Optical Thermal Multi Sensor with isolator, Morley-IAS

The multi-criteria multi-sensor MI-PTSE Photo Thermal detector uses thermal assistance to the core photoelectric smoke detector to give enhanced false alarm immunity and faster response to a wide range of incipient fires. The plug-in unit combines two separate sensing elements that are managed by embedded software to act as a single unit.

For smoke detection the MI-PTSE incorporates an improved sensing chamber design, linked to sophisticated processing circuitry with smoothing filters. This helps to eliminate the transient environmental noise conditions which can be the cause of false alarms. The sensor's performance is further enhanced by the integration of special algorithms which automatically compensate for contamination of the sensing chamber. This enables the sensor to provide a consistent level of sensitivity and increased immunity to unwanted alarms.

The thermal detection function combines thermistor technology with a software corrected linear temperature response.
