SECO-LARM SK-1123-SDQ Vandal Resistant Outdoor Access Control Keypad
The SK-1123-SDQ is a rugged outdoor keypad built for access points where a light-duty indoor keypad will not hold up. It is commonly used on commercial pedestrian gates, warehouse doors, controlled equipment rooms, gated properties, and service entrances that need code-based access. The keypad is surface mounted, weather-resistant, and designed with vandal-resistant construction, making it a practical choice for exposed or semi-exposed locations. It provides two programmable outputs, visitor-code options, duress-code capability, and keypad programming without an external programmer. The SDQ version is for PIN-code operation only; it does not include the built-in proximity reader found on the SK-1123-SPQ version.
Compatible With
- Outdoor pedestrian gate and door access applications requiring a surface-mount keypad
- Gate operators with a low-voltage open, free-exit, or access-command input
- Electric strikes, magnetic locks, request-to-exit buttons, and door-position systems within relay ratings
- Sites replacing similar SECO-LARM SK-1123 series surface-mount keypads where wiring and programming match
- Applications requiring keypad codes, visitor codes, and two relay outputs without card access

Technician Note
The SK-1123-SDQ is a keypad-only unit. If the customer needs card or tag access, verify whether the SK-1123-SPQ or another proximity reader/keypad model is the correct item.
Before Ordering Checklist
- Confirm keypad-only operation is acceptable.
- Confirm surface-mount dimensions and mounting location.
- Match the relay output to the gate operator, lock, or access controller input.
- Confirm whether two outputs are needed for a second device, doorbell, alarm shunt, or auxiliary control.
- Document master code and user-code assignments after programming.
Professional Advisory
A qualified access-control or gate technician should handle wiring when the keypad controls an electric lock, gate operator, or any circuit tied to life-safety hardware.
Important Ordering Warnings
- Do not order SDQ if the installation needs built-in proximity card access.
- Do not exceed the relay output rating.
- Do not use keypad wiring to bypass monitored safety devices on a gate operator.
Product Questions and Answers
Does the SK-1123-SDQ include a proximity reader?
No. The SK-1123-SDQ is the digital keypad version. For a similar surface-mount keypad with built-in proximity reading, compare the SK-1123-SPQ or another compatible prox model.
Can this keypad be used outdoors?
Yes, it is made for outdoor access-control use, but it should still be mounted according to the manufacturer's instructions and protected from abuse when possible.
How many outputs does it have?
It has two programmable relay outputs, which can be used for access control and a secondary function when wired within rating.
Can it trigger a gate opener?
Yes, if the gate opener has a proper low-voltage access input. The keypad should not be wired to the motor power circuit.
What should be checked before replacing an old keypad?
Check the old model number, mounting style, power voltage, number of relay outputs, wire count, and whether the old unit used cards or codes only.
