Smoke Alarm with Heat Detection Sensor

Product Introduction

This wireless photoelectric smoke alarm and heat detector (product)
continually monitors operational status and provides a visual trouble
condition if it drifts out of the sensitivity range or fail internal diagnostics.
This product meets National Fire Protection Association (NFPA) 72 field
sensitivity testing requirements without the need for external meters.
The alarm sensitivity level can be determined at the product. Another
feature is built-in drift compensation that allows the product to adjust
sensitivity automatically as it becomes dirty over time. The drift
compensation feature dramatically increases the time between
cleanings, and reduces the chance of a nuisance alarm. Additional
diagnostic information is activated by applying a magnet near the
detector’s integral reed switch. This initiates a self-diagnostic routine
and provides visual indication of sensitivity level, or if service is
required. The product is powered by long-life 3V Lithium batteries
providing power to both the sensor and wireless transmitter.

This wireless product works in conjunction with your wireless Control
Panel, providing a local indication.

Pre-installation Considerations

Install the smoke alarm in accordance with NFPA Standard 72,
Chapters 17 and 29. Depending on the application, you may need to
reference other chapters of NFPA 72 or NFPA 101.

Choosing an Installation Location

When choosing an installation location, consider:

o Use of structure and type of construction
o Contents you want to protect and their burning characteristics
o Human occupancy
o Total area to be monitored
o Ceiling height and surface condition
o Air movement and vent locations
o Obstructions
o Deflections

All Rights Reserved. 1 P/N 3102233 – Rev. A – Oct 16, 2014

After considering these factors, choose a location:

o Where the temperature and humidity are within the product

temperature range.

o Away from ventilation sources that can prevent smoke from

reaching the smoke alarm.

o ‘Smoke alarms and smoke detectors shall not be installed

within a 36 in. (910 mm) horizontal path from a door to a
bathroom containing a shower or tub unless listed for
installation in close proximity to such locations.’

The product shall be located on the ceiling or, if on a sidewall, between
the ceiling and 12 in. (300 mm) down from the ceiling to the top of the
detector.

In rooms with sloped, or peaked ceilings, place smoke alarms 3 feet
(910 mm) down or away from the highest point of the ceiling.

If mounting to suspended ceiling tile, secure the tile with the
appropriate fastener to prevent tile removal.

Smoke Alarms are not to be used with alarm guards unless the
combination has been evaluated and found suitable for that purpose.

Note: A smoke alarm does not provide warnings for fires resulting from
explosions, smoking in bed, or other furniture; ignition of flammable
liquids, vapors, and gasses; and children playing with matches or
lighters.

Locations to Avoid

o Areas where normal ambient temperature exceeds products

operating temperature range.

o Dirty, dusty, insect infested areas.
o In or near areas with combustion particles (kitchens, garages,

furnaces, hot-water heaters, gas space heaters).

o On the ceiling in rooms next to kitchens, where there is no

transom between the kitchen and such rooms.

o Damp or humid areas, or near bathrooms with showers.
o Near fresh-air inlets or returns or very drafty areas.
o Near heating/air conditioning vents, fans, and fresh air intakes,

which can drive smoke away from the smoke alarm.

o In dead-air spaces at the top of peaked ceilings or in corners

where walls and ceiling meet. Dead air can prevent smoke
from reaching a smoke alarm/alarm.

o Within 10 feet (3 m) of fluorescent light fixtures.
o Not suitable for outdoor use.

alarm. If a fire starts in a chimney, wall, roof, on the other side of closed
doors, or on a different level of the property, enough smoke may not
reach the alarm for it to alarm.

Smoke Alarms are a significant help in reducing loss, injury and even
death. However, no matter how good a detection device is, nothing
works perfectly under every circumstance and we must warn you that
you cannot expect a smoke alarm to ensure that you will never suffer
any damage or injury.

Current studies have shown smoke alarms may not awaken all
sleeping individuals. It is the responsibility of individuals in the
household that are capable of assisting others to provide assistance to
those who may not be awakened by the alarm sound, or to those who
may be incapable of safely evacuating the area unassisted.

WARNING The product should be installed in a location that

must maintain a minimum distance of 7.87 inches (20 cm) between the
product and a person.

3. Mounting the Sensor

Note: Add the product to the Control Panel before physically mounting
the smoke alarm in the desired location.

A. Disconnect alarm-notification appliances, service-release devices,

and extinguishing systems. Test communications between the
control panel and smoke alarm before permanently mounting the
smoke alarm as follows:

− Hold the smoke alarm where you plan to install it.

− Press the smoke alarm test button for 8-to-10 seconds. The

smoke alarm sends a signal to the control panel.

− At the control panel, verify the signal was received and RF

signal strength is adequate. If no signal is received or the RF

signal is low, relocate the smoke alarm and retest.

B. Using two supplied screws and anchors, mount the base with this

arrow pointing towards the wireless Control Panel.

WARNING! LIMITATIONS OF SMOKE ALARMS

Wireless smoke alarms are very reliable, but may not work under all
conditions. No fire alarm provides total protection of life or property.

Smoke Alarms require a source of power to work.

This smoke alarm will not operate and the alarm will not sound if
batteries are dead or not installed properly.

Smoke Alarms may not be heard. A sound sleeper or someone who
has taken drugs or alcohol may not awaken if the alarm is installed
outside a bedroom. Closed or partially closed doors and distance can
block sound. This alarm is not designed for the hearing impaired.

Smoke Alarms may not always activate and provide warning early
enough. Smoke alarms only activate when enough smoke reaches the

− Line up the raised alignment tab on the lip of the smoke

alarm with the arrow on the mounting base.

− Insert the smoke alarm into the base and turn clockwise

about 15 degrees until it snaps into place.

Note: The product cannot be attached to the mounting base if no
batteries are installed.
