Anti-condensation heaters
To combat the issue of lower temperatures causing condensation to form on detector lenses and reflective prisms, Fire Fighting Enterprises (FFE) has developed a new range of anti-condensation heaters for its Fireray range of optical beam smoke detectors.
The detector heater circulates a current of warm air over the lens, raising its ambient temperature by up to 10°C and maintaining the lens at an incrementally higher temperature than the surrounding air. This dramatically reduces the likelihood of condensation forming on the lens which, in turn, reduces the potential for false alarms.
The prism heater is an ultra-slim heating pad which is fixed behind the mounting plate. As with the detector heater, it maintains the temperature of the prism above that of the surrounding air, preventing condensation from occurring and reducing false alarms.
