Exitguard 12V Door Alarm for use with Intruder Panels
£95.60 (inc VAT: £114.72)
Summary
The Hoyles Exitguard EX125i is a self-contained, simple-to-operate solution designed specifically for the 24-hour protection of fire exit doors and other access points, with integration capabilities for Grade 2 EN50131 intruder alarm systems. This advanced door alarm unit combines local audible and visual alarm indication with comprehensive monitoring outputs that allow it to communicate with intruder alarm control panels from key manufacturers including Honeywell and Aritech.
The EX125i is specifically designed to monitor a door contact with end-of-line resistors and provide fully supervised loop outputs to allow the Exitguard to be monitored by a suitable intruder panel. Selectable resistor combinations (1k + 1k or 4k7/4k7) ensure compatibility with different intruder alarm panels, while the unit communicates alarms and faults to the main system via a supervised loop with separate alarm output. The system provides two supervised outputs: OP1 for door alarm monitoring and OP2 for keyswitch on/off status and box tamper indication.
Advanced features include auto sounder reduction to minimize noise nuisance after a preset period (with the sounder only restarting if the door is reopened), and the innovative Bleep In Off (BIO) function which provides an audible and visual alert when the unit is turned off, significantly reducing the chances of the alarm being forgotten in the disarmed state. The Safe Set feature prevents accidental alarm activations by providing a 15-second grace period to close the door after arming. With a high-power 108dB piezo sounder, selectable alarm tones, visual LED indication, keyswitch control with random key numbers, and comprehensive tamper protection, the EX125i provides a professional-grade security solution for protecting emergency exits while maintaining full integration with building intruder alarm systems.

FAQs
What is the Exitguard EX125i designed for?
The Exitguard EX125i is a self-contained door alarm specifically designed for integration with Grade 2 EN50131 intruder alarm systems. It provides 24-hour protection for fire exit doors and other access points while communicating alarm and fault conditions to the main intruder panel via supervised loop outputs.
How does the EX125i integrate with intruder alarm panels?
The EX125i provides two fully supervised loop outputs: OP1 for door alarm monitoring and OP2 for keyswitch on/off status and box tamper monitoring. Selectable resistor combinations (1k/1k or 4k7/4k7) ensure compatibility with different intruder alarm panels from manufacturers such as Honeywell and Aritech.
What is the Bleep In Off (BIO) function?
The Bleep In Off function provides an audible bleep and LED flash every 30 seconds when the keyswitch is in the off (0) position. Every 10 minutes, it also plays a louder tone. This reminds users that the Exitguard is disarmed, reducing the chances of it being forgotten in the off state. The BIO function can be enabled or disabled using a jumper on the PCB.
What is the Safe Set feature?
Safe Set prevents accidental alarm activations when arming the system. If the keyswitch is moved from off (0) to on (I) while the door is still open, a constant tone will sound but the alarm output OP1 will not change state. The door can then be closed within 15 seconds and the Exitguard will set normally. If the door remains open beyond 15 seconds, the unit will go into full alarm.
What is the alarm auto reduction feature?
Once an alarm is activated and the door has been closed for a minimum of 1 minute, the alarm sounder automatically reduces to a bleep every 30 seconds to minimize noise nuisance. The LED continues flashing and OP1 remains in alarm state. If the door is opened again, the full alarm sounder reactivates. Auto reduction only occurs when the door is closed.
How loud is the sounder?
The EX125i features a high-power piezo sounder producing 108dB at 1 metre, with selectable alarm tones for different applications. This ensures the alarm is clearly audible even in noisy environments.
What are the resistor configuration options?
The EX125i offers two selectable resistor combinations via jumpers: Position A provides 1k alarm resistor and 1k EoL resistor (Normal = 1k, Alarm = 2k), while Position B provides 4k7 alarm resistor and 4k7 EoL resistor (Normal = 4k7, Alarm = 9k4). Other resistor combinations are available on request to suit specific intruder panels.
How does the keyswitch monitoring work?
Output OP2 monitors the keyswitch position. When the keyswitch is in position I (on), OP2 indicates normal state. When the keyswitch is in position 0 (off), OP2 indicates alarm state, allowing the intruder panel to monitor whether the Exitguard is armed or disarmed.
What tamper protection is provided?
The EX125i provides two types of tamper protection: box tamper (if the lid is opened, OP2 goes open circuit) and door contact tamper (if the door contact is tampered, the unit plays a continuous tone when armed and OP1 provides a tamper condition to the intruder panel).
Can the EX125i be used for final exit doors?
Yes, with jumper J2 in the HI position, when the keyswitch is in the off position, opening the door will not generate a local alarm but OP1 will signal. This is useful when the monitored door is programmed as final exit, allowing OP1 to follow the door opening and closing to set the control panel.
What power supply is required?
A continuous supply of 12VDC is required, with 15mA maximum quiescent current draw and 150mA maximum during alarm conditions.
What is included with the EX125i?
All Exitguards are supplied with fixings, a door contact with 1 metre of cable, and a door warning sign. Replacement key barrels are available separately.
What are the dimensions of the unit?
The EX125i measures 175mm wide x 125mm high x 60mm deep (tapering to 50mm), with a compact ABS plastic enclosure suitable for wall mounting near protected doors.
