Introduction
The FSA-410 is a 4-wire photoelectric smoke detector with
optional: fixed temperature heat detector, internal piezoelectric
alarm, auxiliary form C relay, and/or remote LED output. Three
versions are available: US UL, Canadian ULC and International
(EU).
Operation
Approximately every 7 to 8 seconds the unit tests for a smoke or
heat alarm condition. During this sequence the unit also performs
self diagnostics, and checks for faults. During normal operation
the LED will flash every 50 seconds and the sounder will not
sound.
Smoke Alarm
The smoke detector has a nominal fixed alarm sensitivity (refer to
the
Specifications
on the last page) and it will go into alarm when
the signal level exceeds the 'alarm' threshold and activate the
alarm relay to send the alarm signal to the control panel. During
an alarm the LED will flash 1/second and the sounder will sound
the the evacuation temporal pattern.
Remote Alarm - Interconnection
Multiple detectors (with sounders) can be connected using the
PRM-4W Polarity Reversal Module. When a fire alarm occurs, the
panel will signal the PRM-4W to reverse the polarity of the 4-wire
loop. This will activate the sounders of all units connected on the
loop. Refer to the PRM-2W/4W Installation Instructions for instal-
lation details.
Smoke - Drift Compensation
The detector automatically compensates for long-term environ-
mentally induced changes to maintain a constant smoke sensitiv-
ity. When the drift compensation has reached its high or low limit
of adjustment, the detector will go into the trouble state.
Heat Alarm
The heat detector will go into alarm when the heat signal level
exceeds the heat alarm threshold (135ºF/57ºC); and send the
alarm signal to the control panel. During an alarm the LED will
flash 1/second and the sounder will sound the evacuation tempo-
ral pattern.
Installer Instructions
1. Smoke Detector Placement
On smooth ceilings, detectors
may be spaced 9.1M (30 feet)
apart as a guide. Other spacing
may be required depending on
ceiling height, air movement, the
presence of joists, uninsulated
ceilings, etc. Consult National Fire
Alarm Code NFPA 72, Chapter 11
or other appropriate national
standards for installation recom-
mendations.
Do
NOT
locate smoke detectors
at the top of peaked or gabled
ceilings; the dead air space in these locations may prevent the
unit from detecting smoke. Avoid areas with turbulent air flow,
such as near doors, fans or windows. Rapid air movement around
the detector may prevent smoke from entering the unit.
Do
NOT
locate detectors in areas of high humidity.
Do
NOT
locate detectors in areas where the temperature rises
above 38ºC (100ºF) or falls below 5ºC (41ºF).
Install Smoke detectors in accordance with NFPA 72, Chapter 11
.
“Smoke detectors shall be installed outside of each sleeping area
in the immediate vicinity of the bedrooms and on each additional
story of the family living unit, including basements and excluding
crawl spaces and unfinished attics. In new construction, a smoke
detector also shall be installed in each sleeping room”.
2. Mount Smoke Detector Backplate
Mount backplate on standard 4” octag-
onal electrical box using the screws pro-
vided.
NOTE:
Power supply must be supplied
from a UL/ULC Listed alarm control unit.
Install wiring in accordance with the
appropriate national and local electrical
codes.
