DIAMETER OF BASE IS 114MM, OVERALL HEIGHT INCLUDES THE TERMINAL IS 29MM.
THE PRODUCT IS AN INDOOR MOUNTING DEEP PLASTIC BASE CONFIGURED FOR OPERATION AS A RELAY BASE. WITH FITTED METAL TERMINALS & PRINTED CIRCUIT BOARD FOR CONNECTION OF CONVENTIONAL SMOKE OR HEAT DETECTORS TO EXTERNAL POWER SOURCES & TO COMPATIBLE FIRE ALARM CONTROL SYSTEMS. THE RELAY CAPABILITY ALLOWS FOR REMOTE DEVICES SUCH AS DOOR HOLDERS OR OTHER SAFETY EQUIPMENT TO BE TRIGGERED BY THE MOUNTED DETECTOR GOING INTO ALARM CONDITION. ONCE TRIGGERED, THE RELAY CIRCUIT WILL RETURN BY ITSELF TO NORMAL OPERATION WHEN THE BASE AND MOUNTED DETECTOR ARE BOTH RESET BY MEANS OF INTERRUPTION TO THEIR POWER SUPPLY.
A MOUNTING PLASTIC BASE WITH FITTED METAL TERMINALS AND PRINTED CIRCUIT BOARD FOR CONNECTION OF CONVENTIONAL SMOKE OR HEAT DETECTORS TO EXTERNAL POWER SOURCES & TO COMPATIBLE FIRE ALARM CONTROL SYSTEMS. ITS NORMAL OPERATING VOLTAGE IS 12V DC (DIRECT CURRENT). THE MOUNTING BASE IS CONFIGURED FOR OPERATION AS A LATCHING RELAY BASE. ITS LATCHING RELAY CAPABILITY ALLOWS FOR REMOTE DEVICES SUCH AS DOOR HOLDERS OR OTHER SAFETY EQUIPMENT TO BE TRIGGERED BY THE MOUNTED DETECTOR GOING INTO ALARM CONDITION. ONCE TRIGGERED, THE RELAY CIRCUIT REMAINS LATCHED IN ITS OPERATIONAL STATE & THE BASE DOES NOT RESET THE MOUNTED DETECTOR, ALLOWING FOR EASY IDENTIFICATION OF WHICH DETECTOR HAS CAUSED AN ALARM.
