HARD AND SOFT RESET FUNCTION

HARD AND SOFT RESET FUNCTION
▪
Hard Reset
When a hardware reset power cycle is performed, the CPU as well as the 27.5 V DC output is shut down and
restarted. Press and release button to perform this function.
▪
Soft Reset
When a soft reset power cycle is performed, only the CPU is shut down and restarted. The 27.5 V DC will remain
present. Perform this function by inserting the shunt jumper across the RST and GND pins for
3 seconds
, and then
remove it.
NB:
All LEDs on the PSU will switch on for +/- 1 second then off, showing the action has successfully been
completed.
5.2
FIRE ZONE CIRCUITS
Each detection zone circuit has an End-of-Line resistor (3k3) connected across the Zone + and Zone - terminal.
With each zone that is used, this resistor should be removed (factory connected to zone output) and reconnected
across the -ve and +ve (output) terminal of the last device installed on that zone (See drawing below). The panel
monitors this resistance and will react with a Fault condition if an open or short circuit is detected. A resistance of
680 Ohms across the circuit will produce a fire alarm (for Manual Call Points). Up to 20 detectors may be wired per
zone. For specific applications, please consult Technoswitch
NB:
A new feature has been added to identify if more than one EOL resistor has been mistakenly used on a
fire zone. The zone will go into Fault condition but the indicating LED will not flash but will remain
steady. Any other Fault condition (open or short circuit fault) will cause the indicating LED to flash until
the panel has been “silenced”.

DETECTOR BASE WIRING DIAGRAM
NB:
The earth of these devices must be terminated at the fire control panel only.
Detector base wiring may differ from those of Apollo S65 shown above. Please consult your detector wiring diagram for
the correct connections.
