Hoyles EXITGUARD Manual

EXITGUARD EX125iS-HX
The EX125iS-HX EXITGUARD is a self contained simple to operate solution for the 24 hour protection of fire exit and other doors.
It is specifically designed to monitor a door contact with end of line resistors (2k2/4k7) and provide resistor biased outputs to
allow the EXITGUARD to be monitored by a suitable intruder panel. Selectable resistors allow the outputs to be configured for
different intruder panels.

General Operation

The EX125iS-HX is controlled using the built in key switch. With the OP1 mode switch switched to LO, when the keyswitch is in
the OFF position, the protected door maybe opened without generating any form of alarm. With the OP1 mode switch, switched
to the HI position, when the keyswitch is in the OFF position, the protected door maybe opened without generating a local
alarm, but OP1 will signal as alarm. (This is useful if the monitored door is programmed as final exit on an intruder panel, then
the OP1 follows the door opening and closing to set the control panel). If the key switch is in the ON position, opening the door
will result in a high powered audible alarm from the EXITGUARD, the units two LEDs will also flash. Additionally the alarm output
(OP1) will also provide an alarm condition to an intruder panel. Once in alarm, the only way to reset the EXITGUARD is to turn
the keyswitch to the OFF position.

Bleep In Off function

The EX125iS-HX includes the Bleep In Off function which while the keyswitch is in the OFF position, causes the EXITGUARD to
bleep and flash its LED every 60 seconds. Every ten minutes that the EXITGUARD is left in the OFF position it will also briefly play
a louder tone.
The Bleep In Off function can be turned on or off using the BIO switch on the PCB.

Alarm Auto Reduction

Once the alarm is activated, it will sound continuously whilst the door is open, but after the alarm has been sounding for approx.
1 minute with the door closed, the alarm sounder will reduce to a tone every 30 seconds. During the reduced alarm the LEDs
will continue to flash. The OP1 will clear during reduced alarm. Should the door be re-opened during the reduced alarm, the OP1
will switch and the full alarm sounder will activate again.

Safe Set

To prevent accidental alarm activations, the EX125iS-HX incorporates a safe set feature. If the keyswitch is moved from the OFF
position to the ON position while the door is open, a constant tone will be heard and the alarm output OP1 will not change
state. If the door is closed within the next 15 seconds and the EXITGUARD will set without having to move the keyswitch back to
the OFF position. However if the door remains open beyond the 15 seconds, the EXITGUARD will go into full alarm and the alarm
output OP1 will change to the alarm state.

Keyswitch On / Off Monitoring

The EX125iS-HX provides a second output OP2 which can be monitored by an intruder panel. This output indicates the status of
the keyswitch. With the keyswitch in the ON position, the normal state is indicated. If the keyswitch is in the OFF position, the
alarm state is indicated.

Box Tamper

If the box lid is opened OP2 provides a tamper to the intruder panel by going open circuit.

Door Contact Tamper

If the door contact is tampered when the keyswitch is in the ON position, the EXITGUARD will play a continuous tone and OP1
will change to the alarm state. If the keyswitch is in the OFF position, a door contact tamper will just change OP1 to the alarm
state but no alarm tone will be heard.
