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”.

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.

Owners Instructions

Fire Safety In The Home

Most fires occur in the home, and to minimize this danger, it is rec­ommended that a household fire safety audit be conducted and a
family escape plan be developed.

Household Fire Safety Audit

1. Are all electrical appliances and outlets in safe condition?
Check for frayed cords, overloaded lighting circuits, etc. If you
are uncertain about the condition of your electrical appliances
or household service, have a professional evaluation.

2. Are all flammable liquids safely stored in closed containers, and
in a cool and well ventilated area? Avoid cleaning the unit with
flammable liquids.

3. Are hazardous materials such as matches out of the reach of
children?

4. Are furnaces and wood burning appliances properly installed,
clean, and in good working order? If in doubt, have a profes­sional evaluation.

Family Escape Planning

There is often very little time between the detection of a fire and
the time it becomes deadly. Because of this, it is very important
that a family escape plan be developed and rehearsed.

• Include every family member when developing the escape plan.

• Study the possible escape routes from each location within the
house. Since many fires occur at night, give special attention to
the escape routes from sleeping quarters.

• It is essential that escape from a bedroom be possible without
opening the interior door. Consider the following when making
your escape plans:

• Ensure that doors and windows that open to the outside are
easily opened. Ensure that they are not painted shut and that
the locking mechanisms operate smoothly.

• Develop specific rescue plans if opening the exit or using the
exit is too difficult for children, the elderly or handicapped. This
plan includes making sure that those who are to perform the
rescue can promptly hear the fire warning signal.

• If the exit is above the ground level, provide an approved fire
ladder or rope, as well as training in its use.

• Keep exits on the ground level clear. Be sure to remove snow
from exterior patio doors in the winter and that outdoor furni­ture or equipment does not block exits.

• Have a predetermined assembly point where everyone can be
accounted for; for example, across the street or at a neighbor’s
house.

• Once everyone is out of the house, call the Fire Department.

• A good plan emphasizes a quick escape. Do not investigate first
or attempt to fight the fire, and do not attempt to rescue
belongings or valuables as this takes up time. Once outside, do
not re-enter the house; wait for the Fire Department.

• Write the plan down and rehearse it frequently so that should
an emergency ever arise, everyone will know what to do. Revise
the plan as conditions change; for example, when there are
more or fewer family members in the home or if there are
changes to the house.

• Make sure your fire warning system is operational by conduct­ing weekly tests. If you are unsure about system operation, con­tact your smoke detector installer or dealer.

• DSC recommends that you contact your local Fire Department
and request further information on home fire safety and escape
planning. If available, have your local fire prevention officer con­duct an in-house fire safety inspection.

Testing Your Smoke Detector

Follow the test procedure described here or contact your smoke
detector dealer or installer for testing instructions.

DSC recommends that you test the entire alarm system at least
once a week to verify the operation of all system functions.

Units with Sounder - Pushbutton switch

To test the smoke detector, press and hold the test button on the
front of the unit for 5 seconds minimum, the sounder initiates a
clicking noise during this time. When the button is pressed, the
unit’s alarm will sound and an alarm will be sent to the control
panel. When the button is released, the alarm will cease.

Units without Sounder - Magnet activated switch

To test the smoke detector, place a magnet adjacent to the test
button on the front of the unit (see Fig. 1) and hold in place for 5
seconds minimum. When the magnet is in place, the internal reed
switch will activate and an alarm will be sent to the control panel.
When the magnet is removed, the alarm will cease.

Upon completing the functional testing of the smoke detector,
check the unit’s sensing chamber to ensure proper operation. To
test the sensing chamber, wave a lit cotton wick or punk stick
around the outside of the unit until a generous amount of smoke
enters the sensing chamber or the unit alarms. If the smoke detec­tor does not function properly, call your smoke detector installer or
dealer for service.

Maintenance

The smoke detector is designed to require minimum maintenance.
If the case becomes dusty, vacuum with a small brush attachment.
If the case is greasy, wipe the case gently with a soft cloth slightly
dampened with soapy water.

Never disassemble the smoke detector; there are no user service­able parts inside the unit. Never paint the unit. Paint may prevent
smoke from entering the unit. If you are planning renovations or
repainting, contact your installer and ask that the unit be tempo­rarily removed until work is complete.

If the unit is located in an area where it is exposed to high levels of
dust or insects and causes false alarms, it may require service; con­tact your smoke detector installer or dealer.

Smoke Detectors

Smoke detectors that are a part of this system may not properly alert occupants of a fire for a num­ber of reasons, some of which follow. The smoke detectors may have been improperly installed or
positioned. Smoke may not be able to reach the smoke detectors, such as when the fire is in a chim­ney, walls or roofs, or on the other side of closed doors. Smoke detectors may not detect smoke
from fires on another level of the residence or building.

Every fire is different in the amount of smoke produced and the rate of burning. Smoke detectors
cannot sense all types of fires equally well. Smoke detectors may not provide timely warning of
fires caused by carelessness or safety hazards such as smoking in bed, violent explosions, escaping
gas, improper storage of flammable materials, overloaded electrical circuits, children playing with
matches or arson. Even if the smoke detector operates as intended, there may be circumstances
when there is insufficient warning to allow all occupants to escape in time to avoid injury or death.

WARNING: Digital Security Controls Ltd. recommends that the entire system be completely
tested on a regular basis. However, despite frequent testing, and due to, but not limited to,
criminal tampering or electrical disruption, it is possible for this product to fail to perform as
expected.
