INSTALLATION AND OPERATION MANUAL
25-16328-B November 2020 www.eaton.com
Section 1: System installation and design
Panel outputs
Panel Sounders: (OPTION 7 .8 EN54 PT 2)
Two pairs of outputs are provided . ONLY polarised equipment should be used .
Ensure the polarity of the connections are observed at all times and end of line
resistors & Diodes) are fitted for correct operation .
The total alarm load across all sounder outputs = 1 .5 Amp
All outputs are fused with 1 .6 Amp Glass fuse Alarm devices should be spread
equally across the 2 sounder circuits .
WARNING
Do not exceed the rated output current .
All sounders must be polarised
OUTPUT TO FAULT WARNING ROUTING
EQUIPMENT (OPTION 9 .4 .1C EN54 PT 2)
This output, which is fused and monitored
using 2k end of line resistor is used for the
transmission of fault signals to fault warning
routing equipment . This output is monitored
using 2k0 end of line resistor and it current
limited to 30 mA .
Under normal conditions it operates by providing 12vdc which can be connected
directly to a 24v auxiliary device
(relay) .It is current limited to 30 mA .
Under fault conditions or even if the Panel is switched off, this output will switch to 0
volts . Ensure the polarity of the connections is observed at all times and end of line
resistors (2k0 5%) are fitted for correct operation .
Auxiliary Relay (OPTION NOT REQUIRED BY EN54)
This output is a volt free contact, which is protected by a polyswitch . It is rated at
24 Volts 1Amp . If operated under a fire alarm condition , this output will remain
energised until the fire alarm is reset .
AUXILIARY DC OUTPUT (OPTION NOT DEFINED BY EN54)
A 24 Vdc output is provided . This output is protected by a polyswitch . This output can
be used to power fire or fault auxiliary equipment . Please ensure that all equipments
connected to this output will only draw current when a fire condition exists .
WARNING
Do not exceed the rated output current .
End of line device.
Both sounder circuits must
be terminated with an end
of line device.
