Intruder Alarms


An intruder alarm is an integral part of any complete security solution.
Intruder alarms provide a visual deterrent as well as an active warning, should someone gain unauthorised access to your site or property. There are many different alarm systems and not all will meet your business and insurance needs.
With a GBSG alarm our qualified and experienced surveyors will help you assess the alarm that you need and offer you the right grade of alarm and monitoring to meet the level of risk that your business faces.
Based on your premises we can incorporate the following types of detection
Passive Infrared
This type of motion sensor is triggered by the detection of body heat within set parameters.
Microwave
Using microwave pulses to measure the reflection off a moving object, this type of detection can cover a large area but is not suitable for those sites that are vulnerable to electrical interference.
Dual Technology
A combination of passive infrared and microwave detection, dual technology detectors help to reduce the risk of false alarms because for the alarm to be activated, both sensors have to be triggered.
Shock Sensors
Fitted to windows and doors, shock sensors work through detecting both single and heavy impacts, such as someone trying to smash through the glass, and continued applied force.
