Installation Manual
Connections 37
During STANDBY a low supervisory current with reverse polarity (with respect to the silk-screened
indications on the motherboard) circulates on the line. The diodes (connected in series to the loads)
will direct the current to the EOL resistor which must be connected in parallel to the last device (see
Figure 31).

7.8 PL terminal (for Shutdown signaling)
The Normally Open PL [22] terminal closes to GND (ground) in the event of control panel shutdown
(mains and battery power failure).
These terminals can be used to provide “Shutdown” signaling.
7.9 AUX output
The AUX output [23] provides a 24 V (27.6 - 1.8 A) power supply to external loads (ancillary
devices). This output is short-circuit protected by a resettable fuse.
In the event of short-circuit, the panel will signal an AUX output fault.
7.10 AUX R output
The AUX R output [24] provides a 24 V (27.6 - 1.8 A) power supply (which is removed temporarily
during control panel reset) to external loads (ancillary devices) that must switch off in order to reset
(e.g. beam detectors).
This output is short-circuit protected by a resettable fuse.
In the event of short-circuit, the panel will signal an AUX R output fault.
7.11 Alarm relay
The alarm relay provides a dry contact [26] which can switch loads of up to 5A (30 V max.). This
relay toggles its status in the event of panel alarm.
Attention: In order to validate the IMQ-SISTEMI DI SICUREZZA certification, this output should
not be used as a type C and/or E and/or J and/or G output (EN 54-1), therefore, it must
not be used to command fire alarm devices and/or fire alarm transmission devices.
7.12 Fault relay
The Fault relay provides a dry contact [27] which can switch loads of up to 5A (30 V max.). This relay
toggles its status in the event of panel fault.
Attention: In order to validate the IMQ-SISTEMI DI SICUREZZA certification, this output should
not be used as a type J output (EN 54-1), therefore, it must not be used to command
Fault transmission devices.
