BEFORE YOU BEGIN
Carefully remove the unit from its factory packaging. Ex-
amine the FW-2S to identify the base, trim ring and detec-
tor head. Closely examine the base and locate terminals 2
and 5. The trim ring and detector head are turned counter-
clockwise to remove from the base. To ease installation,
raised alignment tabs are impressed into the base, trim ring
and detector head; take a moment to find these alignment
tabs (see Figs. 2 - 4).
SELECT THE SMOKE DETECTOR LOCATION
Referring to the NFPA standard that follows, select a suit-
able location to mount the FW-2S. As per UL listing re-
quirements, open-area smoke detectors are intended for
mounting on a ceiling no less than 6 inches from a wall or
mounting on a wall no less than 4 inches and no more than
12 inches from a ceiling.
INSTALLING THE FW-2SBASE
The smoke detector base can be mounted directly onto an
electrical junction box such as an octagonal (3", 3.5" or 4"),
round (3"), or square (4" length) box without using any type
of mechanical adapter.
1. Use the two screws and anchors provided to attach
the base to the wall or ceiling. NOTE: Do not install
on removable surfaces such as ceiling tiles.
2. To ensure proper installation of the detector head to
the base, all wires should be properly addressed at
installation. Position all wires flat against terminals
and fasten the wires away from connector terminals.
INSTALLING THE FW-2SHEAD
Do not install the detector head until the installation area is
thoroughly cleaned of construction debris, dust, etc. If you
used a jumper wire to short terminals 2 and 5 when testing
the detector loop continuity, ensure the jumper wire is
removed prior to installing the detector head.
1. Align the detector head Alignment Tab shown in Fig. 3
with the Short Alignment Tab shown in Fig. 2.
2. Mate the detector head onto the base and twist clock-
wise until it securely locks into place. The detector
head Alignment Tab shown in Fig. 3 must align with
the Long Alignment Tab shown in Fig. 2.
INSTALLING THE TRIM RING
The trim ring covers the mounting screws and base. Note:
The trim ring can be installed before or after the detector
head.
1. Align the trim ring Alignment Tab shown in Fig. 4 any-
where within the Notch shown in Fig. 2.
2. Press in and mate the trim ring onto the base and twist
clockwise until it securely locks into place.

TESTING THE UNIT (Test Weekly)
1. All central station services, releasing devices and ex-
tinguisher systems must be disengaged during the test
period and must be re-engaged immediately after test-
ing.
2. After energizing the detector head for approximately
one minute, check to see the indicator two red LED's
flashing once every 7-10 seconds. If red LED fails to
flash, it indicates a non-functioning detector or faulty
wiring. Re-check the wiring or replace the detector if
necessary.
3. Position the "Test Magnet" against the side of the de-
tector housing marked "TEST" for at least 5 seconds.
The detector should trigger an alarm (as indicated by a
rapidly flashing red LED light and siren sounding). Re-
set the control unit to return to normal operation.
4. Allow smoke from a cotton wick or punk to enter the
detector-sensing chamber for at least 5 seconds.
When sufficient smoke has entered the chamber, an
alarm signal will be triggered (as indicated with a con-
tinuous red LED light). After alarm is triggered, reset
each detector and/or control unit before attempting to
test additional detectors in the same zone. If the alarm
fails to trigger an alarm, it indicates a defective unit.
CLEANING THE UNIT
MAINTENANCE WARNING
The smoke detector will warn that it must be cleaned when
the unit flashes the red LED every 5 seconds and the unit
does not pass the weekly test by the user (see TESTING
THE UNIT at left). To clean the smoke detector, vacuum the
outside of the unit at least once a year (preferably every six
months) using a soft brush attachment. Do not attempt to
clean the unit in any other way. If this maintenance proce-
dure fails to clean the unit sufficiently, call for service and/or
replace the unit.

NFPA STANDARD FOR SMOKE-DETECTOR LOCATION
The FIREWOLF FW-2S should be installed in accordance with the National Fire
Protection Association (NFPA) Standard 72. For your information, the National Fire
Protection Association's Standard 72, reads as follows:
11.5.1 One- and Two-Family Dwelling Units.
11.5.1.1 Smoke Detection Where required by applicable laws, codes, or standards
for the specified occupancy, approved single- and multiple-station smoke alarms shall
be installed as follows: (1) In all sleeping rooms. Exception: Smoke alarms shall not
be required in sleeping rooms in existing one- and two- family dwelling units. (2) Out-
side of each separate sleeping area, in immediate vicinity of the sleeping rooms. (3)
On each level of the dwelling unit, including basements. Exception: In existing one-
and two-family dwelling units, approved smoke alarms powered by batteries are per-
mitted.
11.8.3 Are More Smoke Detectors Desirable? The required number of smoke de-
tectors might not provide reliable early warning protection for those areas separated by
a door from the areas protected by the required smoke detectors. For this reason, it is
recommended that the householder consider the use of additional smoke detectors for
those areas for increased protection. The additional areas include the basement, bed-
rooms, dining room, furnace room, utility room, and hallways not protected by the re-
quired smoke detectors. The installation of smoke detectors in kitchens, attics (finished
or unfinished), or garages is not normally recommended, as these locations occasion-
ally experience conditions that can result in improper operation.
There exist certain situations where the presence of a smoke alarm is not effective,
such as smoking in bed, the testing of gas leaks with a flame or for warning against the
existence of high carbon monoxide levels inside a family living unit. Current studies
have shown smoke alarms may not awaken all sleeping individuals; it is therefore 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 and to
provide assistance to those who may be incapable of safely evacuating the area unas-
sisted.
For family living units with one or more split levels (i.e., adjacent levels with less than
one full story separation between levels), a smoke detector required as above shall
suffice for an adjacent lower level, including basements.
Exception: Where there is an intervening door between one level and the adjacent
lower level, a smoke detector shall be installed on the lower level.
•Ceiling-mounted smoke alarms should be located in the center of the room or hall,
or not less than 4 inches from any wall. When the detector is mounted on a wall,
the top of the detector should be 4 to 12 inches from the ceiling.
•Do not install smoke alarms where normal ambient temperatures are above 100°F
(37.8°C), below 40°F (4.4°C) or greater than 92% humidity unless the alarm has
been determined to be capable of being used at installation points with higher or
lower ambient temperatures. Also, do not locate alarm in front of air conditioners,
heating registers, or other locations where normal air circulation will keep smoke
from entering the detector. Installing smoke detectors in kitchens, garages or
furnace rooms is NOT recommended.
All installation wiring must be in accordance with the provisions of Article 210 of the
National Electrical Code, ANSI / NFPA 70. All protected premises fire alarm systems
shall be maintained and tested (at least once every month) in accordance with NFPA
72.
FIRE PREVENTION AND ESCAPE
The purpose of an early warning smoke alarm is to detect the presence of fire in its
early stages, and sound an alarm giving the occupants more time to exit the premise
before the smoke reaches a dangerous concentration level.
Fires start even with the best of housekeeping and fire-prevention procedures. Fire is
an unexpected event. Early warning detection alerts occupants in time to act.
KNOW FIRE HAZARDS. No detection device can protect life in all situations.
Therefore, safeguards should be taken to avoid such potentially dangerous situations
as smoking in bed, leaving children home alone, cleaning with flammable liquids such
as gasoline.
The best fire protection is minimizing fire hazards through proper storage of materials
and general good housekeeping techniques. A cluttered basement, attic, or other
storage area is an open invitation to fire.
Careless use of combustible materials and electrical appliances, or overloading of
electrical outlets are other prime causes in starting fires.
It is most important that explosive and/or fast-burning materials be eliminated from the
home if at all possible. Even after proper precautions have been taken, fires can start.
Be prepared.
IN CASE OF FIRE. Leave immediately. Don’t stop to pack or search for valu-
ables. In heavy smoke, hold your breath and stay low -- crawl if necessary. The clear-
est air is usually at the floor.
If you have to go through a closed door, carefully feel the door and door knob to see if
undue heat is present. If they seem relatively cool, brace your foot against the bottom
of the door with your hip against the door and one hand against the top edge. Open it
slightly. If a rush of hot air is felt, slam the door quickly and latch it. Unvented fire
tends to build up considerable pressure. Be sure all the household realizes and under-
stands this danger.
Use your neighbor’s phone or a street fire alarm box. The job of extinguishing the fire
should be left to the professionals. Too many unforeseen things can occur when inex-
perienced people try to extinguish afire.
BE PREPARED. Perform fire drills regularly. Use them to assure recognition of
an alarm signal. For your protection, simulate different circumstances (smoke in hall, in
living room, etc.). Then have everyone react to the situation.
Draw a floor plan and show two exits from each room. Frequently, a knotted rope or
ladder from a window will serve this purpose. It is important that children be instructed
carefully, because they tend to hide in times of crisis.
It is imperative that one meeting place outside the home be established. You should
insist that everyone meet there during an alarm. This will eliminate the tragedy of
someone reentering the house for a missing member who is actually safe.
If you have children and/or invalids residing in your household, you can help your fire
department. Most fire departments have window decals available for use in children’s
or invalid’s bedrooms. Properly used, these decals will quickly identify sleeping quar-
ters of these individuals and show the department where to look first for members of
your household.
