Mounting; Testing; Cleaning; Remove And Re/Disassemble - FIREWOLF FW2-H Installation Instructions

To mount the FW- 4 and the FW-2 Baseless Detector
Head to the Trim Ring, do the following:
1. Place the Baseless Detector Head over the Trim Ring with
its back towards the Trim Ring.
2. Place the detector with the Alignment Mark at Alignment
Position 1 (see diagram).
3. Bring the detector together with the Trim Ring.
4. Turn the detector clockwise and when the Alignment Mark
is at Alignment Position 2 the detector will have snapped
into place (see diagram).
5. Refer to the diagram for visual reference to the alignment
marks.
TESTING THE FW- 4 and the FW-2 INSTALLATION
For go/no-go testing, a magnet will be required.
1. Hold the magnet just UNDER the word "TEST" as shown on Diagram 2A.
2. The detector should alarm within 10 seconds (If control panel is programmed for
Fire Alarm Verification, it may take up to 30 seconds).
3. The detector's LEDs should be on Red continuously and any control panel indi-
cating appliances should activate.
4. Silence the system and activate the control panel reset to reset smoke detector.
5. The smoke detector LEDs should flash Green.
FIREWOLF SENSITIVITY TEST FEATURE and INSTALLATION VERIFICATION
Note: The FW- 4 and the FW-2 have a built-in automatic sensitivity test feature that will automatically indicate a change in sensitivity.
1. In normal condition both LEDs flash Green.
2. When the sensitivity drifts outside of its sensitivity limits, both LEDs flash Red (e.g., when the unit needs cleaning).
3. In the alarm state both LEDs are on Red continuously.
4. When the condition exists as stated in 2 above, the device needs to be cleaned or returned to the factory for servicing. Refer to the follow-
ing instructions for cleaning information:
MANUAL CLEANING PROCEDURE
Tools you will need:
2 small screwdrivers (1/8" wide)
A small soft-bristled artist's paint brush
Denatured alcohol
Clean dry compressed air.
NOTE: Use only lint-free materials when cleaning the chambers of the photoelectric smoke detector. Use of fibrous materials may result in
false alarms.
Remove and Disassemble the Detector
Follow the steps in this section to prepare the detector for cleaning:
1. Remove the detector from the trim ring.
2. Disassemble detector by placing one screwdriver under the tab as shown in Diagram 2B (above).
3. Then place the second screwdriver under the next adjacent TAB pushing it the direction shown in Diagram 2B.
4. Push the screwdriver outward from the center of the detector and lift the Enclosure upward.
5. Do the same with the second screwdriver, but do not remove it--keep it in place.
6. Take the first screwdriver and place it under the third TAB adjacent to the second TAB. Push the TAB outward and lift
the Enclosure upward.
7. With three tabs freed, the Enclosure will finally remove easily with the application of the screwdriver.
Clean the Detector
CAUTION: Do not attempt to remove the insect screen.
1. Remove the Outer Cover of the detector as specified and set aside.
2. Place the detector in the palm of your left hand and grasp the Chamber Cover
with your right hand. Twist the Chamber Cover counter-clockwise until the
Cover Tabs clear the Tab Catches. Lift and separate the Chamber Cover and
Outer Cover from the Optical Unit.
3. Swab the Optical unit with denatured alcohol using a small soft-bristled brush.
4. Use dry clean compressed air to dry the optical unit and to remove any re-
maining particles.
5. Clean the Chamber Cover and Outer Cover in the same manner.
Reassemble the Detector
1. Locate the Alignment Arrows on both the Chamber Cover and the Optical Unit.
2. Set the Chamber cover onto the Optical Unit while making sure that Alignment
Arrow 1 and Alignment Arrow 2 are aligned with each another.
3. Holding the detector in your left hand and grasping the Chamber Cover with your
right hand, rotate the Chamber Cover clockwise until the Cover Tabs snap into the
Tab Catches.
4. Place the Outer Cover of the detector nose down on a flat surface.
5. Align the Outer Cover Nub with the Alignment Arrow on the enclosure (two Orien-
tations are possible, only one will fit properly).
6. With the Outer Cover Nub aligned with the Alignment Arrow, press down firmly on
the back of the detector. The detector will snap into the Outer Cover. The detec-
tor is now ready to be returned to the Trim Ring from which it was removed.
7. The detector should be re-tested by performing the test procedure described in
this document.
Note: If after testing, the detector is not working within the prescribed limits, then
return it to the manufacturer for servicing.
