Course Objectives At the end of this course you will be able to: Explain the advantages of Conventional Distributed power supplies Explain the advantages of intelligent power supplies Demonstrate how to synchronize strobes using power supplies Describe how to use both intelligent and Conventional Distributed power supplies effectively in the same system
Conventional Distributed Power Supply Conventional power supply Terminology Used to expand power and distribute it throughout a system Intelligent Power Supply Uses unique identification that can both report status and control other devices
Synchronization refers to the alarm visual appliances and making them flash at the same rate, or in synchronization NFPA 72 Synchronization Requires visual appliances to flash in synchronization Rooms or areas where there are two or more visual devices If less than 55 feet apart Flash within 10 mil seconds
Switching vs. Linear Design Switching power supply s are used in computers Up to 50% more efficient Puts out less damaging heat Faster input re-action Gives you lighter weight LOWER SHIPPING COSTS!!
Current Requirements Current Draw From Host FACP See manufacture s specification sheets to determine current draw from FACP Current Draw From Batteries Each power supply must have its own battery calculation Use the Battery Calc at www.silentknight.com for best results
Review True or False: NFPA requires all strobes to be synchronized? False, only in rooms or areas where there are two or more visual devices
Conventional Distributed Power Supplies Will work with any supervised NAC Most cost-effective solution for additional power Easy to Sync Silent Knight Advantages Has separate Aux power source so you don t lose 2 NAC outputs to gain Aux output Can use SK control module to supervise the trouble without a separate monitor module
Conventional Distributed Power Modules 6 Amps! 9 Amps! Model 5495 Model 5499
Conventional Distributed Power Modules 3 Amps per output 4 Notification outputs 1 Aux output Fuseless design Dip switch programmable Unique feature! Sets Silent Knight Apart!
Conventional Distributed Power Modules Fully Supervised Flexible wiring Class A or Class B 2 Input circuits Activated and supervised by FACP Built-in Synchronization Amseco Faraday Gentex System Sensor Wheelock
Conventional Distributed Board Example SK 5495
Conventional Distributed Board Example Dipswitch for selecting options SK 5495
Dipswitches 1,2,3 Configure inputs 1 & 2 Select class A or class B Dipswitch 4 Dipswitch Options Delay / no delay on loss of AC Delay = delays reporting for 6 hours No delay = instant alarm Dipswitch 5 Controls Aux output Is it on or off during loss of AC
Dipswitches 6,7 Controls Sync Wheelock System Sensor Faraday Amseco Gentex Dipswitch Options
Conventional Distributed Board Example Only the green AC LED should be on in a normal condition Rest will light up yellow in a trouble situation SK 5495
Conventional Distributed Board Example 4 Conventional NACs 1 Aux 1 Trouble relay Inputs for any supervised NAC
Signal Input Terminals Class B wiring from a FACP Alarm Condition (ON) The power supplies will accurately sense the polarity of the FACPs notification circuit to drive the outputs Whether or not the supervision connection is intact During the Alarm Condition (ON) FACP will not sense trouble conditions though its notification circuits
Signal Input Terminals Trouble relay does NOT have to be monitored Class B wiring from a FACP The FACP supervises its notification output the same way it supervises ordinary notification circuits Open circuit = trouble The power supplies emulates the trouble behavior by breaking the EOL supervision current for any power supply trouble Putting the FACP into a notification circuit trouble
Notification Power Class A wiring from a FACP
Notification Power Class B wiring from a FACP 2-4 MS delay Signal OUTPUT 1 Signal OUTPUT 2 (optional) 120 VAC Signal 1 Signal 2 Signal 3 Signal 4 Aux Power Any FACP Conventional Distributed Power Supply The synchronized signal sent into the power supply will be the same sent out

All Conventional Distributed Power Supply s outputs will follow the synchronized input FACP - + NAC
Advantages Easy to do if panels are in the same room All NAC circuits turn on at the same time All power supplies sync off the FACP No additional hardware needed
Conventional Distributable Power Supplies Any FACP Take an out to power as many Conventional Distributed Power Supplies as you want
Disadvantages Cannot turn off selected zones If trouble shows up on any power supply, it will show up as NAC trouble on FACP Does NOT tell you where trouble is
