SECURITRON POWER SUPPLIES
MODELS: BPSM-12-6, 9 AND 15; BPSM-24-4, 6 AND 10
OPERATION AND INSTALLATION INSTRUCTIONS
1. DESCRIPTION
These instructions cover 6 different models as shown above. The part number expresses first
the output voltage (12 or 24V DC) and second the maximum output current capacity. For
example, a model BPSM-24-6 can supply up to 6 amps at 24 volts. Securitron large power
supplies consist of a power module and CCS8M control board to which all installer connections
are made. The board accomplishes several functions. It provides terminals for line voltage
input and eight separate DC output circuits, so that a number of devices can be powered. Each
control circuit has an individual slide switch to turn it on and off and an LED to annunciate its
status. The CCS8M control board also provides the following:
 AC input and DC output LED indicators
 Emergency release terminals (fire alarm disconnect)
 AC status (form “C” contact) and DC status (form “C” contact) terminals
 Line voltage and DC fuses
 Built-in charger for sealed lead acid or gel cell batteries
 Automatic switch over to stand-by battery when AC fails
All power supplies in the BPSM series are Class 2 rated when installed following these
instructions.
The models which incorporate the suffix “H” in the part number have not been evaluated by UL.
These power supplies have only been evaluated by UL for use in the EXD-1and EXD-1F FWAX
systems.
2. SAFETY
Two hazards are present in the supply. Line voltage input presents a high voltage shock hazard
and the DC/battery output, represent a high energy (current) hazard. A shorted battery can
swiftly supply levels of current sufficient to melt wiring insulation and cause a fire. To insure
safety, note first that the cover LED (red) is on at any time that the supply is dangerous, which
is either if it is receiving line voltage or if batteries are operating. The supply enclosure must
only be opened by trained service personnel when the red LED is on. The green LED on
the CCS8M control board is on when AC line voltage is present. Other safety features
include line voltage and DC fuses and the fact that the line voltage input terminals are under a
warning guard plate.
3. OPERATING CHARACTERISTICS
3.1 LINE VOLTAGE INPUT
110-120 VAC should be input to terminals "H", "N", "G", as shown in the drawing. This is fed to
the input of the power module through factory made connections. The green LED will illuminate
when AC line voltage is present. The line voltage current drawn by the power supply module will
be approximately half the DC output. For example, for a 4 amp power supply, the line voltage
service should be able to supply at least 2 amps. Note: if the suffix “H” appears in the part
number (i.e. BPSMH-24-4), the unit requires 220 VAC input. Apart from this change, all other
characteristics are the same.
3.2 DC OUTPUT
The maximum DC output of the power supply is expressed by the final figure in the part
number. The BPSM-24-4 can supply up to 4 amps; the BPSM-12-6, up to 6 amps etc. However,
these power supplies are adjustable and the voltage level set affects the current output capacity.
When used with batteries, the power supplies must be set at 12.5% over voltage (13.5 V for
12 volt supplies and 27 V for 24 volt supplies). This is the factory setting and if the voltage is
to be changed, use the potentiometer marked "V Adj" on the power supply module. The current
rating takes into account the possibility of the supplies operating at 12.5% over voltage.
