There are two heat detectors in the AlarmSense range designed to suit a wide variety of operating conditions. A static heat detector (CS) which responds only when a fixed temperature has been reached and a rate-of-rise detector (A1R) which has a fixed upper limit, but in addition, measures the rate of increase in temperature.
As you would expect from Apollo, AlarmSense incorporates features that help reduce false alarms and patented technology to ensure the integrity of a system. The range also includes products, such as beacons, to help meet the requirements of the Disability Discrimination Act (DDA).
- Can be used for applications where smoke detectors are unsuitable
- Ideal environments that are dirty or smoky under normal conditions
- CS detectors are ideal for use in environments with rapid temperature fluctuations such as boiler rooms
- 360°C visibility of LEDs
- Reduction of false alarms
- Quick and simple installation
