DSC Meridian Instruções de instalação e operação

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.

Household Fire Safety Audit

1 Are all electrical appliances and outlets in a safe condition? Check

for frayed cords, overloaded lighting circuits, etc. If you are

uncertain about the condition of your electrical appliances or

household service, have a professional evaluation.

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.

1 Every family member should participate in developing the escape

plan.

2 Study the possible escape routes from each location within the

house. Since many fires occur at night, special attention should be

given to the escape routes from sleeping quarters.

3 It is essential that escape from a bedroom be possible without

opening the interior door. Consider the following when making

your escape plans:

• Make sure that doors and windows that open to the outside are

easily opened. Ensure that they are not painted shut, and that their

locking mechanisms operate smoothly.

• If opening the exit or using the exit is too difficult for children, the

elderly or handicapped, plans for rescue should be developed.

This includes making sure that those who are to perform the rescue

can promptly hear the fire warning signal.

• If the exit is above the ground level, an approved fire ladder or rope

should be provided, as well as training in its use.

• Exits on the ground level should be kept clear. Be sure to remove

snow from exterior patio doors in winter; outdoor furniture or

equipment should not block exits.

• The family should have a predetermined assembly point where

everyone can be accounted for; for example, across the street or

at a neighbour's house.

• Once everyone is out of the house, call the Fire Department.

• A good plan emphasizes quick escape. Do not investigate first or

attempt to fight the fire, and do not attempt to rescue belongings or

valuables as this takes up time. Once outside, do not re-enter the

house; wait for the Fire Department.

• Write the plan down and rehearse frequently so that should an

emergency arise, everyone will know what to do. Revise the plan as

conditions change; for example, when there are more or fewer

family members in the home, or if there are changes to the house.

• Make sure your fire warning system is operational by conducting

weekly tests. If you are unsure about system operation, contact

your Smoke Detector Installer or Dealer.

• It is recommended that you contact your local fire department and

request further information on home fire safety and escape planning.

If available, have your local fire prevention officer conduct an in-

house fire safety inspection.

Dimensions

Mounting the Unit

The Meridian Smoke Detector mounts to a standard 4" octagonal

electrical box. 12 to 24V

or Full Wave Rectified power must

be supplied from a ULC-listed power supply or the auxiliary

power terminals of a ULC-listed alarm control unit. Wiring

should be in accordance with the Canadian Electrical Code,

Part I, and applicable local codes.

Remove the mounting plate from the case by pushing the locking

tab and turning the mounting plate counter-clockwise. Attach the

mounting plate to the electrical box (see diagram below for

orientation).

4-Wire Detector System Wiring

Installation Testing

When all connections are completed, apply power to the system as

described in the control panel's Installation Manual. If all connections

are correct, there should be no alarm from any of the smoke

detectors. If an alarm occurs, ensure that there is not an actual alarm

condition. If there is no actual alarm, remove power from the system

and check all smoke detectors for correct wiring.

If no alarm occurs, test each smoke detector by holding the test

magnet against the case near the Alarm Indicator. Refer to the

illustration in the "Testing Your Smoke Detector" section of these

instructions. When the magnet is in place, an alarm will be activated:

the Alarm Indicator Light will come ON, the Alarm Relay will be

activated, the Sounder (if equipped) will sound, and the alarm control

panel will indicate a fire alarm. When the magnet is removed, the

Sounder will be silenced and the detector will remain latched in the

alarm condition. To reset the detector, remove the power supplied by

the alarm control panel.

Installer's Maintenance Instructions

Normally, the Meridian Smoke Detector will not require maintenance.

If the unit is mounted in a high dust environment, the inlet areas of the

case may be vacuumed with a soft brush attachment.

Be sure to inform the user and their monitoring station when

maintenance of any sort is performed on the smoke detector or any

part of the alarm control system. Always test smoke detectors after

maintenance. If a smoke detector continues to generate nuisance

alarms even after vacuuming, return the unit to DSC for service.

Contact DSC at the address and number below to obtain a return

authorisation number before returning the unit.

Installer's Responsibility to the User

It is the Installer's responsibility to thoroughly instruct the end user of

the system on the operation, testing and maintenance of their system.

The Installer should fully explain and demonstrate all functions of the

alarm control system and any equipment, such as smoke detectors,

connected to it. The user should be provided with all Instruction

Sheets and Manuals for their system and any components connected

to it. Complete and thorough instruction for the user is essential to

ensure they will obtain the greatest benefit from their system. Providing

the user with complete operational information will also benefit the

Installer through a reduction in service calls for nuisance alarms.

of abuse, alteration or improper application of the equipment.

The foregoing warranty shall apply only to the original buyer, and is and shall be in

lieu of any and all other warranties, whether expressed or implied and of all other

obligations or liabilities on the part of Digital Security Controls Ltd. Digital Security

Controls Ltd. neither assumes, nor authorizes any other person purporting to act on

its behalf to modify or to change this warranty, nor to assume for it any other warranty

or liability concerning this product.

In no event shall Digital Security Controls Ltd. be liable for any direct, indirect or

consequential damages, loss of anticipated profits, loss of time or any other losses

incurred by the buyer in connection with the purchase, installation or operation or

failure of this product.

Smoke detectors that are a part of this system may not properly alert occupants of a

fire for a number of reasons, some of which follow. The smoke detectors may have

been improperly installed or positioned. Smoke may not be able to reach the smoke

detectors, such as when the fire is in a chimney, walls or roofs, or on the other side of

closed doors. Smoke detectors may not detect smoke from fires on another level of

the residence or building.

Every fire is different in the amount of smoke produced and the rate of burning. Smoke

detectors cannot sense all types of fires equally well. Smoke detectors may not

provide timely warning of fires caused by carelessness or safety hazards such as

smoking in bed, violent explosions, escaping gas, improper storage of flammable

materials, overloaded electrical circuits, children playing with matches or arson.

Even if the smoke detector operates as intended, there may be circumstances when there

is insufficient warning to allow all occupants to escape in time to avoid injury or death.

Warning: Digital Security Controls Ltd. recommends that the entire system be

completely tested on a regular basis. However, despite frequent testing, and due to, but

not limited to, criminal tampering or electrical disruption, it is possible for this product

to fail to perform as expected.

Important Information: Changes or modifications not expressly approved by Digital

Security Controls Ltd. could void the user's authority to operate this equipment.
