Overview The VF5603-0M Discovery Multisensor Detector contains a photo smoke sensor and a thermistor temperature sensor whose outputs are combined to give the final analog value. The way in which the signals from the two sensor are combined depends on the response mode selected. The five modes provide response behavior which incorporated pure heat detection, pure smoke detection, and a combination of both. The multisensor is therefore useful over the widest range of applications. The outer smoke chamber has inlet aperatures fitted with insect resistant mesh. Operation The signals from the optical smoke sensing element and the temperature sensor are independent, and represent the smoke level and the air temperature respectively in the vicinity of the detector. The detector's microcontroller processes the two signals according to the mode selected. When the detector is operating as a multisensor (i.e. Modes 1, 3, and 4) the temperature signal processing extracts only rate-of-rise information for combination with the optical signal. 20 Second Alarm Delay Yes Yes Yes Yes No In these modes the detectors will not respond to a slow temperature increase- even if the temperature reaches a high level. A large sudden change in temperature can, however, cause an alarm without the presence of smoke, if sustained for 20 seconds. The process algorithms in modes 1 to 4 incorporate drift compensation.

Modes The characteristics of the five response modes are summarized below. Mode 1 has a very high smoke sensitivity combined with high temperature sensitivity. This gives a high overall sensitivity to both smoldering and flaming fires. Mode 2 has smoke sensitivity similar to that of a normal photoelectric detector, but has no response to temperature. This mode is therefore equivalent to a standard photo detector. This mode is suitable for applications in which wide temperature changes occur under normal conditions. Mode 3 has moderate smoke sensitivity combined with moderate sensitivity to heat. This...
