Smoke alarms or smoke detectors have saved
thousands of lives. Thanks to most local fire departments most homes and
businesses now require smoke alarms. Smoke detectors are a powerful and
effective fire safety technology. They are the first lines of defence
against smoke and fire. They may awaken those who would otherwise have
been overcome by smoke and toxic gases in their sleep. And most
importantly, they provide an early warning alerting individuals of a fire,
allowing them precious time to escape.
All smoke
alarms should be replaced after 10 years of operation
( 10 years is a
smoke alarm's useful lifetime for continued, reliable safety and
protection) and be tested regularly.
By providing an early warning in the event of fire, smoke detectors may allow you
and your family sufficient time to reach safety. UL offers the following tips for
purchasing and maintaining smoke detectors:
When purchasing a smoke detector, look for the UL Mark on the product as well as on
the packaging.
Install UL Listed smoke detectors outside each bedroom and sleeping area and on
each additional level of your home -- including the basement.
When installing your smoke detectors, read and follow the manufacturer's
instructions exactly. If you need any additional information or advice, contact your local
fire department for assistance.
To keep them in good working order, test, clean and maintain your smoke detectors
as instructed in the owner's manual. Testing also familiarizes you and your family with
your units' alarms, helping you to recognize their emergency signals. Cleaning helps
eliminate dust that collects on smoke detectors and causes false alarms.
Typically, battery-operated detectors should be tested every week; detectors wired
into your home's electrical system should be tested monthly.
Replace the batteries in your battery-operated smoke detectors at least once a
year.
Ionization smoke detectors monitor 'ions,' or electrically charged
particles in the air. Air molecules in a sample chamber of ionization
smoke detectors, are 'ionized' by a radioactive source. This allows a
small electrical current flow. Smoke particles entering the sensing
chamber change the electrical balance of the air. The greater the amount
of smoke, the higher the electrical imbalance. When combustion particles
enter the smoke detector, they obstruct the flow of the current. An alarm
is pre-programmed to sound when the current gets too low.
Ionization smoke detectors respond first to fast flaming fires. A flaming
fire devours combustibles extremely fast, spreads rapidly and generates
considerable heat with little smoke. Ionization alarms are best suited for rooms, which contain highly
combustible material.
Photoelectric smoke detectors respond first to slow
smouldering fires. A smouldering fire generates large amounts of thick,
black smoke with little heat and may smoulder for hours before bursting
into flames. Photoelectric models are best suited for living rooms, bedrooms
and kitchens. This is because these rooms often contain large
pieces of furniture, such as sofas, chairs, mattresses, counter tops, etc.
which will burn slowly and create more smouldering smoke than flames.
Photoelectric smoke alarms are also less prone to nuisance alarms in the
kitchen area than ionization smoke alarms.
The use of both ionization and photoelectric smoke alarms will provide a
home with maximum protection and an ample warning in the event of a fire.
Locations for Smoke Alarms:
• On every level of your home, including finished
attics and basements.
• Inside every bedroom, especially if people sleep with the door
partly or completely closed.
• In the hall near every sleeping area. If your home has multiple
sleeping areas, install a unit in each. If a hall is more than 12
meters (40 feet long), install a unit at each end.
• At the top of the first-to-second floor stairway, and at the bottom
Because smoke rises, smoke alarms should be installed on the ceiling or on
walls at 4 to 6 inches below the ceiling. Smoke alarms should not be
located less than 4 to 6 inches from where the wall and ceiling meet on
either surface; this space is dead air that receives little circulation.
The Meridian photoelectric smoke detector sets a
standard for reliability and performance, with a chamber so
revolutionary it’s covered by two patents. There is no reflective
surface as found in other detectors so it is virtually immune to false
alarms generated by dust or dirt build-up. With this unique chamber
design it can detect slow, smoldering fires and flash fires equally
well. With 2-wire, 4-wire, addressable and wireless versions, plus
options for relay type, built-in sounder and fixed-temperature sensor,
Meridian is ready for your next security or fire alarm installation.
Several variations are available, including models
with a built-in 85dB sounder, a built-in heat detector (rated at 57oC
or 135oC), interconnect relay and Form ‘C’ auxiliary relay options.
All models are non-latching and include Form ‘A’ alarm
relay contacts.

DSC is committed to reducing
false alarms and has integrated features like drift
compensation. This feature provides a constant level of sensitivity
performance for extended operation by automatically compensating to
maintain the detector’s original factory-set sensitivity as dust
accumulates.

Photoelectric Smoke Detector Interconnect
with Relay and horn
The System Sensor 2012HA photoelectronic detector is
designed primarily for applications where low-voltage Class 2 wiring
may be used. This detector
is non-latching and offers an 85dB alarm horn. The 2012HA features an
audible emergency evacuation signal referred to as temporal (3) tone.
An external push button provides a test of the detector’s alarm
function. Up to 12 units can be interconnected so that if one detector
alarms, all detectors alarm. A normally open auxiliary alarm relay
with an 8 second delay is available for controlling external
functions. A visible LED indicator flashes once every 30 seconds in
standby and rapidly (every 0.5 seconds) in alarm when detecting smoke.
The detector offers low-voltage operation and a tamper-proof feature.
Screw terminals and a mounting bracket are provided for easy
installation.

N.O. contact
(.5A@30VDC) Built-in, normally open
relay can be connected to lights, bells, horns, or remote annunciator
Designed to activate an auxiliary ( like an
alarm control panel ) device when an alarm is initiated. The relay
contacts will activate whenever any interconnected alarm sounds. The relay
contacts will automatically deactivate a few seconds after the alarm stops
sounding. The RM4 may be wired next to an AC alarm or from a remote
location. This relay must be installed in a junction box.
The RM4 has form-C contacts that, once connected to BRK 120volt AC
alarms, automatically activate whenever the alarm sounds and will
automatically deactivate when the alarm shuts off. Meets UL 317,
UL2034 and UL539 for accessories.
Please note
RM3 relay by BRK had the same functions.
The voltage used by BRK smoke detectors to interconnect the 110VAC
devices was changed from 120VAC to 9VDC few years ago. That change, on
the way detectors works, is reflected on the operation of the relay.Do
not mix relays and detectors as they are not compatible unless same
interconnect voltage is used
The BRK 7010A is a wire-in, 120 VAC 60Hz single and/or
multiple station smoke alarms specifically designed for
residential and institutional applications including sleeping rooms of
hospitals, hotels, motels, dormitories and other multi-family
dwellings as defined in standard NFPA 101. Both models comply with
UL217, CSFM, NFPA 72, HUD, FHA and other agencies that model their
codes after the above agencies. It meets building codes where AC or
AC/DC smoke alarms are required. Model BRK 7010BA includes a 9V
battery backup.
