5.2 Auxiliary Power Supply Output (24 V DC)
The panel is equipped with an auxiliary 0.5
А 24 V DC power supply output. Exceeding this
level causes fault condition. It can be used for supplying power to peripheral devices.
2x1,5 N2XH or 2x1,5 NYY cables should be used for external power supply line. In case of
mains power supply failure, the batteries provide power supply to the output (24 V DC).
(Annex-B, Figure-3).
5.3 Relay Outputs (3 Units)
The panel has 3 units of relay outputs with volt free changeover contacts rated 1A 30 V DC.
These volt-free outputs; fire relay (normally non-energized), alarm relay (normally non-
energized) and fault (normally energized). (Annex-B, Figure-5). 2x1,5 N2XH or 2x1,5 NYY
cable should be used for relay output line.
5.3.1 Fire Relay : The output is activated on any fire event and it can be used to trigger
any other system. The output is returned to its initial position only by pressing
‘Reset’ button
on panel.
5.3.2 Alarm Relay : The output is activated on any fire event and it can be used to activate
any other system. The output is returned to its initial position only by pressing
‘Alarm Silence’
button on panel. If a new alarm occurs, Alarm relay reactivates.
5.3.3 Fault Relay : The output is activated on any fault event, changes its contact in case
of mains failure. The output returns to its initial position, if fault condition is removed and the
‘Reset’ button on the panel is pressed.
Important notice : Fire alarm panel relays operate as signal-based relays. If these relays
will activate any other devices as like control relays, then a contactor should be used between
the relay and device. In case of high current driven applications, the relay outputs can get
damage if there is no contactor. This situation is not subjected to the warranty condition.
