Read this instruction sheet thoroughly before installation and use of the
FSA-410 4-Wire Smoke Detector. This instruction sheet is intended to be used
with the Installation Manual of the alarm control panel. All the instructions spec-
ified within that manual must be observed.
Introduction
The FSA-410 is a 4-wire photoelectric smoke detector with the
following available options: fixed temperature
and rate of rise
heat detector, internal piezoelectric alarm, auxiliary form C
relay, and/or remote LED output. Three versions are available:
US version (UL), Canadian version (ULC) and an International
version (EU).
NOTE:
Heat detection based on rate of rise has not been
investigated by UL/ULC.
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 siren 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 acti-
vates the alarm relay to send the alarm signal to the control
panel. During an alarm the LED will flash once per second and
the siren will sound the the evacuation temporal pattern.
Remote Alarm - Interconnection
Multiple detectors (with sirens) 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 sirens of all units connected
on the loop. Refer to the PRM-2W/4W Installation Instructions
for installation details.
Smoke - Drift Compensation
The detector automatically compensates for long-term
environmentally induced changes to maintain a constant
smoke sensitivity. 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. The detector will
also go into heat alarm if there is a rapid increase in the tem-
perature over a short period of time. During an alarm the LED
will flash once per second and the siren will sound the evac-
uation temporal pattern.
Alarm Indications
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 recommendations.
Do
NOT
locate smoke detectors at the top of peaked or
gabled ceilings; the dead air space in these locations may pre-
vent the unit from detecting smoke. Avoid areas with turbu-
lent air flow, (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).
