Smoke Detector Installation
Instructions
Features
PGx926 smoke detectors provide open area protection and
early warning of developing fires by:
• Activating a fire alarm upon a smoke condition.
• Sounding an alarm with its built-in alarm horn.
• Transmitting a coded alarm signal to a compatible wireless
alarm control panel.
Operation
The Test / Mute switch functions during normal operation as a
Test switch and during an alarm condition as a Mute switch.
Pressing the Test / Mute switch during an alarm condition stops
the buzzer sound for 8 minutes. If the condition is not restored
after 8 minutes, the buzzer will resound. Pressing the mute
switch will not restore the alarm condition.
The tamper switch actuator is depressed when the unit is
attached to the mounting bracket. Removal of the unit from the
mounting bracket causes the switch contacts to open,
transmitting a tamper event to the alarm system control panel.
The detector is disabled when not attached to the mounting
bracket.
Device Setup
Attention:
The detector battery cover is fitted with a red button
that prevents the detector from locking onto the mounting
bracket if there is no battery inside. The smoke detector is
supplied with a 3V CR123A battery.
Caution!
To be installed by service persons in non-hazardous
locations only. Risk of explosion if battery is replaced by an
incorrect type. Dispose of used batteries according to the
manufacturer's instructions and according to local rules and
regulations. Batteries are to be replaced by service persons
only.
WARNING:
Never remove batteries to stop a false alarm.
Open a window or fan the air around the detector to get rid of
the smoke. The alarm will turn itself off when the smoke is
gone. If false alarms persist, attempt to clean the detector as
described in this manual.
WARNING:
Do not stand close to the detector when the alarm
is sounding. The alarm is loud in order to wake you in an
emergency. Too much exposure to the horn at close range may
be harmful to your hearing.
Note:
To keep the smoke detector in good working order, you
must test it weekly.
Note:
To ensure the continued operation of all wireless devices
after performing a system default, a global upload of all
wireless programming via DLS is recommended before
defaulting the system. After completing the system default,
download the wireless programming.

Where to Install Smoke Detectors
Smoke detectors should always be installed in USA in
accordance with Chapter 29 of NFPA 72, the National Fire
Alarm Code: 29.5.1.1. Where required by other governing
laws, codes, or standards for a specific type of occupancy,
approved single- and multiple-station smoke alarms shall be
installed as follows:
1. In all sleeping rooms and guest rooms.
2. Outside of each separate dwelling unit sleeping area, within
21 ft (6.4 m) of any door to a sleeping room, with the dis-
tance measured along a path of travel.
3. On every level of a dwelling unit, including basements.
4. On every level of a residential board and care occupancy
(small facility), including basements and excluding crawl
spaces and unfinished attics.
5. In the living area(s) of a guest suite.
6. In the living area(s) of a residential board and care occu-
pancy (small facility).
7. When mounting on ceiling the closest edge of the detector
must be at least 4” (.1m) from the wall.
8. When mounting on wall the closest edge of the detector must
be at least 4” (.1m) and no more than 12” (.3m) from the ceil-
ing.
9. When mounting on sloped, gabled or peaked ceilings the
horizontal distance of the furthest edge of the detector from
the peak must be no more than 3 ft (.9m).
CAUTION!
(As required by the California State Fire Marshall)
Early warning fire detection is best achieved by the installation
of fire detection equipment in all rooms and areas of the
household as follows:
(1) A smoke detector installed in each separate sleeping area (in
the vicinity, but outside the bedrooms), and (2) Heat or smoke
detectors in the living rooms, dining rooms, bedrooms,
kitchens, hallways, attics, furnace rooms, closets, utility and
storage rooms, basements and attached garages.
Mounting
Before permanently
mounting any wireless device
it is recommended to mount
the device temporarily and
perform a placement test.
1. Mark and drill 2 holes in
the mounting surface. Fas-
ten the bracket to the
mounting surface with 2
screws.
2. Align bracket tabs with the detector slots and rotate the
detector as shown. Pull the detector outward to verify that it
is securely attached.
Notes:
A battery must be inserted into the detector before the
detector can be mounted onto the bracket. Unauthorized
removal of the unit from the bracket will initiate a tamper alert!
Configuration
To enter the wireless configuration section enter [804][Zone
Number].
Device Toggles
Audible and Visual Indications
The dual color LED, buzzer and siren are used to signal various
alarm and trouble messages as shown below:
Clearing Alarm Memory
Alarm memory will be cleared each time the system is armed.
*The tamper alarm will mute for 3 minutes at first power on,
and will revert to normal mode when the tamper switch
condition is changed.
**Delay of 15 sec. between buzzer beep and LED operation.
Battery Replacement
CAUTION:
This product uses lithium batteries, improper
handling may result in a HEAT, EXPLOSION or FIRE causing
personal injury. DO NOT recharge batteries. Follow the battery
manufacturer’s safety instructions. Dispose of used batteries in
accordance with the regulations in your area.
Replace the detector’s battery (lithium) once every 8 years even
if there is no indication that the battery is weak. Also be sure to
replace it immediately upon reception of a low battery message
via your control panel.
If you disregard this message, an audible reminder in the form
of once-per-minute "beep" will sound after a few days. The
low-battery “beep” should last at least 30 days before the
battery dies out completely.
Maintenance
It is necessary to maintain the detector frequently to ensure
proper operation. Follow these tips for taking care of your
detector:
• Use a vacuum cleaner occasionally to keep the air vents free
from dust. When a "Clean Warning" transmission is
received, the detector should be cleaned. When a trouble
event is received, the detector should be removed.
• Perform detector functional test weekly.
• A clean (maintenance) signal is transmitted when the detec-
tor's chamber sensitivity becomes degraded.
Note: If false alarms keep occurring, check whether the
detector's location is adequate. Relocate the unit as necessary.
Clean as described above.
Alarm Silencing
This smoke alarm is provided with an automatically resettable
alarm silencing feature. When the sensor is in alarm, by
pressing the Test/Silence/Reset button it will silence the local
annunciation of the alarm and transmit an alarm restoral event
to the control panel. The LED will flash every 8 seconds (for up
to 8 minutes) to indicate the alarm has been silenced. The
flashing LED will stop when the unit returns to normal
operation. The alarm silence feature has a fixed time setting
that desensitizes the smoke alarm for 8 minutes. The alarm
silencing does not disable the smoke alarm but rather reduces
its smoke sensitivity. Following the silenced period the smoke
alarm restores automatically to its intended operation. If smoke
around the unit is dense enough to suggest a potentially
dangerous situation, it will stay in alarm, or may return to the
alarm state quickly.
Owner’s Instructions
Fire Safety In The Home
Most fires occur in the home, and to minimize risk, it is
recommended that a household fire safety audit be conducted
and a family escape plan be developed.
Household Fire Safety Audit
1. Are all electrical appliances and outlets in safe condition?
Check for frayed cords, overloaded lighting circuits, etc. If
you are uncertain about the condition of your electrical appli-
ances or household service, have a professional evaluation.
2. Are all flammable liquids safely stored in closed containers,
and in a cool and well ventilated area? Cleaning the unit with
flammable liquids should be avoided.
3. Are hazardous materials (i.e., matches) out of the reach of
children?
4. Are furnaces and wood burning appliances properly
installed, clean, and in good working order? If in doubt,
have a professional evaluation.
Family Escape Planning
There is often very little time between the detection of a fire
and the time it becomes deadly. Because of this, it is very
important that a family escape plan be developed and
rehearsed.
• Every family member should participate in the escape plan.
• Study the possible escape routes from each location within
the house. Since many fires occur at night, special attention
should be given to the escape routes from sleeping quarters.
• It is essential that escape from a bedroom be possible with-
out opening the interior door. Consider the following when
making your escape plans:
• Ensure that doors and windows that open to the outside are
easily opened. Ensure that they are not painted shut and that
the locking mechanisms operate smoothly.
• If opening or using the exit is too difficult for children, the
elderly or handicapped, plans for their rescue should be
developed. This plan includes making sure that those who
are to perform the rescue can promptly hear the fire warning
signal.
• If the exit is above the ground level, an approved fire ladder
or rope should be provided, as well as training in its use.
• Exits on the ground level should be kept clear. Be sure to
remove snow from exterior patio doors in the winter and
that outdoor furniture or equipment does not block exits.
• The family should have a predetermined assembly point
where everyone can be accounted for; for example, across
the street or at a neighbor’s house.
• Once everyone is out of the house, call the Fire Department.
• A good plan emphasizes a quick escape. Do not investigate
first or attempt to fight the fire, and do not attempt to rescue
belongings or valuables as this takes up time. Once outside,
do not re-enter the house; wait for the Fire Department.
• Write the plan down and rehearse it frequently so that
should an emergency ever arise, everyone will know what
to do. Revise the plan as conditions change; for example,
when there are more or fewer family members in the home
or if there are changes to the house.
• Make sure your fire warning system is operational by con-
ducting weekly tests. If you are unsure about system opera-
tion, contact your smoke detector installer or dealer.
DSC recommends that you contact your local Fire Department
and request further information on home fire safety and escape
planning. If available, have your local fire prevention officer
conduct an in-house fire safety inspection.
