No	Explanation
1	Insert the tags into the holes first. Then fold the card down towards the stiffener.
2	Pin and pin strip for connection.

Relay card - description, connections and alarm outputs.

All fault arm relays must be in the drawn state. Check that there is a gap between CO and NC. Put the measuring instrument on continuity measurement and test closure. This should then indicate a short circuit.

All relay outputs are normally live and give an alarm in the event of no voltage.

There is normally a 10 second delay in alarm reset. The software on the main board must be configured for a different time period.
