PS904 4 AMP POWER SUPPLY WITH 900-4RFA BOARD
The SCHLAGE PS9044RFA, PS904 4 AMP POWER SUPPLY WITH 900-4RFA BOARD includes the following features:
Designed for fire alarm applications, the PS904 electronics control unit provides fire alarm signaling functions. With an output of 4 Amps and 900-4RFA board, the PS904 is intended as a power source for types 1, 2 and 3 initiating devices (microswitch, manual station, manual pull station, water flow switch). The PS904 may also be used to supply power to a variety of other fire alarm circuits.
Schlage Electronics' PS9044RFA 4 Amp Power Supply with 900-4RFA Fire Alarm Interface Board and 120/240VAC at 50/60 Hz Input -- includes (4) Relay Output Boards
A solid foundation to our industry-leading Alarm Monitoring System. This 4-Amp, 120/240VAC to 12VDC power supply can be used at the same time as a 1 Amp or 3 Amp power supply. The 900-4RFA board includes four optically isolated relays that are controlled by the PS904 alarm panel via its auxiliary outputs. An ideal complement to the 225 and 335 Series alarm systems
A 4 amp power supply with a 900-4rFA board included. This power supply has terminals, that you can use for driving the fire alarm interface board, which looks like two light bulbs connected vertically to the board. The radio controlled clocks are 24 volt devices, but they can be driven by 120/240v ac from the input of this power supply. The non-radio controlled clocks are 120/240 volt devices that require a 24 v ac sine wave output. The sine wave output is made on the UL listed single phase bridge rectifier and the capacitor filter.
The PS904 addresses the needs of fire alarm controllers where a continuous power source is required. The standard 904-4RFA board contains 4 SPDT solid state relays. Relay outputs are selectable as Normally Closed (NC) or Normally Open (NO).
Power supply. 4 amp maximum continuous current. 12/24 volt output. 120/240 volt input at 50 to 60 Hz. Includes four programmable relays and fire alarm interface board 900-4RFA.
