WHAT MAKES A GOOD FIRE ALARM INSTALLATION

Review of spec if availableReview of drawings if availableReview of the operation if available (specifically for retrofit applications)Understanding the equipment you are installingUnderstanding the requirements for the VerificationUnderstanding wiring practices such as polarities, isolators, signal loading, metering of wires, voltage drop.Programming information such as operations, preactions/releasing systems, relays and descriptors

WHAT MAKES A GOOD FIRE ALARM INSTALLATION

TYPE OF WIRE REQUIREDLOADING CALCULATIONS – how many signals per circuit/Voltage drop.NO SPLICES – this causes problems. Wire device to deviceProper in and out device terminals

3.3.1.3 In Class A circuit wiring, data communication link Style A and data communication link style C wiring, the primary wiring circuit and the alternate wiring circuit shall be installed in separate raceways or cable assemblies having a minimum separation of 300 mm where cables are installed vertically and 1200 mm where the cables are installed horizontally, except under the following conditions:

CAN/ULC-S524-06Standard for Installation

13

3.3.1.3 cont.A: For a distance not to exceed 3000 mm where the primary and return conductors enter or exit the field devices, control unit or transponder enclosuresB: Single conduit/raceway drops to individual field devices or,C: Single conduit/raceway drops to multiple field devices installed within a single room not exceeding 100m2

ISOLATORSULC-S524-06

New Data Circuit Isolator Requirements Added survivability during a fire Isolators required on both sides of a fire separation, offset horizontally and in different stud channel Waterflow or duct smokes mounted in one area but serving different floors or zones are consider same area and do not require isolator separation Isolators required on floor side only when picking up a single device in an exit or vertical shaft. (two modules, 1 in & 1 out)

What is an Isolator?Isolators provide short circuit protection between “floor areas” or fire zones so that a short circuit fault in one area does not affect normal operation in another area.

Hardwired systems• Isolators not required since separate zones

were on separate wires

Addressable systems• Devices from more than one zone are often

connected on the same pair of wires

4.2.7 Where a data communication link utilizing active field devices or supporting field device serves more than one National Building Code of Canada required fire alarm zone, a fault within on fire alarm zone shall not prevent the normal operation of other input or output field devices in another fire alarm zone, except as noted in Clause 4.2.8


22

5.14.5 Where a fire separation is provided, fault isolation modules required by Clause 5.14.2 shall be installed on each side of that fire separation.


23

CAN/ULC S 524-06 5.14 Fault Isolation Modules5.14.1 This Subsection

applies to the installation of fault isolation modules as required by Clause 4.2.10.

Note: Where available, fault isolation modules should be in a fire separated electrical room.


24

5.14.2 "Fault isolation modules shall be utilized when entering and leaving each fire alarm zone, as required by the National Building Code of Canada" Cont…


25

5.14.2 CONT…Note: Clause 5.14.2 is intended to

apply to the field devices located within the areas described above, which may include field devices monitoring mechanical equipment servicing other floor areas. For example, water flow devices on sprinkler systems or duct type detectors on HVAC systems serving other floors or areas are considered part of the same area specified in Clause 5.14.2 and need not be seperately fault isolated.


26

5.14.6 Fault isolation modules installed on opposite sides of same fire separation shall be offset horizontally to a minimum of 400 mm, and not located within the same stud space.


30

5.14.8 Fault Isolation modules serving a single field device in an exit of vertical service space shall be installed on the floor area side.

Note: Fault isolation modules are not required on the exit or vertical service space side.


31

5.14.9 "Fault isolation modules shall have an identifying mark or label on the cover plate or field device. The identifier shall be visible after installation. Where field devices incorporating fault isolation modules are used to comply with Clause 5.14.2 the first device entering and the last field device leaving each fire alarm zone shall be marked."

3.4.13 When using shielded cable, the shield shall be continuous and isolated from ground through all junction boxes. The shield shall be bonded in accordance with the manufacturers instructions.Note: The reason for this requirement is to prevent multiple ground loops that can disrupt proper system communications. At no time shall shields of specific groups of cables be common connected.


39

3.4.15 "Ancillary circuits shall not be used to activate circuits of a voltage level greater than 30V directly within the control unit and transponder. Multiple voltage relays or devices, mounted external to the control unit or transponder shall be utilized."


40

3.5.2 The plans of the building shall show the fire alarm zoning, device address, and the location of each field device of the fire alarm system, including fault isolation modules, ancillary devices, and annunciators, or display and control centres".

ABC 3.2.4.18.(13) cont…a) the automatic signal silence cannot

occur within the first 60 seconds of operation or thin the zone in initiation,

b) a subsequent alarm elsewhere in the building, will reactuate the silenced audible signal devices within dwelling units,

c) after a period of not more than 10 min, the silenced audible signal devices will be restored to the continuous audible signal if the alarm is not acknowledged, and

5.7.4.2 Cont….Note: In areas with high ceilings (eg. Atriums)

beam type smoke detectors or aspiration detectors should be considered to provide better maintenance and testing access. Data is not available for ceilings higher than 9000mm, therefore, in such installations, fire type, growth rate, engineering judgement and manufacturers recommendations should be used.
