SPECIFICATIONS Operating voltage 15 – 32 VDC (peak) Maximum current upon activation due to short circuit Refer to the manual for the main FACP Standby current 450 μA maximum; HM-DISO-UL is not isolated through a closed relay Temperature range 32°F to 120°F (0°C to 49°C) Relative humidity 10% to 93% Weight 5 oz. (150 grams) Dimensions 4.5”H x 4.5”W x 0.25” D (11.43 cm H x 11.43 cm W x 0.635 cm D) Construction The face plate is made of off-white plastic. Module includes yellow LED indicator that pulses to indicate normal conditions and illuminates steady when a short is detected. Operation The circuit is automatically opened when the voltage line drops below four volts. Fault Isolator Modules should be spaced between groups of addressable devices (maximum 25), in a loop that protects the rest of the loop. If a short occurs between any two isolators, then both isolators immediately switch to an open circuit state and isolate the groups of sensors between them. The remaining units on the loop continue to fully operate. The HM-DISO-UL Fault Isolator Module automatically restores the shorted portion of the communications loop to normal. Installation • Mount on a standard junction box (4.0”/10.16 cm square) which is at least 2.125”/5.398 cm deep • Terminal screws are provided for “in and out” wiring • Installation instructions are provided with each module • Surface mount box available Chia sẻ:
