Gent Fire Alarm Frequently Asked Questions

  • What is a intruder alarm system?

    An intruder alarm system detects intrusions, attempted intrusions and unauthorised entry into a building, particular room, or construction site. By installing an intruder alarm system on your commercial building you or whoever is monitoring your system will be notified when unauthorized entry is attempted. The vast majority of intruder alarms will generate noise when altered to try and prevent intrusion whilst it's happening.

  • How does an intruder alarm work?

    The main mechanism in an intruder alarm is motion sensors, and shock sensors. These can be installed both internally and externally to detect movement and impact / vibrations. These sensors will relay information to the main system and initiate the alarm, and send notifications to you, or whoever monitors your system.
