Siemens PSC-12 12 Amp Power Supply, Installation Instructions

Installation Instructions PSC 12 Amp Power Supply Model PSC 12 from Siemens Industry Inc is a high current power supply that the FireFinder XLS Desigo Fire Safety Modular Cerberus PRO Modular with primary regulated 24VDC It is rated at 12A and has a built in charger that capable of charging up to batteries It also has a circuit that allows PSC 12 to switch the power to stand by during loss or of the AC PSC 12 incorporates 18A circuit breaker on battery input It connection to a switch and tie points for signals 1 12 Amp Power Supply PSC 12 communi directly to the PMI XLS Desigo Safety Modular Cerberus Modular to report fault conditions and allows the PMI PMI 2 PMI 3 XLS Desigo Fire Safety Modular FCM2041 U3 Cerberus PRO Modular to the status of the power supply It has 1 common alarm relay 1 common relay and 2 programmable relays The common alarm and common trouble are defaulted to activate when the degrade ALARM bus or degrade TROUBLE is asserted PSC 12 mounts at the back of the enclosure of the FireFinder XLS Desigo Fire Modular Cerberus PRO Modular system and occupies one location on the in the backbox or on the optional FireFinder XLS Desigo Fire Safety Modular PRO Modular Mounting Plate CAB MP PSC 12 features are as follows power input 120VAC 240VAC 10 60Hz 50Hz Switch Mode Power Converter Factor Correction Battery Charger Output power of 12A 24VDC 315 033060

Supply and the Interface Board separate power output terminals one power limited terminal with 4A 24VDC capacity and one non power limited terminal with 12A max 24VDC capacity total not to exceed 12A output terminals have current measurement capability resettable current protection circuits for overload and short circuit to CC 5 CC 2 System bus 6.2VDC 2A power limited to the system bus 24VDC 2A power limited to the system bus subject to a 12A current limit via HNET protocol termination for the tamper switch common alarm relay one common trouble relay and two program relays with 2A ratings Controller determines the activation of the Charger and monitors the status of Power Supply ground fault conditions loss of network communication 24VDC overload and the status of the battery This information is relayed to the Interface where applicable and is communicated to the PMI PMI 2 PMI 3 FCM2041 U2 Desigo Fire Safety Modular FCM2041 U3 Cerberus PRO for system reporting The Controller also allows the PMI PMI 2 PMI 3 XLS Desigo Fire Safety Modular FCM2041 U3 Cerberus PRO Modular to the state of the power supply and its current load and can send a diagnostics to the PSC 12 It also provides the control of the relays degrade ALARM bus and degrade TROUBLE bus will override the command that sent by the PMI PMI 2 PMI 3 XLS FCM2041 U2 Desigo Fire Safety Modular Cerberus PRO Modular to the Alarm and Trouble relays Power Supply has an Off line switch mode power converter and power factor circuit to improve conductive RF emission at low frequency It is designed take voltage inputs of 120VAC 240VAC at 60Hz 50Hz and has one resettable breaker that can also be used as a battery power switch Charger monitors and maintains the battery This circuitry utilizes three charge depending upon the state of the batteries Bulk Full Charge State Trickle State and Float maintenance State The Charger monitors the batteries and which of the charging modes to activate It also has the capability to the state of the battery through diagnostic testing Interface Board provides diagnostics LEDs system connections and the terminal on the PSC 12 Blocks and Indicators PSC 12 has one reset switch seven LEDs three HNET CAN address switches circuit breaker four terminal blocks four terminal connections and two 60 pin flat connections as shown in Figure 2 reset switch is located on the top of the front panel Pushing the reset switch re the PSC 12 operation Industry Inc Technologies Division 315 033060 19 LEDs located at the top left of the module and are as follows FAIL FAIL FAIL FAULT 12A FAIL 4A FAIL ON When illumi indicates that the PSC 12 is from the AC mains When indicates that the PSC 12 is from the battery OFF When illumi indicates that the module micropro has failed OFF When illumi indicates that CAN communica with the PSC 12 has terminated only when PSC 12 resides in CAN network OFF When illumi indicates that the HNET communi with the PSC 12 has terminated and PSC 12 goes to degrade mode only when the card resides in HNET network OFF When illumi indicates that the PSC 12 has either a negative or positive fault on its outputs OFF When illumi indicates that the 24VDC non limited output has a trouble or the PSC 12 has disconnected 24VDC output due to current overload short circuit OFF When illumi indicates that the 24VDC power output has a trouble condition or PSC 12 has disconnected the 24VDC output due to current overload or circuit and negative ground fault detected at ohms for TB3 terminals 1,2 ohms for TB4 terminals 1,2 ohms for TB1 terminals 10,11 ohms for TB1 terminals 4,5,7,8 ohms for TB1 terminals 1,2 2 Blocks Controls and Indicators rotary dial switches located directly below the LEDs are used to set the HNET network address of the PSC 12 terminal blocks of the PSC 12 are defined as follows See Figures 2 3 and 4 1 2 and 3 provide connection to the FMT riser 4 5 and 6 provide an output to the monitor speaker in a mounted LVM 7 8 and 9

external CAN network connection All are not used outputs 1 for Alarm 1 for Trouble and 2 User programmable relays are set to NOT USED by default These outputs are rated 2A 30VDC 6 PF normal system operation the alarm and trouble relays are by the PMI PMI 2 PMI 3 XLS FCM2041 U2 Desigo Fire Modular FCM2041 U3 Cerberus PRO Modular However if the fails and the initiating card cannot communicate with the PMI XLS FCM2041 U2 Desigo Fire Safety Modular Cerberus PRO Modular the DLC will control the ALARM TROUBLE relays The User programmable relays are activated by the XLS FCM2041 U2 Desigo Fire Safety Modular Cerberus PRO Modular output logic as programmed by Zeus tool When the system is operating normally these relays are by the output logic only See Figure 4 Power Limited Output Terminal This terminal output is limited to When it is exceeded it will shut down light its associated diagnos LED and send a fault condition to the PMI PMI 2 PMI 3 XLS Desigo Fire Safety Modular FCM2041 U3 Cerberus PRO output is normally connected to the modules and cards located on door of the enclosure or to remote CAN network modules This is power limited to NFPA 70 per 760 All wiring must be in with
