Honeywell – TC840M1021 Multicriteria Fire Sensor

The multi-criteria fire sensors are plug in fire detectors combining optical smoke detection, heat detection and microprocessor control with analogue addressable communications. For smoke detection, the sensors incorporates an improved design of sensing chamber, linked to sophisticated processing circuitry incorporating smoothing filters to help eliminate transient environmental noise conditions, which can be the cause of unwanted alarms.

The detector’s performance further enhanced by the integration of special algorithms, which automatically compensate for contamination of the sensing chamber, hence providing consistent level of sensitivity and increased immunity to unwanted alarm conditions. The thermal detection function features single thermistor technology with a linear temperature response. Special algorithms are used to process the inputs from both optical and thermal functions, before an alarm decision is made. These sensors are designed for open area protection and must only be connected to control panels that use a compatible proprietary communication protocol for monitoring and control. Intelligent, drift compensation algorithms allow the sensors to constantly adjust to its surroundings, thereby reducing false alarms due to contamination.
