The EM312SR module connects to the loop and has a supervised input (able to control the status of an external device), a supervised output (able to drive one or more acoustic or optical/acoustic signalling devices) and a free exchange output (able to drive any external device such as electromagnets etc.).

1 supervised input.

1 supervised output.

1 external voltage input (supervised) for activating devices connected to the output.
