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

A smoke detector should be located on each

• 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 kitch-
ens, 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 avoid-
ed.
• 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.
8.13 Testing
8.13.1 Zone Test
The Zone Test is used to confirm that detectors will report alarms. Zone Test works on all zones, except 24-hour zones and fire zones.
While the keypad is in Zone Test, no reports will be sent and no control panel alarms will activate an alarm, except 24-hour zone alarms and
fire alarms. These will override the Zone Test function.
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.
To exit the Zone Test mode,
enter your PIN + the [#] key.

8.13.2 Battery/Sounder Test
If a power failure occurs, your control panel has a built-in battery that will continue to power the control panel for several hours. The control
panel automatically recharges the battery when power is restored. In addition to an automatic battery test performed every 4 hours, the
battery may also be tested manually. This test also uses the battery to manually activate all the system sounders for 2 seconds (# 8 5 only).
If the battery voltage is low, a battery fault will occur (see Error Display).

• The keypad sounder and all alarm
sounding devices will operate for 2

If test fails, the control will indicate
a Control Problem. See Error
displays, section 9.20.
If power in your building has been
off recently, wait 2 hours for the
battery to recharge and then try
again.
Battery Test
• The control will perform a Battery Test.
• The control will report a Low Battery or
a Low Battery Restoral if necessary.

it must be in Single Partition Mode.
