INTRODUCTION

The 713LS Smoke Alarm is a Photoelectric Type Alarm for use as an evacuation device in residential applications, while the 710LS is for use as an alert and relocate device. Each alarm has a solid state piezo signal to warn and alert the household to the presence of

threatening smoke.

Your Photoelectric alarm is designed to detect the smoke that results from an actual fire. Consequently, it is uncommon for household smoke such as cigarette smoke or normal cooking smoke to cause an alarm.

Under normal conditions, the light generated by the pulsing infrared LED is not seen by the light sensor, as it

is positioned out of the direct path of the light beam. When smoke enters the sensing chamber, light from the pulsing LED light source is reflected by the smoke particles onto the photodiode light sensor. At the first sighting of smoke, the alarm is put into a pre-alarm mode. This is indicated by a rapidly flashing LED on the face of the alarm. Once the light sensor confirms smoke for 2 consecutive pulses inside the chamber, the light sensor produces the signal necessary to trigger the alarm.

This technique of verifying the smoke condition, combined with a 5-to-1 signal-to-noise ratio, substantially reduces the possibility of nuisance alarms.

MODEL NO.		DESCRIPTION
710LS*	120 VAC Wall Mounted, Provided
	With a 9 ft. Line Cord, Pulsating Horn
713LS	Same as 710LS but with a Temporal Horn

*This unit produces a non-temporal audible alarm and is therfore not intended for locations where the desired action of the occupant(s) is evacuation.

NOTE: Loss of electrical input will cause the alarm not to function. For maximum safety you should install both battery operated and AC powered smoke alarms.

HOW YOUR SMOKE

ALARM WORKS

The 710LS/713LS Smoke Alarm operates on the photoelectric light scatter principle. The unit's sensing chamber houses a light source and a light sensor.

The darkened sensing chamber is exposed to the atmosphere and designed to permit optimum smoke entry from any direction while rejecting light from outside the alarm.

The light source is an infrared (invisible) LED which pulses every 8 seconds. The light sensor is a photodiode matched to the light frequency of the LED light source.

HOW TO TELL IF YOUR SMOKE ALARM IS WORKING PROPERLY

·Your alarm is provided with an alarm horn and pulsating Light Emitting (indicator) Diode, which pulses every 15-30 seconds, and a green AC power on LED.

·When turning the test knob on the alarm to TEST 1, the red LED will rapidly flash, the horn will sound and the strobe light will flash. If AC power fails, the green LED will turn off.

·The test knob of your alarm simulates actual smoke conditions.

FIRE PROTECTION PLAN

This Smoke Alarm can quickly alert you to the presence of smoke-it cannot prevent fire. Please note that there are hazards against which smoke detection may not be effective, such as smoking in bed, explosions, when a closed door separates the alarm from the source of the smoke, etc. The ultimate responsibility for fire protection rests solely on you.

1.To minimize fire hazards-avoid improper storage of flammable liquids and don't leave small children home alone.

2.Bedroom doors should be closed while sleeping if a smoke alarm is installed in the bedroom. They act as a barrier against heat and smoke.

3.Establish an escape plan:

(a)Post a detailed floor plan depicting the chosen escape routes.

(b)Each bedroom should have at least two escape routes.

(c)Make sure your children know what to do in case of fire and teach them to follow the escape plan you have posted.

(d)Agree on an outside meeting place.

(e)Conduct fire drills at least twice a year.

(f)Be sure each member of the family is familiar

with the smoke alarm so they can react properly. If the smoke alarm should sound:

1.Never waste time dressing or gathering valuables. Follow the escape route and leave the house immediately.
