Introduction
The FSA-210 is a 2-wire photoelectric smoke detector with
optional: fixed temperature heat detector, internal piezoelectric
alarm, auxiliary form C relay, and/or remote LED output. Three
version are available: US version (UL), Canadian version (ULC)
and an International version (EU).
Operation
Approximately every 7 to 8 seconds the unit tests for a smoke or
heat alarm condition. During this sequence the unit also per-
forms 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 send
the alarm signal to the control panel. During an alarm the LED
will flash 1/second and the sounder will sound the the evacua-
tion temporal pattern (UL, EU) or continuous beeps (ULC).
Remote Alarm - Interconnection
Multiple detectors (with sounders) can be connected using the
PRM-2W Polarity Reversal Module. When a fire alarm occurs,
the panel will signal the PRM-2W to reverse the polarity of the
2-wire loop. This will activate the sounders of all units con-
nected on the loop. Refer to the PRM-2W/4W Installation
Instructions for installation details.
Smoke - Drift Compensation
The detector automatically compensates for long-term environ-
mentally induced changes to maintain a constant smoke sensi-
tivity. 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 tem-
poral pattern (UL, EU) or continuous beeps (ULC).
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, Chap-
ter 11 CAN/ULC-S553-02 or other appropriate national stan-
dards 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, (near doors, fans or win-
dows. 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).
