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.

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 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. During an alarm the LED will
flash 1/second and the sounder will sound the evacuation tempo­ral 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 recom­mendations.

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

Tab

Mounting Holes

Mount backplate on standard 4” octag­onal electrical box using the screws pro­vided.

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.

.

CAUTION: The dust cover protects the unit when not in service.
Remove the dust cover before use.

3. Wiring

Refer to the wiring diagrams in this installation sheet and those
provided in the Installation Manual of the alarm control panel
being used with the unit.

Before connecting the unit, prepare the wires from the electrical
box for connection; Do not use frayed or bent wire.

When wiring is completed, inspect the wiring and correct any
errors before applying power to the unit. When the wiring has
been thoroughly reviewed, neatly insert the wires into the electrical
box and secure the unit to the mounting plate.

the detector clockwise until the detec­tor snaps into place. Remove the side
tab from the locking tab to lock in
place (optional).

REMOVAL: If the side tab is removed
to lock the detector, depress tab with a small flat blade screwdriver
and rotate detector counter-clockwise until the alignment marks
line up. Remove detector.

5. Test Unit

Initiate test for units without a sounder by placing a magnet near
the LED/Test Button for greater than 5 seconds. Initiate test for
units with a sounder by pressing the test button for greater than 5
seconds.

Alarm activation is indicated by the LED, the sounder, and the
alarm reporting to the control panel. If the smoke detectors are
inter-connected using model PRM-4W and a detector is tested,
then all detectors will sound. The detector restores to normal when
the test button is released or when the magnet is removed.

NOTE: Allow a minimum of 20 seconds between test activations.
NOTE: If the detector is in one of the following states when a test is

initiated; it will not enter an alarm state.

1. Compensation trouble.

2. Failure of heat or smoke detector.

3. Other internal faults that could prevent a smoke or heat alarm.

NOTE: Smoke sensitivity of installed detectors can be measured
without removal or an alarm being generated using the FSD-100
Smoke Detector Test Meter.

Test Unit with FSD-100 Smoke Detector Test Meter

To test the unit using the FSD-100, set the test meter up to read
devices as per the instructions supplied with the test instrument.
Depress the test button (or place the FSD-100 on the outside edge
of the plastics beside the test button to activate the reed switch on
units without sounder) on the smoke detector for 1 second and
release.

NOTE: If the test button is held for 5 seconds or longer, an alarm will
be generated.

Move the test meter over the center of the detector, wait until you
hear the test meter beep, remove the unit and the information can
be immediately reviewed. Please see the instructions supplied with
the FSD-100 Smoke Detector Test Meter for more information.

6. Compensation Reset

Cleaning, replacement of the smoke sensor, or other changes may
change the background signal/noise of the detector; this requires
the drift compensation be reset. Compensation trouble is one of
the faults indicated when the LED indicator is OFF while the
sounder is chirping.

1. Remove power from the unit, then press and hold the test but­ton for 30 seconds to power down unit.

2. Power up unit while pressing the test button.The LED will
flash; when 5 seconds has elapsed. Release the test button
within 1 second after the fifth LED flash.

3. The LED will flash every 8 seconds for 1 minute. When the
detector stops flashing test the detector to verify normal oper­ation.
