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).
