SECO-LARM SK-1323-BPQ Keypad and 125kHz Proximity Reader Technical Details
The SECO-LARM SK-1323-BPQ ENFORCER is a black, weatherproof stand-alone digital access keypad with a built-in 125kHz proximity reader. It is designed for gates, pedestrian doors, commercial entrances, parking applications, and other access-control systems that require local code or proximity credential management without a separate basic keypad controller.
The SK-1323-BPQ combines keypad access, proximity credential reading, two programmable Form C relay outputs, two request-to-exit inputs, a door sensor input, EEPROM memory, and optical tamper protection in an IP65 aluminum housing.
Built-In 125kHz Proximity Reader
The SK-1323-BPQ includes a 125kHz proximity reader with a published sensing distance of approximately 2 in (50 mm). Compatible proximity credentials are presented directly in front of the keypad for access.
SECO-LARM lists PR-K1K1-AQ proximity key fobs and PR-K1S1-A proximity cards as accessories for this keypad family. Do not assume that unrelated 125kHz credentials will work solely because they use the same nominal frequency. Confirm credential format and compatibility before ordering cards or fobs.
Card, Code, or Card Plus Code Access
Output 1 on the SK-1323-BPQ can be configured for three access modes:
- User card only
- User card or user code
- User card and user code
The card-plus-code option provides two credential steps for applications where a proximity credential by itself is not sufficient. Each Output 1 user can be programmed with a code, a card, or both depending on the selected access mode.
Output 2 users may be assigned a user code or a user card. Output 2 can also be configured for doorbell operation instead of normal user access operation.
Up to 1,010 User Codes
SECO-LARM specifies support for up to 1,010 user codes. User codes are programmable from 2 to 6 digits, and the selected code length applies to the keypad's programmed user codes.
EEPROM memory protects programmed information during a loss of operating power.

Dual Form C Relay Outputs
The SK-1323-BPQ provides two Form C relay outputs with Normally Open, Normally Closed, and Common contacts. Each relay is rated at 1A at 30VDC.
Both outputs can be programmed for a 1-99 second activation period or toggle operation. The relay rating must be checked against the connected equipment. Do not assume the keypad can directly power every electric strike, magnetic lock, gate accessory, or other electrical load.
Gate Operator Interface
For an automatic gate, the keypad relay can commonly be used as a dry-contact access command connected to the gate operator's designated access-control input. Verify whether the operator requires a momentary N.O. contact, N.C. contact, or another interface before wiring.
The SK-1323-BPQ is not a replacement for the gate operator control board and should not be used to bypass monitored safety or entrapment-protection inputs.
Two Egress Inputs
Two normally-open egress inputs allow compatible request-to-exit devices to trigger Output 1 or Output 2 without entering a code or presenting a proximity credential.
Examples may include compatible exit buttons or other dry-contact request-to-exit devices. Confirm the required contact type before connection.
Door Sensor Input and Anti-Tailgating
The keypad includes a normally-closed door sensor input for door-status and anti-tailgating functions. When configured with an appropriate door contact, the keypad can use door status as part of its relay-control operation.
This input is an access-control function and is not a substitute for monitored gate entrapment protection.
Optical Tamper Sensor
An optical tamper sensor is located on the rear of the keypad. When the tamper feature is enabled, exposure of the sensor can activate the keypad's tamper alarm if the unit is removed from its mounting surface.
Wrong Code and Invalid Card Lockout
If an incorrect user code is entered or an invalid proximity card is presented five consecutive times, the keypad enters a one-minute lockout. Additional keypad activity or card presentations during the lockout can extend the lockout period.
SK-1323-BPQ vs. SK-1323-BDQ
| Model | Credential Capability |
| SK-1323-BPQ | Black keypad with built-in 125kHz proximity reader |
| SK-1323-BDQ | Black digital keypad without proximity reader |
The housings and many access-control specifications are similar, but the models are not functionally identical. Order the BPQ version when proximity card or key-fob access is required.
SK-1323-BPQ vs. SK-1323-SPQ
- SK-1323-BPQ: Black housing with 125kHz proximity reader.
- SK-1323-SPQ: Brushed-aluminum housing with 125kHz proximity reader.
Verify the exact suffix and housing finish when replacing an existing keypad.

Technician Note
For gate operator installations, use the keypad relay as the proper access-control command whenever the operator provides a designated dry-contact input. Do not attempt to power a gate operator or high-current accessory directly from the keypad relay.
For electric locking hardware, verify the lock voltage, current, fail-safe or fail-secure configuration, and required transient suppression. SECO-LARM supplies diodes and MOVs for applicable lock installations; follow the current wiring instructions for the specific load.
Installation and Safety Notes
SECO-LARM instructs installers using the keypad with a mechanically operated door or gate to mount the keypad at least 5 ft away from the moving door or gate so a user operating the keypad is not positioned in the moving system's path.
The SK-1323-BPQ is an access-control device. It does not replace required monitored photo eyes, safety edges, emergency access equipment, fire-access provisions, door reversal systems, or gate operator entrapment-protection circuits. Never bypass required safety devices to make a keypad installation operate.
