SILENT KNIGHT FIRE ALARM ACCESSORY Model 5295 Signal Power Expander FEATURES _i · Adds More Signal Power to Local Fire Controls · Aids Compliance with ADA Require- ments Using Existing Local Control' · UL Listed for Alarm Signal Circuits · Two Supervised Inputs · Four Style W (Class B) Signal Circuits · Highly Efficient Switching Power Supply (24 VDC at 6 Amps) · 10 to 30 Volt Activation · Fuseless Design · Compatible With Most Manufacturers' Local Controls The Model 5295 Signal Power Expander provides additional supervised circuit capacity for local fire alarm systems, This makes the Model 5295 a very cost-effective solution to meeting tough Americans with Disabilities Act (ADA) requirements, The 5295 increases the signaling power available for the addi- tional sounders and the brighter strobes called for by the ADA, Meeting those requirements is easily accomplished in a retrofit or new installation, DESCRIPTION The 5295 is a 24 volt 6 amp switching type power supply housed in its own red cabinet. It contains an integral precision battery charger capable of charg- ing two 12 volt 6.5 amp hour batteries. The cabinet provides ample room for field wiring and standby batteries, ~ -3' CONNECTION TO LOCAL FIRE CONTROL The 5295 can be connected to a local fire control which utilizes polarity reversing Style W (Class B) type signal circuits operating between 9 and 32 volts DC, The local control signal circuit is connected to one of the inputs on the 5295, The local control's signal circuit end-of-line resistor is also connected across two terminals on the 5295, which provides supervision between the 5295 and local fire control. Polarized audible and/or visual indicating devices are then connected to the 5295 signal circuits using , the 4,7K ohm end-ot-Iine resistors provided. A mov- able shunt block allows selecting whether all four signal circuits on the 5295, are activated by a single input from the local control, or whether each input activates two signal circuits, Since the 5295 draws very little power trom the local control, it is possible to connect one 5295 to each signal circuit, on the local control. and still provide tull supervision ot the signal circuits all the way back to the local control. . SUPERVISION LOW AC, When a Low AC condition (102 VAC or less) is detected, the green AC POWER indicator will turn off, It Low AC is detected for longer than 6 hours, the 5295 will open the Signal 1 and Signal 2 input loops, causing the local control to go into trou- ble, These conditions will restore when AC returns to 108 V AC or higher, LOW BATTERY, When a Low Battery condition, 20.4 VDC or less, is detected, the yellow BATTERY indicator will turn on and the 5295 will open the Signal 1 and Signal 2 input loops causing the local
