Which Alarm where?
When installing or specifying Alarms, it is crucial to make sure you choose the right sensor type for the right location.
Optical
(Single sensor)
• Optical sensors use an infra- red beam to detect smoke and react to slow, smouldering fires such as electrical fires.
• These use a thermistor (heat sensor) which detects changes in temperature, and triggers the alarm at 58°C.
