SECO-LARM SK-2323-SDQ Mullion-Style Weatherproof Digital Access Keypad
The SK-2323-SDQ is the mullion-style version of SECO-LARM's weatherproof stand-alone keypad family. Its narrow face makes it useful on storefront mullions, gate posts, narrow door frames, pedestrian-gate columns, and other locations where a wider keypad housing will not fit cleanly. It provides code-based access with two relay outputs, egress inputs, door sensor input, tamper sensing, and backlit keys. The SDQ model is for keypad-code entry only. If the job requires card or tag access, the related SK-2323-SPQ proximity version should be checked instead. Correct selection depends heavily on mounting width, wire clearance, relay use, and whether the keypad is replacing an older mullion unit.
Compatible With
- Narrow mullion, frame, post, and column installations where a compact keypad is required
- Outdoor pedestrian gates and controlled doors requiring code-only access
- Gate operator low-voltage access inputs that accept dry-contact relay control
- Electric strikes, magnetic locks, egress buttons, and door sensors within published ratings
- Replacement for compatible SK-2323-SDQ installations where width, wiring, and programming match

Technician Note
Mullion keypads are often chosen because of mounting space, but wiring clearance behind the frame or post can be just as important as the face width.
Before Ordering Checklist
- Measure the available mullion or post width.
- Confirm code-only operation is acceptable.
- Verify the output wiring and relay rating.
- Check whether the old keypad used a separate reader or built-in card reader.
- Plan cable routing so the housing seals correctly after installation.
Professional Advisory
Use a qualified installer for metal-frame, gate-post, or electric-lock work where drilling, conduit, or access-control wiring can affect door or gate operation.
Important Ordering Warnings
- Do not confuse SDQ with SPQ; the SDQ model does not include proximity reading.
- Mullion fit depends on both face width and rear wiring space.
- Do not wire this keypad to high-voltage gate operator circuits.
Product Questions and Answers
Why choose the SK-2323-SDQ instead of SK-1323-SDQ?
The SK-2323-SDQ is narrower and better suited for mullions, posts, and tight mounting areas. The SK-1323-SDQ uses a wider sealed housing.
Does it include a proximity reader?
No. The SK-2323-SDQ is the code-only digital keypad. Check the SK-2323-SPQ if a built-in proximity reader is required.
Can it be used outdoors?
Yes, it is a weatherproof keypad family, but correct sealing, mounting, and conduit work are still important.
Can it trigger a gate?
Yes, if the gate operator has a compatible low-voltage access input. It should not be connected to motor power or safety-device circuits.
What should I check before ordering?
Measure the mounting width, confirm SDQ versus SPQ, check power voltage, count the required relay outputs, and compare the old wire connections.
