7.13.3 Installation Considerations
Proper location of detection devices is one of the most critical factors
in a fire alarm system.
The following are some general considerations:

• Smoke detectors should not be installed in “dead air” spaces or
close to ventilating or air conditioning outlets because smoke may
be circulated away from the detector. Locations near air inlets
should be favored.
• Avoid areas subject to normal smoke concentrations such as
kitchens, garages, or near fireplaces.
• Do not install smoke detectors where normal area temperatures
are above 100 degrees F (38 degrees C) or below 32 degrees F
(0 degrees C).
• Areas of high humidity and dust concentrations should be avoided.
• The edge of ceiling mounted detectors should be no closer than
4 inches (10 cm) from any wall.
• Place the top edge of wall mounted detectors between 4 and 12
inches (10 to 30 cm) from the ceiling.
7.14 Testing
7.14.1 System Walk Test
The System Walk Test is used to confirm that detectors will report alarms. System Walk Test works on all zones, except 24-hour zones and
fire zones. At the start of the System Walk Test a System Walk Test report, if programmed, is sent to the central station, followed by reports
from the individual zones as they are tested. A System Test restoral is sent upon completion of the System Walk Test. If System Walk Test
Report, Address 0339, and System Walk Test Restoral, Address 0340, are not programmed, no zone reports are sent during the System
Walk Test.
DS7447:
“Test Zone”
will display followed by the
zone number of any zones that have not been tested.
DS7445: The Zone LEDs will flash for any zones that
have not been tested.**
DS7447:
“Now Testing”
will be displayed followed
by the zone number of the zone that is currently being
violated (being tested). It returns to
“Test Zone”
after
the violation.
DS7445: The Zone LED will turn on steady for the
zone that is currently being violated (tested).
Test each detector one at a
time as instructed by the
installing company.

7.13.2 Having and Practicing an Escape Plan
A fire warning may be wasted unless the family has planned in
advance for a rapid and safe exit from the building.
• Draw a floor plan of the entire house showing two exits from each
bedroom and two from the house. Since stairwells and hallways
may be blocked during a fire, the plan should provide exits from
bedroom windows.
Make copies of the plan and practice it with all family members.
• Pre-arrange a meeting place outside and away from the residence.
Once out of the building, all occupants should immediately go to
the pre-selected location to be accounted for.
• Provide a barricade between family members and fire, smoke,
and toxic gases (e.g. close all bedroom doors before retiring).
• Children should be instructed on opening their bedroom windows
and exiting safely from the building. If exiting is not possible, they
should be taught to stay at the open window and shout for help
until it arrives.
• In the event of a fire alarm after retiring, wake the children by
shouting to them from behind your closed door. Tell them to keep
their bedroom doors closed.
• If the top of your bedroom door is uncomfortably hot, do not open
it. There is most likely fire, intolerable heat, or smoke on the other
side. Shout to all family members to keep their bedroom doors
closed and to exit the building via alternate routes.
• If the top of the door is not uncomfortably hot, brace the bottom of
the door with your foot, and the top with one hand, then open the
door about one inch. Be prepared to slam the door shut if there is
any pressure against the door or if any hot air rushes in.
• If there is no evidence of excessive heat or pressure, leave the
room and close the door behind you. Shout appropriate
instructions to all family members and immediately leave the
building via the pre-planned routes. If heavy smoke is present,
drop to your hands and knees, or crawl to remain below the smoke
level.
