Fire Alarm System Bus Loop Short Isolation Module

Linkage fire alarm system ring loop or tree loop isolation module for TC addressable fire alarm system. TCMK5210 Wiring type: Non-polar two bus Type: Isolator Action Current: 170mA/270mA Load Capcaity: Loop,24V,170mA/270mA (B, ZX2 short circuit) Mounting Hole Distance: 60mm Ingress Protection Rating: IP30 Specification: 86mm*86mm*40mm (with base) Approval: LPCB, CE, GOST how to wire loop isolator Bus short circuit isolator is simply called bus isolator. It is necessary to install bus short circuit isolator in bus automatic fire alarm system. When a bus fails, the bus isolator automatically separates the faulty bus part from the whole system to ensure the normal operation of the rest of the system. At the same time, the fire alarm controller indicates the part number of the isolated parts, which is convenient for maintenance. When the fault is rectified, the bus isolator automatically reintegrates the isolated part into the system. When a fault such as short circuit occurs at a certain position in the bus, the short circuit isolators on both sides of the bus will act to isolate this section of line without affecting the normal work of other bus devices in the circuit. When the fault is rectified, the isolator automatically reintegrates the isolated part into the fire alarm system.
