The JS-951E input model (JS-951E module for short) is used with a fire alarm control system. It can be connected with various passive, normally open on-off pieces of equipment, such as water flow indicators, pressure switches and other firefighting equipment. After the said equipment starts to operate, the alarm signal output will be sent by the JS-951E module to the fire alarm control system through a signal bus to give a fire alarm.
