1.0 INTRODUCTION
1.1 System Overview
•
Under ULC-S527, the FIRE-LINK system is an
accessory
to an existing fire alarm system.
•
Under UL 985 and ULC-S545, the FIRE-LINK system is a
stand alone system
.
•
The intended use is to readily increase fire alarm audibility in suites and living quarters without the addition of
any new extensive wiring.
•
The system, when configured as an accessory, is
NOT
for fire detection and no devices should be installed!
•
The FIRE-LINK system uses a proprietary power line communications protocol to communicate between
various FIRE-LINK devices using the existing 120VAC power line wiring.
•
The primary components of the FIRE-LINK system include:
o
the
Network Monitoring Controller (NMC),
o
the
Passive Phase Coupler (PPC)
o
and at least one (1)
In-suite Signaling Device (ISD).
The
NMC
is the main controller of the system network.
•
It communicates with each uniquely addressed ISD device installed on the system.
•
It receives the alarm signal from the existing FAC Panel and sends the alarm signal to each
of the
ISD
units via the power line. Up to
253
ISD units can be installed on any given network
(based on optimal conditions). However,
100
ISDs is the recommended limit for typical
building installs because of building attenuation and electrical distribution profile. Power line
conditions will vary building to building whether there are 10 or 250 suites in the building.
The NMC is in constant communications with all of the ISD units. Under normal conditions, the NMC interrogates
each ISD for status. A trouble condition occurs on the NMC if any ISD is unplugged and loses communication or
has low or missing battery power. If a fire alarm condition occurs, the NMC sends a broadcast alarm signal to
each ISD putting all ISDs into alarm mode, thus sounding their piezo.
The purpose of the
PPC
is to couple the communication signals between the different phases of the buildings
electrical wiring as the signals will not go through transformers.
Important Notice:
The piezo on the NMC is for local annunciation ONLY and is not intended for alarm
notification purposes. Alarm notification is provided by the ISDs.
1.2 System Set Up
The NMC can be configured in one of two ways
:
1.
Master Mode
or
2.
Slave Mode
(Specified in Canada).
One of the primary differences is the way the alarms are managed.
1. In
Master Mode,
the
NMC
acts as a
stand-alone
unit in that it receives the alarm signals from and sends
trouble signals to the Fire Alarm Control Panel (FACP) but the FACP has no other control of the operation
of the NMC. The NMC receives the alarm signal from the FACP dry alarm contact. In this mode, ‘Alarm
Silence’ must be initiated on the NMC to silence the ISDs regardless of any action taken on the FACP.
This method will utilize one of the two alarm zones on the NMC for the alarm triggering.
2. In
Slave Mode,
the NMC is driven by the on-board
Bell Output Relay
tied into any
SPARE
Supervised
Signal Circuit of the FACP. In this mode, if an ‘Alarm Silence’ is initiated on the FACP, it will cause the
NMC to also silence all the ISD units. No reset action is required on the NMC.
