Specifications:
1. Find a location for the SA-027HQ where the LCD display is easily seen and the buttons can be
pressed. Mark that location.
2. Open the case and connect the wires.
3. Connect a 12/24 VDC/VAC power supply to the power input terminals marked (+) and (-).
4. Connect the battery backup to the backup battery input terminals marked (+) and (-).
NOTE: For the best backup battery charging results, the power input should not be lower than
17VDC or 12VAC.
5. Remove the paper battery protector from the onboard clock backup battery.
NOTE: The paper protector prevents the battery from being drained during product shipment. If
the protector is not removed, the onboard clock backup battery will fail to function.
6. Connect the devices that are being controlled to the outputs of one or two relays.
NOTE: If using a DC-powered electric/electromagnetic lock, connect a 1N4004 diode in parallel
with the power supply and as close to the lock as possible. This absorbs possible interference
and prevents operation of the lock from damaging the timer. Not required for AC-powered locks.
7. Close the case and mount the unit.
