Connection of the relay outputs
Selection of the three relay operating modes is done the jumpers X10 to X15 on the board of the third-
party detector connecting module. Furthermore the relay operating mode must also be edited in the
customer data of the ESSER fire alarm control system.
Different operating modes may be used for the two relay outputs. This allows for mixed operation of a
third-party detector connecting module.
The relay outputs are protected by an electronic protecting device (Multi-Fuse). To reset this protection,
supply power must be removed from the third-party detector connecting module for a duration of approx.
30 seconds.

Operating mode 1 - relay monitoring
When a relay is activated, the internal 12 V DC supply voltage (terminal X1) is switched through to the
connected external device, e.g. on optical and/or audible signalling device.
Arrange jumpers (X10 to X15) for mode selection in to accordance with Fig.
settings for relay output 1: jumpers X10, X11, X12
