Conventional Sounders is the term used to describe conventional
alarm sounders (or polarized bells) connected directly to a Panel.
Loop-powered Sounders are different and are connected to the
Analogue Loop.
Two Conventional Sounder circuits are provided on the Panel. More
than one Conventional Sounder may be connected to each circuit.
Max. current rating/Output is 500 mA @ 28.5V DC nominal.
All Conventional Sounder circuits are monitored for open and short
circuit faults. If a Conventional Sounder output is not used, then a
10K resistor must be connected across its output terminals.
WARNING:
The total current load of all detection loops, sounder circuits and auxiliary supply
outputs should not exceed the maximum power rating of the panel.
Please refer to the technical specification tables.
AUXILIARY FIRE RELAYS (2) AND FAULT RELAY (1)
Two auxiliary fire relay outputs are provided on the GEKKO Main
board. These outputs are activated when a fire is detected (unless
specifically inhibited). They are labeled AUX1 and AUX2. Under the
presence of any Fire Alarm condition, these 2 relays will be
energized. Both sets of contacts are of the change-over type.
Max. contact current rating for each set of relay contacts is
2 Amp @ 30V DC resistive / 0.5 Amp @ 125V AC resistive.
One auxiliary fault relay output is also provided. This relay output will
remain closed while there are no faults present in the system. Under
any fault condition present, the relay will be de-energized and the
relay contact will be open. The Fault relay is NC and it will open on
any fault on the system.
The contact ratings are:
2 Amp @ 30 V DC resistive / 0.5 Amp @ 125 V AC resistive.
WARNING:
Relay outputs are not supervised.
Please ensure that any wiring connected to these outputs is power limited.
