Guidelines for Locating Smoke Detectors

On smooth ceilings, detectors may be spaced 9.1m (30 feet) apart

as a guide. Other spacings may be required depending on ceiling

height, air movement, the presence of joists, uninsulated ceilings,

etc. Consult National Fire Alarm Code NFPA 72, CAN/ULC-S553-

M86 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

C (100

F) or falls below 5

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 2.1.1.1 of NFPA 72, Chapter 2.:

"2-2.1.1.1 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."

Testing Your Smoke Detector

Test the detector for minimum sensitivity by activating the test feature.

To test the unit, hold the test magnet against the case as shown. The

Alarm Indicator Light will come ON, the Auxiliary Relay (if equipped) will

be activated, and the alarm control panel should indicate a fire alarm.

When the magnet is removed, the Alarm Light and Auxiliary Relay will

remain ON. Turn off the voltage supply from the control panel to the

C (41

F).

Smoke Sensitivity

may be measured in

a correlated UL268

or CAN/ULC S529-

M87 smoke box. DSC will conduct this test for a nominal charge. If a

returned unit is found outside of its marked sensitivity range, DSC will

clean and restore the unit's sensitivity to its marked range.

Smoke sensitivity of installed detectors can be measured without

removal with the Gemini Model 501 Aerosol Smoke Detector Analyzer.

Follow the instructions supplied with the instrument. Start with the

sensitivity corresponding to the lowest marked detector sensitivity; no

alarm should be indicated. Reset with the highest sensitivity setting;

an alarm should then be indicated. These results indicate that the unit

is within its marked sensitivity range. Other settings can be tried to

bracket the detector's sensitivity to a narrower sensitivity range, such

as may be important during annual tests to quantify any change over

time.

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.

Fire Safety In The Home

Most fires occur in the home, and to minimize this danger, it is

recommended that a household fire safety audit be conducted and

a family escape plan be developed.

2 Are all flammable liquids stored safely in closed containers in a

cool, well ventilated area? Cleaning with flammable liquids should

be avoided.

3 Are hazardous materials such as matches out of the reach of

children?

4 Are furnaces and wood burning appliances properly installed,

clean and in good working order? If in doubt, have a professional

evaluation.

Family Escape Planning

There is often very little time between the detection of a fire and the

time it becomes deadly. Because of this, it is very important that a

family escape plan be developed and rehearsed.
