FW-2S Wiring Diagram
Connect wiring to the bases as shown in
the wiring diagram at right.
CAUTION:
Do not mix smoke detec-
tor types or dry contact closure de-
vices (including thermal detectors,
pull station or water flow devices) on
the same zone
.
CAUTION: Connect wiring to termi-
nals as shown. Do not loop wire un-
der terminals. Break wire run to pro-
vide supervision.
ADDITIONAL CAUTIONS:
●
Do not use looped wire under ter-
minals 2 and 5. Break wire run to
provide supervision of connec-
tions.
●
Do not attempt to disassemble
this factory-sealed smoke detec-
tor. The detector is not intended
to be opened for servicing.
Opening the detector head will
void the warranty.
●
To prevent detector contamina-
tion and subsequent warranty
cancellation, smoke detector must remain covered until installation area is clean and dust free.
●
See the FACP installation instructions for the maximum number of detectors permitted per zone and for specific wiring
terminal numbers.
●
Not suitable for installation in areas where air velocities exceed 300 ft/min.
●
Ensure the end-of-line device shown in Fig. 1 (and 1a) is compatible with the control panel.

with internal sounder,
FW-2SHEAD
and
FW-2SBASE
.
CAUTION
Install this and all life safety devices in accordance with
applicable NFPA standards, local codes, and the authori-
ties having jurisdiction. Failure to follow these instructions
may result in failure of the detector to initiate an alarm con-
dition. Napco Security Systems, Inc. and the original
equipment manufacturer, are not responsible for detectors
that have been improperly installed, tested, or maintained.
For testing and cleaning information, refer to these instruc-
tions and/or call the NAPCO fax request line at (631) 842-

open-area smoke detectors. Duct smoke detectors are solely intended for use in the air handing equipment for such pur-
poses like dampers or shutting down the air handing units.
