SECO-LARM Enforcer SA-027WQ 7 Day Timer
The SECO-LARM SA-027WQ is a weekly programmable timer designed to operate a Form C relay on a recurring 7-day schedule. In the field, this type of timer is often used where a customer wants a gate, door, light, lock, alarm, or auxiliary circuit to follow a daily or weekly time schedule without tying the function to a full access-control software system. It can handle multiple programmed events and is well suited for simple scheduled access windows, holiday-light control, automatic door unlock periods, and other low-voltage control jobs.
For gate and access-control use, the important detail is that the timer is only switching a relay output. The connected device, operator input, lock relay, maglock relay, or control panel must still be wired correctly and rated for the load. The timer can be used as a command device, but it should not override required safety, fire, or code-required release circuits. Correct power supply voltage, relay contact usage, schedule programming, and backup battery condition should be verified before replacing an older timer.
Compatible With
Compatible with many low-voltage access-control, gate, garage, lighting, security, and environmental-control systems that can be controlled by a dry Form C relay. Common applications include timed gate open commands, scheduled door unlock periods, access-control auxiliary relays, lighting control, alarm signaling, HVAC or fan control, and general automation where a weekly schedule is needed. Verify the connected load, input voltage, relay rating, and whether the circuit must be normally open or normally closed.

Technician Note
Use the SA-027WQ as a control timer only. Do not wire it in a way that defeats monitored safety devices, fire release, emergency egress, or the normal protection built into a gate or door system.
Before Ordering Checklist
- Confirm the site needs a 7-day weekly schedule rather than a 365-day annual schedule.
- Confirm 12-24 VAC/VDC power is available.
- Match the relay contact rating to the controlled circuit.
- Record the existing NO, NC, and common wiring before replacement.
- Check whether holiday schedules or annual events require the SA-027HQ instead.
Professional Advisory
Access-control and gate wiring should be performed with the power disconnected and with the system wired according to the operator, lock, or access-control manual. Do not bypass required safety devices. For high-voltage circuits, delayed egress code requirements, or unsafe gate movement, use a qualified gate or access-control technician.
Product Questions
What is the SA-027WQ used for?
It is used to switch a relay on a weekly schedule for access control, gate commands, lighting, security, or other timed control circuits.
Is the SA-027WQ the same as the SA-027HQ?
No. The SA-027WQ is a 7-day timer, while the SA-027HQ is an annual timer with two relay outputs and more calendar-based scheduling.
Can this timer hold a gate open during business hours?
It may be used for that type of command if the gate controller supports a maintained or scheduled input and all safety requirements remain active.
What power does the SA-027WQ need?
It is commonly listed for 12-24 VAC/VDC low-voltage operation.
Does this timer replace an access-control panel?
No. It is a scheduled relay device. It can support simple timed functions, but it does not manage users like an access-control controller.
