INSTALLATION NOTE
FAAST Power Supply AUX24V-1.3A
Pertronic Industries Ltd1 FAAST Power Supply Installation Note, Iss 1.1 201501
Overview
The
Pertronic FAAST Power Supply AUX24V-1.3A
is a 24 Volt DC self-monitoring power supply suitable
for powering ancillary fire alarm equipment including the FAAST range of aspirating smoke detectors. The
unit incorporates a switched-mode mains power supply and an automatic voltage monitoring and battery test
module.
The internal monitoring system continually checks the power supply’s output voltage and verifies that the
batteries are connected. At 24-hour intervals, the monitoring system automatically checks the battery
capacity.
A changeover relay indicates when the monitoring system has detected a fault. A front panel LED provides
local fault identification.
The cabinet will accommodate a pair of 12-Volt sealed lead-acid batteries with a capacity of up to 12 Amp-
hours. If larger batteries are needed, a Pertronic 4 Amp power supply (
Auxiliary 24V-4A PSU
) should be
used.
The power supply is supplied without batteries. The battery calculator on the Pertronic Industries web site
may be used to work out the size of battery needed for a particular application.
