Q: Which fireproof connector should be selected for fire alarm detectors in building security systems?

A: Choose the flame-retardant LD series connector (IP65). Its shell is made of UL94 V-0 grade flame-retardant plastic that self-extinguishes when exposed to fire and produces no toxic gases, complying with the GB 5135.1 fire protection standard. 4 pins are used for alarm signal and power supply transmission, with a plugging life of ≥1000 cycles for convenient regular detection and replacement of detectors. It also has 5g vibration resistance (adapting to slight building shaking) and a temperature resistance range of -20~80℃, covering the environments of different building floors.
