Overview
What it is and how it fits the system.
The 800371 is an ES Detect non-addressable optical smoke detector designed for conventional fire systems, providing safe and early detection of fire. It operates from 8 to 42 V DC with a typical 9 mA alarm current at 9 V DC and roughly 30 uA quiescent draw. Rated for application temperatures up to 72 C and air speeds to 25.4 m/s, with IP43 ingress protection achievable using the base and option.
Technical overview
The 800371 is a Conventional ES Detect non-addressable optical smoke detector designed for operation on conventional fire systems, providing safe and early detection of fire. It operates from 8 to 42 V DC with a typical alarm current of 9 mA at 9 V DC and a quiescent draw of approximately 30 µA. Rated for application temperatures from -20°C to 72°C and air speeds up to 25.4 m/s, it achieves IP43 ingress protection when used with the appropriate base and option.
Constructed from ABS material in white (similar to RAL 9010), the detector weighs approximately 110 g and has dimensions of Ø 117 mm with a height of 49 mm (62 mm including base). It is compatible with the standard detector base 805590, the diode-equipped base 805590-D for removal monitoring, and remote LED 781814. The device is approved for use with Xenex control panels including models 13270-02LB, 13270-04LB, and 13270-08LB. For physical wiring details, refer to the installation manual.
