FIRE
ALARM SYSTEMS:
Building
fire alarm systems usually consist of a common control (mounted
in a metal box), manual pull stations at every exit door, smoke
detectors in the hallways, and some means of audibly and/or visually
notifying the occupants of the buildling that an alarm has occurred.
The audible signals can consist of bells or buzzers, but in some
systems, an alarm tone is generated through a series of speakers
located on each floor of the premise. Where hearing impaired patients
or occupants are located, it is usual to have strobe lights located
along corridors and in individual rooms that indicate a fire exists
in the building.
The
common control employs several features to enable the occupants
to identify problems within the system. Correction of any troubles
should be left in the hands of a fire alarm service company. Most
fire alarm systems employ "zoned" annunciators so that
fire fighting personnel can be dispatched to the proper area of
the building.
There
are several different manufactures of building fire and evacuation
type systems. Here are a few of the more common ones. We've provided
links to some of the manufacturers so you can investigate their
equipment and services.
Daily
Testing -
is the responsibility of the building management or an individual
they've designated to perform these duties. They include:
- Checking
to ensure that there is no large accumulation of combustible
material, rubbish or flammable liquids;
- Checking
to ensure that all the exit signs are in good order, and that
adequiate lighting in the public corridors and stairwells is
maintained;
- Checking
to ensure all the fire doors operate properly and that none
are wedged in the "OPEN" position;
- Checking
all the exit routes remain free from obstructions;
- Checking
to ensure all fire hoses and extinguishers are unobstructed,
in good order and ready to use;
- Checking
the fire alarm control panel to ensure it is free of obstructions,
any glass panelling is clean, the locks have not been tampered
with, the "AC POWER" indicator is "ON",
and that the system is trouble free;
- Checking
corridor and public area fire and smoke detectors, pull stations,
audible and visual appliances (bells, horns) to ensure they
are clean, undamaged, and unobstructed.
Monthly
Testing -
Requires the building management or designated individual to actually
initiate a fire alarm by activating one of the building's pull
stations. You can download the monthly test record in either Word
or WordPerfect
format. It's usually a good idea to post the date and time of
the test so that tenants/occupants are aware of the situation
and won't be unduly alarmed. It might be a good idea to suggest
that they practice their individual escape plans during the test.
The montly test is to ensure that all audible and visual alarm
indicators function properly and are loud (or visible) enough
to alert all the occupants to a fire condition.
In
addition to this test, the designated individual should also ensure
that he responds to issues and concerns expressed to him by the
tenants/occupants with regard to the operation of the fire alarm
system.
Annual
Testing
- The Annual Test of the fire alarm system is performed by qualified
technical personnel to a specific standard called ULC CAN4-S536
(Standard for the Testing of Fire Alarm Systems). There are a
number of companies in the Lower Mainland that perform this service.
In some municipalities (Vancouver, Richmond, and Langley), the
individuals performing the test must be certified by A.S.T.T.B.C.
The test report must be submitted to the building owner's representative
in a format approved by the local authority.
The
Verification
- Verification of a fire alarm system must take place when the
system is first commissioned and is one of the final steps to
obtaining an occupancy permit for the building. The test is performed
to ULC CAN-S537-97 (Standard for the Verification of Fire Alarm
Systems) by the fire alarm system manufacturer, or an individual
authorized by the manufacturer to perform the service. In some
instances, the Electrical Design Engineer is involved in the process
as well. This is the most rigorous of testing procedures the system
will have to undergo in it's lifetime. Not only are individual
devices tested for a variety of conditions (not just operation),
each device in the system must be examined for proper "PLACEMENT".
This ensures the pull station/smoke detector/heat detector/bell
is installed in accordance with the manufacturer's instructions,
the applicable building codes/bylaws, and ULC CAN-S524 (The Standard
for Installation of Fire Alarm Systems).
In
addition, a verification may be required if a device is replaced
or added to the system. Please check with your local civic authority
(Electrical Inspections or Planning) and follow their guidelines
to ensure compliance of your system.
Anubis
Systems Technologies is a full service agency
providing complete verification services as well as
troubleshooting/repair for most major fire alarm systems.
We are approved to perform verifications in all
l ower mainland jurisdictions. For more information

SMOKE
DETECTORS
Smoke
and fire detectors should be considered an integral part of any
home or business security system. In most all instances involving
fire, a smoke detector provides sufficient warning to the residents/occupants
to enable them to evacuate the premises safely, notify the fire
department, and minimize the damage to the structure and contents.
A security or fire alarm system that employs integrated smoke
detectors is by far the best way to protect your family or workers.
In this instance the detectors are powered by a stand-by battery
that will ensure continued protection even in the complete absence
of electrical power or a "brown-out". Smoke alarms that are battery
operated should have the batteries replaced every six months.
It's a good idea to mark the replacement date on a piece of masking
tape and stick it onto the body of the detector. Use only
alkaline or lithium type batteries and make sure you double check
the expiry date on the battery and test it before you place it
in the unit. Most smoke detectors installed today are wired
directly to the household electrical system. These units
are vulnerable to electrical failures (they won't function in
the absence of power). Most house fires start in the electrical
wiring so it's a good idea to have a battery operated smoke alarm
installed as a "back-up". There are two types of smoke detectors
(alarms):
Ionization
type smoke detectors utilize a small source of radioactive
material (usually Americium) that in fact ionizes airborne particulates
and attracts them to to one side or the other of a polarized grid.
When sufficient particles accumulate, the unit goes into an alarm
condition. This type of detector works best for fast flaming fires
that produce small amounts of smoke. It's also prone to false
alarms when installed close to bathrooms or kitchens with older
style dishwashers. Steam from your hot bath, shower, or operating
dishwasher may accidentally "set-off" one of these units). It
SHOULD
NOT
be used in a residential application as most home fires involve
intense smoke.
Notice to users of Ionization type
detectors - these sensors have a limited life of between
ten and fifteen years. Check the date stamp located on the back
of the detector. If in doubt, replace the unit and dispose of
the old one in a safe manner.
Photoelectric
type smoke detectors utilize an infrared light source (called
the emitter) and a receiver, both of which are located inside
the sensing chamber. Smoke particles obscure the receiver, and
the unit goes into alarm. This type of detector is best used in
residential applications, as it provides extremely good early
warning to smoldering type fires that tend give off dense smoke
and noxious fumes.
Regardless
of the type of detector your residence or building employs, there's
some additional maintenance you can perform to ensure the continued
peak efficiency. Once a month or so, take your vacuum (on it's
lowest setting) and utilizing a soft brush attachment, clean out
the vents of the detector. Never paint the
sensor! If the sensor is part of an actual fire alarm system,
make sure you alert other tenants in the building as to what you're
doing as well as your monitoring station (if applicable). There
is a possiblility that you may inadvertenly set off the fire alarm
system. Have someone standing by the panel so that they can cancel
any alarm quickly.
