1. Signal line: generally flame-retardant/fire-resistant red and blue twisted-pair cord (red positive and blue negative), smoke detectors, temperature detectors, manual alarm button signal modules, etc. are connected to the signal lines. Such as water flow indicator, alarm valve, fire damper, quick release valve, etc. are connected to the signal line and the alarm host through the signal module.
2. Power cord: generally flame-retardant/fire-resistant red and black twisted-pair soft wire or flame-retardant BV hard wire (red positive and black negative), the control module needs to be connected to the signal line and the power line. If the alarm bell has an address, it is directly connected to the signal line and power line. If there is no address, connect the signal line to the power line through the control output module. Such as air supply valve, smoke exhaust valve, electric valve, electric smoke outlet, blower, make up fan, smoke exhaust fan, air compressor control and forced cut non-fire power supply, elevator, etc., connect the signal line and power line through the control module and finally Connect to the alarm master.
3. Hard pull cable: some equipment needs to be directly controlled by the fire control room through a multi-line manual control panel, such as fire pumps, sprinkler pumps, fans, exhaust fans, etc. Generally, 6/4 core sheathed cables are generally used according to the equipment manufacturers Or 6/4 flame-retardant BV hard wires.
4. Broadcasting cable: generally flame-retardant/fire-resistant twisted-pair cord, used for the connection of the fire control broadcast host and the broadcast speaker in the fire control room.
5. Telephone line: generally a flame-retardant parallel flexible cord, used for the connection of the telephone host in the fire control room and the fire telephone and telephone jack.
The last thing to explain is that the more special fire hydrant alarm button line, generally 6 lines, of which 2 signal lines are connected to the alarm host, 2 direct pump lines are connected to the pump room water pump controller, and 2 return light signal lines Also taken from the pump controller in the pump room.
