Introduction
Congratulations on your purchase of a Gate Alarm. The Gate Alarm can be summarised as a single zone
alarm that is always armed and only temporally bypassed for a programmable time when the Bypass
input is triggered. The output is a dry contact consisting of a common, normally open and normally
closed contact allowing for total flexibility in what you connect as your signaling device. (Siren,
Transmitter, GSM Modem, Strobe)
Connections:
The green plug can be quickly removed for easy replacing of the unit
Power supply:12 v to 24 v Positive (1) Negative (2)
Bypass: A pulse from com (4) to bypass (3) will cause the alarm to be inactive for the time programmed
on Dip Switch 3 and 4. Typically this would come from the trigger input on the gate motors main board.
If the receiver is built into the main PCB and the Trigger input does not work then you could alternatively
use the courtesy light output, if this is not available then a relay can be connected to the cable going to
the motor. (i.e. if the gate is moving from the power on the motor and not being forced) This makes the
Gate Alarm compatible with any motor.
Zone: The zone (5) is what will detect the illegal opening of the gate and can be as simple as an industrial
reed switch or active beams. DIP Switch 1 will select between a normally open or normally closed zone.
For extra security DIP Switch 2 can be turned off to include a 3k3 End Of Line Resistor. The zone
completes the circuit back to Common (4)
Output: The output is a 'Dry Contact' (Not connected to the rest of the circuit) Normally open (6)
Normally Closed (7) Common (8)
DIP Switches:
SW1. Off = Normally Open. On = Normally Closed
SW2. Off = 3k3 end of line resistor. On = Logic
SW3 and 4. Selects the time the system will be bypassed, this should be a little longer that the gate takes
to close on its own.
SW5 and 6. Selects how long the output relay activates for.
SW7 and 8. Selects the duration of the cycle. The system will cycle until the zone is restored, this is to
ensure the system is always working
SW9. When off, the output will reset when the zone restores, When on the output will stay active for
the time set on DIP SW 5 and 6 regardless of the zone.
SW10. When off, the bypass time will reset when the zone closes and the system will be armed. When
on the bypass time will be determined by DIP SW 3 and 4 and the zone will not reset this time. Useful
when active beams are used without a reed switch and more than one car drive in an open gate.
SW9 and SW10 Both off will force both times and also disable the feature that sets off the alarm if the
gate doesn’t open within 4 seconds of the bypass being pressed. This would be done if for example an
outdoor motion sensor is used, it may not have picked up motion within the 4 seconds.
LED Lights:
Power: Flashing- Power on and processor running
Status: On- Zone Violated
Off- Zone Ready
Flashing-Zone Bypassed
Alarm: On- Alarm relay activated
Off- Alarm relay Off
Flashing- Alarm still active, but in cycle time with relay off
