provide contact outputs for use with 3
rd
Party devices.
The fields listed under the “CS Relays” tab allow the user to configure the
common system relays to follow groups as required.

The default setting for this relay is Horn A / HNA, the relay is normally de-
enegised and provides a N/O contact for use with external audibles / 3

Acknowledge have been pressed. The relay must be assigned to a group and
the group type needs to be set as “Audible” for the relay to operate correctly.
The coil state can be set to Normally Energised or Normally De-
Energised, by selecting the required feature using the Drop-down
menu shown next to the coil status field.
