Besides the terminals that were described up to now the panel also has the following outputs :
24V_M:
A 24V
DC
output that is interrupted in the event of a panel reset. It is mainly used for powering gas
detectors or other devices that need an interrupted power supply when the panel is resetting. If this output
is short
circuited then the LED marked 'General fault' is lighted.
24V_P:
A 24V
DC
power output that is not interrupted in the event of a reset. It can be used to power
electromagnetic door latches.
Relay Alarm :
Voltage free relay contacts
are activated when there is an
alarm condition.
Relay Fault :
Voltage free relay contacts
are deactivated when there is an fault
condition.
Relay AUX :
Voltage free relay contacts that by default
when one zone is in alarm condition
.
ATTENTION:
The
relays are rated at 30VDC and 5A maximum. No 230VAC signals can be connected
to th
ese
relays.
Siren - Sounder Connections
Each panel offers 2 independent circuits for connecting sirens, bells or other devices that need 24V
DC
in order
to operate. Each circuit can supply a maximum of
300mA
. Each terminal block by default has a pre-installed
terminal resistor (
8
Κ
2
). This terminal resistor is either removed and installed on the last siren of the line or is
left on the terminal block if the circuit is not used.
The connections of both circuits are identical.
