Spectron-804-Exi-H-Modbus fire flame detector

4-IC fire flame detector. Category of immunity - 1 (Maximum) super interference immunity to heavy optical interference. Recognise manual arc and argon welding as false interference! They are used in open areas and in closed rooms with heavy optical interference. Temperature range from - 55 to + 75°C. Viewing angle 90°. Flame detection range - 25 m at TP5 and TP6. 4 operating modes with different sensitivity and detection range. There are functions of self-testing and transmission of a signal failure, tested with a test light, but only with a 4-wire connection. It is possible to link the detectors to a specific lantern by means of an identification code. The function of not transmitting the FIRE signal to the communication line during testing with a torch, the function of not transmitting the FIRE signal to the communication line during testing with a magnet.
