Introduction
The FSA-410D is a 4-wire photoelectric smoke alarm with
optional: fixed temperature heat detector, auxiliary form C relay,
and/or remote LED output.
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 remain on to indicate energization of the unit and the
sounder will not sound.
Smoke Alarm
The smoke detector has a nominal fixed alarm sensitivity (refer to
Specifications on back page) and it will go into alarm when the
signal level exceeds the 'alarm' threshold. During an alarm the
LED will shut off, the sounder will sound continuous beeps and
the alarm relay will be activated.
Remote Alarm - Interconnection
Multiple alarms can be connected using the PRM-4W Polarity
Reversal Module. When a fire alarm occurs, the unit 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 Manual for installation details.
Smoke - Drift Compensation
The unit 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 unit 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). During an alarm
the LED will shut off. The sounder will sound continuous beeps
and the alarm relay will be activated.
Alarm Restore
When the smoke clears from the unit and the heat signal falls
below the ‘restore’ level, the unit will automatically reset itself.

Installer Instructions
1. Smoke Alarm Placement
On smooth ceilings, units may be spaced 9.1m (30 ft) apart as a
guide. Other spacing may be required depending on ceiling
height, air movement, the presence of joists, uninsulated ceilings,
etc. Refer to CAN/ULC-S553-02 for installation recommendations.
Do NOT locate smoke alarms 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 units in areas of
high humidity.
Do NOT locate units in areas where the temperature rises above
38ºC (100ºF) or falls below 5ºC (41ºF).
2. Mount Smoke Alarm Backplate
Locking
Tab
Mounting Holes
Mount backplate on standard 4” octagonal electrical box using the screws provided.
NOTE: Power must be supplied from a
ULC Listed power supply or alarm control unit auxiliary output. 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.

rotating 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 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.
