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
95-8577.
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. It is configurable for energized
or de-energized operation and latching or non-
latching operation to perform as a secondary relay
for fire alarm or fault.
CURRENT OUTPUT (OPTIONAL)—
0–20 milliampere (±0.3 mA) dc current, with a
maximum loop resistance of 500 ohms from 18–
19.9 Vdc and 600 ohms from 20–30 Vdc.
LON OUTPUT—
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—
0–95% 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. Unlike conventional detectors, the X3301
provides full coverage at a minimum of 70% of
the maximum detection distance.
Perfect cone of vision for methane fire detection
— 100 feet (30.5 m) on and off axis on “very high”
setting.
Refer to Appendix A for FM Approved cone of
vision data.
RESPONSE TIME—
Typical response times are under 10 seconds.
Models are available that can respond to
automotive paint gun fires in under 0.5 seconds.
See Appendix A and the Automotive Addendum,
number 95-8534, for actual response times.
