The device is provided with an input for a Fireman's override switch and an input for any normally closed auxiliary devices or systems.
If these are not being used, then the connections must be linked out.
Two auxiliary outputs are provided.
They both signal the operation of the 'Emergency only' button and are momentary.
These outputs can be used for example to provide an input to an access control system for event monitoring, or could be used to trigger a sounder.
The outputs can be normally open or normally closed depending on the position of the associated jumper –
The default setting is for the jumper to be in the normally open position.
