Module 4
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
Terminology
Conventional Distributed Power Supply
Conventional power supply
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
Synchronization refers to the alarm visual
appliances and making them flash at the same
rate, or in synchronization
NFPA 72
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

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
