Introduction
The DSC Meridian photoelectric smoke detector incorporates
many advanced design features to provide years of reliable
operation. It is important to follow the installation and operation
instructions on this sheet to ensure that the unit will function
properly — even the best designed smoke detector will be rendered
useless if it is not connected or located properly.
It is very important that you understand how to test and maintain
your system. Read the
system to familiarize yourself with the fire alarm functions. Be sure
to test your system regularly following the test procedures described
in your manual. If you should ever have problems operating or
testing your system, and especially if there are problems with the
fire alarm functions, contact your smoke detector installer or dealer
immediately for service.
While smoke detectors and alarm systems are designed to warn you of
potentially dangerous situations, no system can prevent emergencies.
An alarm system is not a substitute for life and property insurance; you
should always maintain appropriate insurance coverage.

How the Smoke Detector Works
As shown in the illustration, a light source is directed across the
smoke chamber and is not normally reflected into the sensing
element. When smoke enters the chamber, the light beam is
scattered by the smoke and is reflected into the sensor. When
enough light is detected by the sensor, an alarm is activated. On
alarm, the sounder is activated and the red LED will flash.
When
the smoke clears from the smoke chamber, the unit will
automatically reset itself.

Limitations of Smoke Detectors
While the Meridian smoke detector has been designed for reliability,
it is important to know that all smoke detectors have limitations.
• Smoke detectors will not work without power. If the batteries are
low, the smoke detector will not function. See ‘Battery Installation’
below for important information on battery use.
• Smoke detectors can only generate an alarm when smoke gets
inside the smoke chamber; anything that prevents smoke from
entering the smoke chamber may prevent or delay an alarm.
Refer to the ‘Guidelines for Locating Smoke Detectors’ on this
Instruction Sheet
on at least every floor of the premises, preferably in every room.
It is also important to avoid obstructions, such as closed doors,
that may prevent smoke from reaching the unit. A smoke detector
will not detect a fire in the walls, in the chimney or on the roof of
a building until smoke enters the smoke chamber.
; it is important that smoke detectors be located
• Smoke detectors have certain obvious limitations: they may not
provide protection for someone smoking in bed, for children
playing with matches, or for sudden and violent explosions. A
smoke detector is a single part of overall fire safety precautions;
the smoke detector should never be seen as a substitute for a
complete fire safety program.
Guidelines for Locating Smoke Detectors
On smooth ceilings, detectors may be spaced 9.1m (30 feet) apart
as a guide. Other spacing may be required depending on ceiling
height, air movement, the presence of joists, uninsulated ceilings,
etc. Consult National Fire Alarm Code NFPA 72, CAN/ULS-S553M86 or other appropriate national standards for installation
recommendations.
Do not locate smoke detectors at the top of peaked or gabled
ceilings; the dead air space in these locations may prevent the unit
from detecting smoke.
Avoid areas with turbulent air flow, such as near doors, fans or
windows. Rapid air movement around the detector may prevent
smoke from entering the unit.
Do not locate detectors in areas of high humidity.
Do not locate detectors in areas where the temperature rises
above 38
o
C (100oF) or falls below 5oC (41oF).
Testing Your Smoke Detector
Follow the test procedure described here or contact your
smoke detector dealer or installer for testing instructions.
It is recommended that your entire alarm system be tested at
least once per week to verify the operation of all system
functions.
Smoke Detector Unit Test
To test the smoke detector, press and hold the test button on the
front of the unit. When the button is pressed, the unit’s alarm should
sound. When the button is released, the alarm should be silenced.
If this does not occur, check that the batteries are the correct type,
‘
in good condition and are installed correctly (see the
Installation’ section below).
Upon completing the functional testing of the smoke detector,
check the unit’s sensing chamber to ensure proper operation. To
test the sensing chamber, waft a lit cotton wick or punk stick
around the outside of the unit until a generous amount of smoke
enters the sensing chamber, or the unit alarms. If the smoke
detector does not function properly, call your smoke detector
installer or dealer for service.
System Test
To prepare your alarm system for a complete test, refer to the testing
instructions section of your system’s manual.
instructions regarding notification of the monitoring station in
order to avoid an unnecessary emergency response.
system is ready to be tested, hold the test magnet against the smoke
detector case as shown below.
After activating the smoke detector’s system test, an alarm should
sound and the indicator light should flash every 0.67 seconds.
When the magnet is removed, the alarm should be silenced.

Smoke detectors should always be installed in accordance with
NFPA 72, the National Fire Alarm Code. Smoke detectors should
always be located in accordance with:
• Paragraph 2-2.1.1.1 of NFPA 72, Chapter 2.:
“Smoke detectors
shall be installed outside of each separate sleeping area in the
immediate vicinity of the bedrooms and on each additional story
of the family living unit, including basements and excluding crawl
spaces and unfinished attics. In new construction, a smoke
detector also shall be installed in each sleeping room.”
• Paragraph 2-2.1.1.2 of NFPA 72, Chapter 2.:
“Split level
arrangement. Smoke detectors are required where shown. Smoke
detectors are optional where a door is not provided between
living room and recreation room.”
Owner’s Maintenance Instructions
The Meridian smoke detector is designed to require a minimum of
maintenance. If the case becomes dusty, wipe the case gently with
a soft dry cloth. If the case is greasy, wipe the case gently with a soft
cloth slightly dampened with soapy water.
Never disassemble the smoke detector; there are no user
serviceable parts inside the unit. Never paint the unit, as paint
may prevent smoke from entering the unit. If you are planning
renovations or repainting, contact your installer and ask that
the unit be temporarily removed until work is complete.
If the unit is located in an area where it is exposed to high levels of
dust or insects and is found to cause false alarms, it may require
service; contact your smoke detector installer or dealer.
