1. Introduction
This control unit is for use with most Automatic Opening Vents and can
be used with other equipment that requires reverse voltage for closure. It
can be connected to most Fire Alarm systems operating on 24v dc. The
unit includes a 27.6V DC charger for use with Sealed Lead Acid Batteries
sized accordingly to up to 7Ah. The output load connected to the unit
should not exceed 1 Amp on AOV-001, 3 Amp on AOV-003, 5 Amp on
AOV-005 and 10A on AOV007 (excluding battery charging). .
2. Supply
Supply to the unit should be 240V ac 50Hz (+/-5%) and be fed via an
unswitched 5amp -fused spur outlet, fitted adjacent to the unit. The mains supply
in the enclosure should be wired into the fused terminal block provided. The unit
should be earthed.
3. General operation
With mains 240Vac connected the unit will charge batteries via the PSU
pcb (when fitted correctly) and will give an output of 24v DC +15%/-10%
when activated by Fire Alarm Control Panel or other control system.
When reset is effected at the Fire Panel the unit will reverse the polarity of
the output. Care must be taken that any equipment connected will not be
damaged by this operation.
Note: When reset is effected there will be timed reverse polarity output
irrespective of whether a trigger input from a Fire Panel or other device
is present or not.
SW1 provides a fire override feature to close the actuators, over riding any
trigger input.
This unit also has a fault-monitoring relay on the psu PCB. The relay is
energised when the unit is operating under normal (fault free) conditions
and gives a set of voltage free contacts at the ‘Fault Relay Output’. The
relay will operate in tandem with the main lid fault LED. These contacts
can be used to signal faults to a remote monitoring system or to control a
remote indicator or audible unit if required
