• Do not install a smoke alarm in dusty or dirty areas; SUCH AN
INSTALLATION CANNOT BE RELIED UPON. An accumulation of dust
and dirt in the sensing chamber may block the openings and prevent an
alarm, or may get inside the alarm and cause false alarms. If a smoke
alarm is required in such an area, vacuum it frequently and test it
according to the section TAKING CARE OF YOUR SMOKE ALARM.
• Do not install a smoke alarm in the dead air space in the corner where
the wall meets the ceiling. If in doubt as to the exact location of
mounting, for your safety, contact your local fire department for help in
choosing a location.
• Do not install a smoke alarm where bugs or insects are present before
eliminating or minimizing the bug problem. Although all smoke alarms
built since 1986 are made to help prevent bugs from entering the detec-
tion chamber, bugs may build up on chamber openings and prevent
smoke from entering. As a result, unit should be vacuumed frequently
as explained in the section TAKING CARE OF YOUR SMOKE ALARM.
• Do not install a smoke alarm within close proximity of a fluorescent
light. Electrical noise may cause nuisance alarms.
HOW TO INSTALL YOUR SMOKE ALARM
AFTER CAREFULLY HAVING READ THE
FIRST FIVE SECTIONS OF THIS MANUAL,
YOU ARE READY TO INSTALL YOUR
SMOKE ALARM.
PLEASE FOLLOW THESE DIRECTIONS:
1. Unlock and remove mounting bracket
from smoke alarm with a
counterclockwise twist.
2. Place mounting bracket on ceiling or
wall in prearranged location and use
pencil to trace two opposing hole
positions for mounting screws. Drill
two 1/16inch holes.
3. Use mounting screws provided for attaching to studs or woodwork.
For plaster or plasterboard, you may wish to use plastic anchors and
screws. See Figure 6.
4. Screw mounting bracket to surface securely. NOTE: Before mounting
alarm on a wall, be sure arrow on mounting bracket is pointing up
toward ceiling. See Figure 6.
5. Install battery. (See REPLACING THE BATTERY.)
6. Attach smoke alarm to mounting bracket with a clockwise twist until it
snaps into locked position. NOTE: Your smoke alarm is designed with
a safety mechanism that prevents mounting unless a battery is
installed. This helps ensure the alarm is functional when mounted.
7. You now have finished installing your smoke alarm. For your safety,
proceed with testing described in the next section.
WEEKLY TESTING OF YOUR SMOKE ALARM
1. FOR A COMPLETE WEEKLY TEST OF THE ELECTRONICS AND THE
SENSOR OPERATION, FIRMLY DEPRESS THE TEST BUTTON ON
THE COVER OF THE SMOKE ALARM FOR A FEW SECONDS. The
smoke alarm will sound 3 short beeps followed by a 2-second pause
and then repeats. On models with an LED (light emitting diode) the
indicator light under the clear Push-to-Test button will blink once per
