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 au-
thorities having jurisdiction. Failure to follow these in-
structions may result in failure of the detector to initiate
an alarm condition. Napco Security Systems, Inc. and
the original equipment manufacturer, are not responsi-
ble for detectors that have been improperly installed,
tested, or maintained.
For testing and cleaning information, refer to these in-
structions and/or call the NAPCO fax request line at
(631) 842-3291. 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”.
