FSA-410D Series Smoke Alarm
Installation and Operating Instructions
Read this instruction sheet thoroughly before installation and use of the FSA-410D Smoke Alarm
Piezo Sounder
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
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.
LED/Test Button
Alignment Marks
Do NOT locate smoke alarms at
the top of peaked or gabled ceil-
ings; 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.
PRM-4W to reverse the polarity of the 4-wire loop. This will acti-
vate 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 environmen-
tally 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.
