CERBERUS PYROTRONICS PS-35S Power Supply
Description
The Cerberus Pyrotronics Power Supply Model PS-35S is a step-down transformer and bridge designed for use with Control Panel Model CP-35 and to provide power for regulated pre-action releasing service. The units, which are modularized for System 3 enclosure mounting, are of deadfront construction and contain terminal strips, a circuit breaker with a reset switch on the AC input, protection fuses on the DC outputs and a receptacle for jumper plug connection directly into the control Panel Model CP-35. This equipment is approved for operation over the temperature range of 0°C to 49°C.
Operation
The Model PS-35S provides a rectified, full wave 24 VDC output from an input supply of 120 VAC, 50/60 Hz. The input consists of a main power phase and a trouble phase, each separately fused, and a common neutral. The 24 volt full wave output is rated at 10 Amps DC, full load. When the PS-35S is used to power the control panel system, the second output (terminals 5 and 6, rated at 24 VDC 2 Amps, bridge only) is used to power RM-30U/RU modules through a DC- 35S regulator and a TC-30U transfer module for releasing pre-action or deluge valves. This module combination is approved by FM for this application. Surge protection is provided across both the input phases as well as the DC output.
Engineer and Architect Specifications
The power supply for the alarm system shall be a Cerberus Pyrotronics Model PS-35S. This unit shall be Underwriters Laboratories Inc. listed. The unit shall provide a full wave of rectified 24 VDC output rated at 10 Amps full load. The PS-35S shall be capable of powering 100 detection zones (50 ZU-35 Zone Modules and 4 fully loaded Alarm Extender Modules Model AE-30U simultaneously.) The rated output, which shall be completely fused, shall be provided at a plug receptacle. A second output (terminals 5 and 6, rated at 24 VDC 2 Amps bridge only) is used to power modules internally housed and wired within the control unit enclosure. The power supply shall be of a deadfront construction and housed in a steel enclosure compatible with the modularized alarm system. Externally mounted 120 VAC/24 VDC transformers shall not meet the intent of this specification.

Electrical Ratings
PS-35S Power Requirement: 120 VAC, 50/60Hz, three wire. 3.5A Max
The Model PS-35S with the CP-35 Control Panel occupies space normally taken by 8 modules. The power supply for the CP-35 must be mounted in the upper right- hand position of a System 3 enclosure. This should be considered when sizing the enclosure. Additional power supplies, if required, are mounted adjacent to the modules to be powered by them.
