The mains module is used to connect additional parts like horns or flashing lights to the EH-Exit Controller. As soon as an additional part is connected, "Operation” lights up on the mains module. If an alarm is triggered by the connected EH-Exit Controller, the "Alarm” display also lights up.
To enable the EH-Exit Controller to be operated without a battery, it must be connected with the mains module. As soon as the EH-Exit Controller is connected to the power source (socket) via the mains module, the internal battery must be disconnected.
