Sounder circuits
The four sounder circuits are connected as follows:
Remove the 4K7 resistor from the sounder circuit terminals on the main PCB and fit to the last
device on each circuit
Circuits are fused at 500mA each.
Sounder circuit No 4 can be altered in the programming to be a remote signal output:
Output to Fire Alarm Routing Equipment
, monitored signal for use with remote, manned sta-
tions etc. EN54-2, section 7.9.1, option with requirements. When this is set in the parameters an
indication is given when this output is active (remote active). Also the output can be separately
disabled from other outputs and has its own unique indication (remote disabled / fault).
NOTE :
To comply with BS 5839 Part 1, at least 2 circuits should be utilised.
Remote relay contacts
Three sets of volt free changeover relay contacts are available for control functions. By default the
relays activate on a common fire basis.
NOTE
:
Fault relay is normally energised when the system is healthy.
Sounder circuit connection detail
Relay One
Programmable relay, energises on a Fire Alarm and de-energises on Reset
Relay Two
Programmable relay, energises on a Fire Alarm and de-energises on Reset
Common Fault
De-energises on any fault condition and stays de-energised until the fault is
cleared. ie: failsafe.
