9. AOV distribution PCB connections
SRL1 – 24 v dc out only on closing 0 volts at all other times
24V DCINPUT – Input from Power Supply unit – observe polarity
SRL2 – 24vdc out continuously in quiescent 0 volts out on opening
LINK2 – Break closed link to get output volts from ACT 1 & ACT 2
Remake reverses.
LINK1 – Break closed link to get output volts from ACT 1 & ACT 2
Remake reverses.
EXT FIRE OVERRIDE – Connection for “Fireman’s” control if required
ACT1 +/- 24vdc output to actuator on system activation reverse voltage on
reset
ACT2 +/- 24vdc output to actuator on system activation reverse voltage on
reset
10. Power Supply – PSF-243 (3Amp) & PSF-245 (5 Amp)
Lid Indicators Green Green = Supply Healthy Amber = Fault
When the Green light only is illuminated, the unit is operating normally with supply to
the load and the batteries (when fitted) are receiving charge current. When the Amber
light is illuminated at the same time as the Green light there is a fault on either or both of
the output supply and the charge supply. If the Green light is NOT illuminated, the mains
supply is not present or the main “overload” fuse has blown.

PCB Indicators
Amber (LP5) = Short circuit fault/supply fault.
Amber (LP6) = Charge output fault.
LP5 illuminated is either a short circuit in the wiring, or an excessive load.
LP6 illuminated is blown fuse (adj relay) in the battery charge output (i.e. Short circuit of
the battery leads) or by output supply short circuit. It is essential the battery is not fitted
“REVERSE POLARITY” as this will cause damage to the charging circuit which may be
irreparable.
Battery Connections
Two batteries (typical types to be used are Yuasa NP12-7) in equal state of charge are
required to make up 24V. The supplied leads should be used.
.
Battery Cut-Out
During A.C. failure the system will switch to battery standby, the output voltage level
will follow that of the batteries down to approximately 19V. At this point the cut-out
circuit for battery protection will disconnect power altogether. Should A.C. not be
available when testing with healthy batteries, a quick short on J11 pins will activate the
battery cut-in to power the load. (if there is sufficient charge in the batteries)
Fault Relay
The fault relay output will go from normal to fault state when A.C. power is removed or
when there's a fault in the unit as indicated by LP5 or LP6..
