RFID credential technologies used in commercial access control. MIFARE is widely used in commercial access systems, universities, transport cards and multi-application credentials. HID iCLASS is HID's own credential platform, used in many enterprise security systems. The reader technology must match the credentials used in the building's access control system - the i-Reader R4N readers read MIFARE, and the MURAL keypad readers we list are the HID iCLASS versions. If you're not sure which your site uses, send us a sample card and we will check it before you order.

System Integration
- Standalone management: the reader holds its own users, PIN codes and permissions, and the site is set up with SMARTair programming cards rather than software (devices you need).
- On Standalone, lost cards are cancelled by hand and credentials can't carry activation or expiry dates - both come with the managed tiers (feature comparison).
- The yearly calendar is updated once a year with the portable programmer, and daylight saving changes are automatic.
- Emergency opening and service: a jack connection takes the portable programmer and emergency kit (wall reader datasheet).
- Upgrade path: Standalone, then Update-on-Card, then Wireless Online - by adding an RF module and a firmware upgrade; the R4 circuit is required (wall reader datasheet).
- Works alongside the rest of SMARTair. On a Standalone site the reader sits alongside the SMARTair Standalone knob cylinders (SNAB43X030E10MI black, SNAW43X030E10MI white) and i-max Standalone escutcheons (SNAB43SL2V648DI, SNAB43SL2V908DI, SNAB47SL2V648DI, SNAB47SL2V908DI) - all HID iCLASS, so the same cards open every door, and all are set up with programming cards.
Standalone - when it fits
A Standalone reader is set up and changed at the door, so it suits a small number of openings with a stable user list. Once the site wants central management, automatic cancellation of lost cards, audit collection or phone keys, the reader can be upgraded, or you can start with the Wireless Online + Openow SNZR3KUSSB. See the SMARTair System Information Guide for how the tiers compare.

See the SMARTair System Information Guide for how the tiers compare.
How the SMARTair Standalone Reader is Used
In Standalone mode the reader stores user credentials and PIN codes itself. When a valid credential or PIN is presented, it switches its relay output to unlock the connected door or access control device.
- Install the reader on the wall near the door or gate, with the relay board on the secure side.
- Connect relay 1 on the relay board to the electric strike, electromagnetic lock or door automation controller.
- Program the authorised PIN codes and RFID credentials using SMARTair programming cards.
- Users gain access by presenting a credential, entering a PIN, or both, depending on how the reader is set up.
Standalone readers suit locations that need a simple, reliable electronic access solution without connecting to a centralised access control network.
Full Specifications
The MURAL reader, relay board, power, environmental and certification data is shared across the MURAL wall reader range and comes from the wall reader datasheet, which documents the version without a keypad; the keypad and PIN details are specific to this keypad version.

Additional Information
- Dispatch and planning. This reader usually ships in 3 business days. Order the rest of the job at the same time - the strike or lock, the power supply, programming cards and credentials - so it can be commissioned in one visit.
- Plan the power and cabling. The reader runs from a 12-24 VAC/VDC supply through its relay board, and the relay switches the lock without powering it, so the strike or magnetic lock needs its own supply. Choose a fail-safe or fail-secure locking device to suit the opening. It is a job for an experienced access control installer - see advice and installation.
- Keep the programming cards safe. A Standalone reader is set up and changed with SMARTair programming cards, and lost cards are cancelled by hand on this tier (feature comparison) - store the cards securely and record who holds which credential.
- Match the credential first. This listing reads HID iCLASS; the MIFARE equivalents are the i-Reader R4N readers. If the site already has cards, send us a sample before ordering.
- Data and support. On Standalone, users, PINs and events are held in the reader itself. When the site moves to a managed tier, TS1000 keeps the site database on your own server (Product Overview). For where access platforms keep data, see platforms hosted outside China.

What do the two relays do?
Relay 1 commands the electromechanical lock, which is not included, and relay 2 can be used for other purposes - its function is set on the board's dip switch, or in the management software on a managed site (wall reader datasheet). A smaller single-relay board and an 8-output lift board are available as spare parts.

Fail-safe or fail-secure - which lock should I use?
It depends on the opening. A fail-safe lock releases when power is lost and a fail-secure lock stays locked, so the choice follows the opening's exit and security needs. We will help you pick the strike or magnetic lock when we quote.

Can it use a door sensor and an exit button?
Yes. The relay board has inputs for a door position sensor - so intrusion or a door left open is reported - and a request-to-exit push button, plus a tamper switch in the board itself. The sensor and button are not included (wall reader datasheet).

Where does the relay board go?
On the secure side of the opening, away from the weather - the IP55 rating covers the wall reader. It comes in a box for surface mounting, and the board can also go on a DIN rail (enclosure not included; the tamper switch must then be overridden or added separately) (wall reader datasheet).

What happens in a power cut?
The reader and relay board stop until power returns, while users and events stay in non-volatile memory and the clock is held for 48 hours by an internal backup battery (wall reader datasheet). What the door does depends on the lock - see what actually happens in a power outage.

Who should install it?
An experienced access control installer - it is a wired job with a power supply, a relay board and an electric lock to set up, and the reader then has to be initialised and commissioned in SMARTair. See when DIY makes sense, our advice and installation and professional installation.

The IP rating covers water and dust, not salt air, and ASSA ABLOY doesn't quote a salt spray figure for the reader. Its warranty excludes corrosion, so on the coast choose a sheltered position and check the reader regularly - see coastal environments and what coastal Queensland does to locks.

Software and System Management
Does a Standalone reader need software?
No - it is set up with programming cards (Product Overview). TS1000 and Web Manager come in when the site moves to Update-on-Card or Wireless Online (software).

Can one site mix tiers and device types?
Yes. SMARTair management systems can be combined on one site (system architecture), so a building can run different tiers where they suit. On a Standalone site the reader sits alongside the SMARTair Standalone knob cylinders (SNAB43X030E10MI black, SNAW43X030E10MI white) and i-max Standalone escutcheons (SNAB43SL2V648DI, SNAB43SL2V908DI, SNAB47SL2V648DI, SNAB47SL2V908DI) - all HID iCLASS, so the same cards open every door, and all are set up with programming cards.

How many users and events does it hold?
1,500 users and 600 events in normal mode, or unlimited users filtered into 48 groups with 1,000 events on a high-traffic door (wall reader datasheet).

Where is the data kept?
On Standalone, users, PINs and events are held in the reader itself; if the site moves to a managed tier, TS1000 keeps the site database on your own server (Product Overview). For how access platforms compare on data hosting, see platforms hosted outside China and security and data sovereignty.
