In this application, the SA-027WQ is used to open and close a gate based on a
weekly schedule. The gate is required to remain open from 7:00am to 7:00pm Monday through Friday.
If the gate is set to automatically close after opening:
The relay is set in Fixed mode to activate at 7:00am Monday through Friday
The relay is set in Fixed mode to deactivate at 7:00pm Monday through Friday
If the gate is set to open or close based on a dry contact closure:
The relay is set in Pulse mode to activate for :02 seconds at 7:00am Monday through Friday
The relay is set in Pulse mode to activate for :02 seconds at 7:00pm Monday through Friday
A wireless remote (such as the SK-919TD1S-UP) activates the wireless receiver (such as the
SK-910RBQ), which is connected to the egress input of the SA-027WQ. This will activate the gate when
the timer is not in use.
In this application, the SA-027WQ is used to keep an entry door unlocked during
normal business hours.
The relay is set in Fixed mode to activate at 8:00am Monday through Friday.
The relay is set in Fixed mode to deactivate at 5:00pm Monday through Friday.
A fail safe electric door strike (such as the SD-996C-NUQ) is connected between the N.C. and (–)
terminals. A 1N4004 diode (not included) must be connected as close as possible to, and in parallel
with, the lock.
A Normally Open (N.O.) spring-loaded switch connected to the egress input of the SA-027WQ allows
for egress while the door is locked.
