SPECIFICATIONS
OPERATING VOLTAGE—
24 Vdc nominal (18 Vdc minimum, 30 Vdc maximum).
Maximum ripple is 2 volts peak-to-peak.
POWER CONSUMPTION—
Without heater: 4 watts at 24 Vdc nominal;
5.2 watts at 24 Vdc in alarm.
4.5 watts at 30 Vdc nominal;
6.5 watts at 30 Vdc in alarm.
Heater only: 8 watts maximum.
Total power: 17 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.
For HART model, refer to Addendum number 95-8613.
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.
Auxiliary relay, Form C, 5 amperes at 30 Vdc:
The auxiliary relay has normally open / normally
closed contacts, normally energized or de-energized
operation, and latching or non-latching operation.
CURRENT OUTPUT (Optional)—
0 to 20 milliampere (±0.3 mA) dc current, with a maximum
loop resistance of 500 ohms from 18 to 19.9 Vdc and 600
ohms from 20 to 30 Vdc.
LON OUTPUT (Optional) —
Digital communication, transformer isolated (78.5 kbps).
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 +125°C.
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
perfect cone of vision (full coverage at maximum
detection distance, both on and off axis) for hydrogen
and methanol flame detection.
Refer to Appendix A for FM Approved cone of vision data.
RESPONSE TIME—
Typical response times are under 10 seconds.
DIMENSIONS—
See Figure 19.
ENCLOSURE MATERIAL—
Copper-free aluminum (painted) or Stainless Steel (316/
CF8M Cast).
VIBRATION—
Conformance per FM 3260: 2000, MIL-STD 810C
(Curve AW).
