Quadnet Control Panel Engineering and Commissioning Manual
Field cable screen connection
Outputs 5 and 6: MO+, MO-, SCRN
Outputs 5 and 6 are monitored circuits which may be configured to monitor for open and short circuit faults
with a 10K EOL resistor, and to be activated with a stage 3 alarm.
The default setting for outputs 5 and 6 causes the circuits to operate as Common Fire Sounder Circuits,
where the outputs turn on in the alarm condition. Various other states may also be set using the Quadnet
OSP programming software.
The maximum output current for each output is 200mA. These outputs are protected by the 315mA T
fuses labelled FUSE 1 and FUSE 2.
Monitored Output positive connection
Monitored Output 0V connection

Auxiliary Power: +24V, 0V, SCRN
An auxiliary nominal 24V DC power supply is available to power ancillary devices requiring up to 30V DC.
The maximum output current is 200mA. The Auxiliary Power is protected by a F315mA fuse labelled FUSE
3. It is suggested that additional Power Supply Units be installed to provide power for additional loads.
Note: The auxiliary nominal 24V power supply output will be approximately 30 – 31V DC when the
panel is running from a mains supply and between 20 and 27V DC when running from the batteries
in a mains failure condition. Please ensure that the equipment to be powered from this output is
capable of operating from between 19V and 32V DC.
