The Transformer Rectifier is a dual purpose,
smoothed power supply providing either an
energised or de-energised output upon activation.
The output may be activated by utilising a set of
volt free contacts from a fire or security panel, or
by providing a 12/24Vd.c. trigger voltage from
other apparatus. The transformer rectifier units
are normally used to control the operation of
other 24Vd.c. equipment such as the magnetic
door retainers. The units are ideal for applications
where the supply is to be energised from a
remote source.

Door Release Power Supply
The C2400 series power supply equipment
provides primary and secondary power for fire
alarm systems. The power supply consists of an
AC supply operated charger, a stand-by sealed
lead-acid battery and an attractive housing. Under
normal conditions, the charger provides all the
system power and maintains the battery in the
charged condition. When the AC supply fails, the
stand-by battery takes over.
Features
• A range of chargers and housings to suit
different system configurations
• May be used with both conventional and
analogue addressable fire systems
• Large aluminium heatsink eliminates need for
unsightly ventilation grills
• Temperature compensated output ensures
correct charging voltage at all times
• Automatic protection for short-circuit
conditions is designed to prevent damage
• Optional voltmeter and ammeter
