NAPCO FW-4, FW4-H, FW-2, FW2-H Installation Instruction

INSTALLATION INSTRUCTIONS

FW4-H and FW2-H

These installation instructions are for the FW-4, FW4-H, FW-2 and the FW2-H FIREWOLF Smoke Detectors.

CAUTION!!!

Install this and all life safety devices in accordance with
applicable NFPA standards, local codes, and the au­thorities having jurisdiction. Failure to follow these in­structions may result in failure of the detector to initiate
an alarm condition. Napco Security Systems, Inc. and
the original equipment manufacturer, are not respon si­ble for detectors that have been improperly installed,
tested, or maintained.

For testing and cleaning information, refer to these in­structions and/or call the NAPCO fax request line at
[phone]. Also refer to NFPA-72 Chapter 5 for
Automatic Fire Detectors for installation guidelines and
Chapter 7 for testing and maintenance requirements.

Use “3M” Weatherban # 606 non-flammable sealing
compound to seal field wiring conduit openings in the
mounting back box. Compliance with this request may
reduce the occurrence of the “STACK EFFECT”.

R

To mount the FW- 4 and the FW-2 Basel es s Det ec tor
Head to the Trim Rin g, d o th e foll o win g:

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 j ust UNDER the word “TEST” as shown on Diagram 2A.

2. The detector should alarm within 10 seconds (If control panel is programmed for

HOLD

MAGNET

HERE

Fire Alarm Verification, it may take up to 30 seconds).

3. The detector’s LEDs should be on Red continuously and any control panel indi­cating 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.

DIAGRAM 2A

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 bo th 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 bo t h L EDs are on Red cont inuously.

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 follow­ing instructio ns for cleaning info rmation:

MANUAL CLEANING PROCEDURE

Tools you will need:

2 small screwdrivers (1/8” wide)

∗

A small soft-bristled artist’s pai nt brush

∗

Denatured alcohol

∗

Clean dry compressed air.

∗

Use only lint-free materials when cleaning the chambers of the photoelectric smoke detector. Use of fibrous materials may result in

NOTE:

false alarms.

Remove and Disassemble the Detect or

Follow the steps in this section to prepare the detector for cleaning:

1. Remove the detector from the trim ring.

2. Disassemble det ector by placing o ne screwdriver under the tab as shown in Diagram 2B (above).

3. Then place the se cond screwdriver under the next adjacent TAB pushing it the direction show n in Diagram 2B.

4. Push the screwdri ver outward from the center of the detect or and lift the Enclosure upward.

5. Do the same with the second screwdriver, but do not remove it--keep it in place.

6. Ta ke 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 t he Chamber Cover counter-clockwise until the
Cover Tabs clear the Tab Catches. Lift and separate the Cham ber 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 re­maining 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 Ali gnment 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 Co ver of the detector nose down on a flat s urface.

5. Align the Outer Cover Nub with the Alignment Arrow on the enclosure (two Orien­tations are pos sible, 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 dete ctor will s nap into the Outer C over. Th e de tec­tor 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.

If after testing, the detector is not working within the prescribed limits, then

Note:

return it to the manufacturer for servicing.
