SNA***0 analogue addressable photoelectric smoke/heat detectors are microprocessor controlled state-of-the-art detectors compatible with popular control and indicating equipment loop protocols.
Advanced electronics in conjunction with a photoelectric smoke sensing chamber and an electronic thermistor provide early detection of fire and high immunity against unwanted alarms. The heat sensor provides sensitive rate-of-rise operation or fixed-temperature operation when the response threshold value is exceeded.

Features:

·    Photoelectric smoke and heat sensors
·    Analogue detection discrimination
·    Dual LEDs for **0° visibility
·    DC *4 V operation
·    *-wire connection to many popular loop protocols
·    DIP switch address setting
·    **5 usable detector address settings per loop
·    Optional remote LED output
