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 Instruction or User Manual for your alarm

system to familiarise 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.

System Test To prepare your alarm system for a complete test, refer to the testing instructions section of your system’s manual. Observe carefully all instructions regarding notification of the monitoring station in order to avoid an unnecessary emergency response. When the system is ready to be tested, hold the test magnet against the smoke alarm case as shown below. After activating the smoke alarm’s system test, an alarm should sound and the indicator light should flash every 0.67 seconds.

place. Install the last two batteries, with their + terminals facing to the left, by snapping them past the nylon retainer. Use six AA Alkaline Energizer E91, or Duracell MN1500 batteries. Do not use other brands of batteries for the smoke detector. Using brands other than the Energizer E91 or Duracell MN1500 may affect the operation of the system. Batteries may be purchased in supermarkets and hardware stores.
