The MI100 input module is a battery-operated device that transmits the status of an equipment to the fire detection central station through MC100 control unit module. The module has a monitored input of the ON/OFF type that must be connected to a normally-open contact and controlled by the equipment to be controlled. If the contact is closed, the wireless input module sends an alarm message to the MC100 module that reports it to the fire detection control unit connected to it. The module input is of the supervised type and uses a line end resistor that must be placed close and in parallel to the alarm contact on the device to check; an opening or a short-circuit of the connection line between the module input and the device contact generates a fault message from the input module towards the MC100 module and the subsequent report to the fire detection control unit.
Alarm and fault signals can reach the MC100 module directly or through one or more ESPMC100 radio add-on modules.
Communication between the input module and MC100 and ESPMC100 modules takes place in radio mode through a bidirectional protocol.
