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 oi testing.
• Easily replaceable oi plate.
• Fire and fault relays.
• A tri-color LED on the detector faceplate indicates

normal condition and notifies personnel of fire alarm

or fault conditions.

• Operates under adverse weather conditions.
• Mounting arm 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.
