Model PSC-12
12 Amp Power Supply
INTRODUCTION
Features
P/N 315-033060-19
The Model PSC-12 from Siemens Industry, Inc., is a high current power supply that
provides the FireFinder-XLS/Desigo Fire Safety Modular/Cerberus PRO Modular
system with primary regulated 24VDC. It is rated at 12A and has a built-in charger that
is capable of charging up to
100AH batteries. It also has a
microprocessor-controlled
transfer circuit that allows
the PSC-12 to switch the
system power to stand-by
batteries during loss or
reduction of the AC
power.
The PSC-12 incorporates
a 18A circuit breaker on
the battery input. It
provides connection to a
tamper switch and
terminal tie points for
system signals.
The PSC-12 communi-
cates directly to the PMI/
PMI-2/PMI-3 (XLS),
FCM2041-U2 (Desigo
Fire Safety Modular),
FCM2041-U3 (Cerberus
PRO Modular) to report fault conditions and allows the PMI/PMI-2/PMI-3 (XLS),
FCM2041-U2 (Desigo Fire Safety Modular), FCM2041-U3 (Cerberus PRO Modular) to
query the status of the power supply. It has 1 common alarm relay, 1 common
trouble relay, and 2 programmable relays. The common alarm and common trouble
relays are defaulted to activate when the degrade ALARM bus or degrade TROUBLE
bus is asserted.
The PSC-12 mounts at the back of the enclosure of the FireFinder-XLS/Desigo Fire
Safety Modular/Cerberus PRO Modular system and occupies one location on the
studs in the backbox or on the optional FireFinder-XLS/Desigo Fire Safety Modular/
Cerberus PRO Modular Mounting Plate, CAB-MP .
The PSC-12 features are as follows:
•
AC power input 120VAC - 240VAC +/- 10% @ 60Hz / 50Hz
•
Off-line Switch Mode Power Converter
•
Power Factor Correction
•
Built-in Battery Charger
•
Total Output power of 12A@24VDC

12 Amp Power Supply INTRODUCTION The Model PSC-12 from Siemens Industry, Inc., is a high current power supply that provides the FireFinder-XLS/Desigo Fire Safety Modular/Cerberus PRO Modular system with primary regulated 24VDC. It is rated at 12A and has a built-in charger that is capable of charging up to 100AH batteries. -
Page 2: Operation
2A ratings OPERATION The PSC-12 occupies one network address in the HNET network and has four functional components: the Controller, the Charger, the Power Supply and the Interface Board. The Controller determines the activation of the Charger and monitors the status of the Power Supply (ground fault conditions, loss of network communication, 24VDC terminal overload and the status of the battery). - Page 3 Three rotary dial switches located directly below the LEDs are used to set the HNET/ CAN network address of the PSC-12. The terminal blocks of the PSC-12 are defined as follows (See Figures 2, 3 and 4): Terminals 1, 2 and 3 provide connection to the FMT riser.
- Page 4 TB4-2: (-) terminal The total cumulative sum of the 24VDC output (power limited + non-power limited) must not exceed 12A. Over current draw will initiate a PSC-12 shut down. The main AC power line must be turned OFF prior to installation.

Contains a factory installed plug. Do not remove the plug from P4. This plug must be installed at all times to allow the charger section of the PSC-12 to properly control the battery charging process. Connects the HTSW-1 Tamper Switch to the PSC-12 to determine the position of the panel door. -
Page 6: Installation
The following components must be set prior installing the module in the enclosure: Verify that the dedicated circuit breaker for the PSC-12 is turned OFF at the mains. • Battery Circuit Breaker: Set this circuit breaker to the OFF position. - Page 7 Mounting The PSC-12 On The Optional CAB-MP WIRING The PSC-12 has removable terminal blocks and connectors at the top and bottom of the module. The terminals and connectors at the top of the PSC-12 are power limited. The terminals and connectors at the bottom of the PSC-12 are non-power limited.
