3.10. 24 V AUXILIARY OUTPUT
The MAIN BOARD has a 24 V AUXILIARY OUTPUT. This output can
supply, for example, current to an external relay:
1. Check that:
• the external line is not shorted or
• earthed or diverted to any low voltage line or
• no end-of-line elements or diodes have been connected.
2. On the main board, locate the 24 V AUXILIARY OUTPUT (see
section 3.4).
3. Connect the + and - terminals to the corresponding cables.
The maximum output current is 500 mA, see section 3.4 of this
manual.
3.11. CONNECTING TO THE FAULT RELAY
The MAIN BOARD has a FAULT RELAY OUTPUT. This relay changes
status when it detects a fault in the facility:
1. On the main board, locate the R.FAULT connector (see section
3.4).
2. Connect the main NO (Normally Open), NC (Normally Closed)
and C (Common) cables to the corresponding terminals on the
MAIN BOARD.
The fault relay is ENERGISED. This means that, although the control
panel may run out of power, both from the mains network and the
battery, the relay will continue to indicate the fault status.
3.12. CONNECTING TO THE ALARM RELAY
The MAIN BOARD has an ALARM RELAY output. This output activates
when an alarm or an event configured as such is detected:
1. On the main board, locate the R.ALARM connector (see section
3.4).
2. Connect the main NO (Normally Open), NC (Normally Closed)
and C (Common) cables to the corresponding terminals on the
MAIN BOARD.

If you are going to use alarm or
fault contacts to activate inductive
loads, take the precaution of using
