The fire engine always fails to report: does the fire hydrant button report model not conform to the problem?
For the bus system, the fire hydrant button is monitored by the module, belonging to the alarm point of the fire alarm host, and the hand newspaper is also monitored by the module, all of which belong to the module signal circuit. The addressable detector can be used separately by a different type of host, and the no address detector is monitored by a module, so it belongs to the module signal circuit.
Very simple, the equipment alone in the host (loop, called the fault should be removed) if it continues to change, it is basically normal weight code because a check it slowly.Another reason is that because the host doesn't match the device, it's basically impossible. The old machine (dial code switch) can't afford new equipment (electronic coding)
Fire hydrant button general role is to start fire hydrant water pump, according to the design requirements, if you need fire alarm system monitoring, you can also start the fire pump through the alarm linkage, or you can pull the pump straight. However, general design requires surveillance.
There is a circuit board on the fire master, and a pair of 24V signal buses are drawn from the circuit board to the scene.The wrong reason for the fire hydrant button is incorrect (replacing the same model), and the address code is wrong (adjust address code). If the signal bus is broken or the resistance is low, you can directly connect the hydrant button to the circuit board to see if the fire hydrant button is normal,24+ connects S+ to S-
