Hoyles EXITGUARD EX125i Quick Start Manual

EXITGUARD EX125i
24 hour Door Alarm
The EX125i 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 (1k/1k) and provide Fully
Supervised Loop 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 EX125i is controlled using the built in key switch. With the jumper J2 in the LO position, when the
keyswitch is in the 0 (off) position, the protected door maybe opened without generating any form of alarm.
With the jumper J2 in the HI position, when the keyswitch is in the 0 (off) position, the protected door maybe
opened without generating a local alarm, but OP1 will signal as alarm if the monitored door contact is
opened. (This is useful if the monitored door is programmed as final exit, then the OP1 follows the door
opening and closing to set the control panel).
If the key switch is in the I (on) position, opening the door will result in a high powered audible alarm from
the EXITGUARD, the units LED 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 0 position.
Bleep In Off function
The EX125i includes the Bleep In Off function which while the keyswitch is in the 0 position, causes the
EXITGUARD to bleep and flash its LED every 30 seconds. Every ten minutes that the EXITGUARD is left in
the 0 position it will also briefly play a louder tone.
The Bleep In Off function can be turned on or off using the associated jumper on the PCB.
Alarm Auto Reduction
If the alarm is activated by opening the door when the keyswitch is in the I position, once the door is closed
for a minimum of 1 minute, the alarm sounder will reduce to a bleep every 30 seconds. During the reduced
alarm the LED will continue to flash and OP1 will remain in alarm. Should the door be opened again, the full
alarm sounder will activate again. If the door remains open, the Auto Reduction feature will not take effect.
Safe Set
To prevent accidental alarm activations, the EX125i incorporates a safe set feature. If the keyswitch is
moved from the 0 to the I position while the door is still open, a constant tone will be heard and the alarm
output OP1 will not change state. The door can then be closed within the next 15 seconds and the
EXITGUARD will set without having to move the keyswitch back to the 0 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 EX125i 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 position I, the normal state is indicated. If the
keyswitch is in position 0, 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 I position, the EXITGUARD will play a
continuous tone and OP1 will provide a tamper condition. If the keyswitch is in the 0 position, a door contact
tamper will just change OP1 to the tamper condition and the tone will not be heard.
Output resistors
The two outputs OP1 and OP2 both have two sets of resistor combinations selectable by four different
jumpers on the PCB. With all four jumpers in position A, the alarm resistor is 1K and the EoL resistor is also
1k for OP1 and OP2. With all four jumpers in position B, the alarm resistor is 4K7 and the EoL resistor is 4k7
for OP1 and OP2.
Other resistor combinations to suit other intruder panels are available on request.
Power requirements
A continuous supply of 12vdc is required, 15mA max quiescent and 150mA max in alarm.
