Numens - Model SNA-360-C2 -UL and EN approved smart smoke and heat detector
SNA-360-C2 analogue addressable photoelectric smoke/heat detectors are microprocessor controlled state-of-the-art detectors compatible with popular control and indicating equipment loop protocols. Up to 125 detectors can be connected to each alarm zone loop. 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. The SNA-360-C2 analogue addressable detector range provides fire detection and alarm system designers with a premium smoke/heat detector for life safety and property protection applications.· Dual photoelectric smoke and heat sensors to detect either smoke, heat or a combination of the phenomena
