fEaTURES
• Responds to a fire in the presence of modulated
blackbody radiation (i.e. heaters, ovens, turbines)
without false alarm.
• High speed capability — 30 milliseconds.
• Built-in data logging / event monitoring, up to 1500
events (up to 1000 general, 500 alarms).
• Pulse output for compatibility with controller based
systems.
• Microprocessor controlled heated optics for
increased resistance to moisture and ice.
• Automatic, manual or magnetic optical integrity (

)
testing.
• Easily replaceable
oi
plate.
• Fire and fault relays.
• A tricolor LED on the detector faceplate indicates
normal condition and notifies personnel of fire alarm
or fault conditions.
• Operates under adverse weather conditions.
• Mounting swivel allows easy sighting.
• Integral wiring compartment for ease of installation.
• Explosion-proof/flame-proof detector housing. Meets
FM, CSA, ATEX and CE certification requirements.
• Class A wiring per NFPA-72 (relay connections).
(Pulse output is equivalent to class A when detectors
are installed in a redundant configuration).
• 3 year warranty.
• Advanced signal processing (TDSA).
• RFI and EMC Directive Compliant.
SPECIfICaTIONS
OPERATING VOLTAGE—
24 Vdc nominal (18 Vdc minimum, 30 Vdc maximum).
Maximum ripple is 2 volts peak-to-peak.
For CSA compliance, the power source must
utilize a SELV (Safety Extra Low Voltage) or Class
2 style power supply.
POWER CONSUMPTION—
Without heater: 2.1 watts at 24 Vdc nominal;
3.5 watts at 24 Vdc in alarm.
2.2 watts at 30 Vdc nominal;
4.0 watts at 30 Vdc in alarm.
Heater only: 8 watts maximum.
Total power:
16.5 watts at 30 Vdc with EOL resistor
installed and heater on maximum.
EOL resistor must be ceramic, wirewound type, rated
5 watts minimum, with actual power dissipation not to
exceed 2.5 watts.
POWER UP TIME—
Fault indication clears after 0.5 second; device is ready
to indicate an alarm condition after 30 seconds.
OUTPUT RELAYS—
Fire Alarm relay, Form C, 5 amperes at 30 Vdc:
The Fire Alarm relay has redundant terminals and
normally open / normally closed contacts, normally
de-energized operation, and latching or non-
latching operation.
Fault relay, Form A, 5 amperes at 30 Vdc:
The Fault relay has redundant terminals and
normally open contacts, normally energized
operation, and latching or non-latching operation.
TEMPERATURE RANGE—
Operating: –40°F to +167°F (–40°C to +75°C).
Storage:
–67°F to +185°F (–55°C to +85°C).
Hazardous location ratings from -55°C to +75°C available
on flameproof model.
HUMIDITY RANGE—
0 to 95% relative humidity, can withstand 100%
condensing humidity for short periods of time.
CONE OF VISION—
The detector has a 90° cone of vision (horizontal) with
the highest sensitivity lying along the central axis.
See Figure 15.
RESPONSE TIME—
32 inch methane plume: < 10 seconds.
1 foot x 1 foot n-Heptane: < 15 seconds.

DISTANCE
(PERCENT)
100% REPRESENTS THE MAXIMUM DETECTION DISTANCE FOR A
GIVEN FIRE. THE SENSITIVITY INCREASES AS THE ANGLE OF
INCIDENCE DECREASES.
