EQ2200UVIR UV/IR DETECTOR
INPUT VOLTAGE—
24 vdc nominal, 18 to 30 Vdc. 10% overvoltage will not
cause damage to the equipment.
INPUT POWER—
2.0 watts nominal, 5.0 watts maximum during
oi
test.
TEMPERATURE RANGE—
Operating:
–40°F to +167°F (–40°C to +75°C).
Storage:
–40°F to +185°F (–40°C to +85°C).
HUMIDITY RANGE—
0 to 95% RH. Can withstand 100% condensing
humidity for short periods of time.
SPECTRAL SENSITIVITY RANGE—
UV:
0.185 to 0.245 microns (solar blind).
IR:
4.45 microns (solar blind).
Figure X-7 illustrates the spectral response range of the
UV and IR sensors.
CONE OF VISION—
90 degree cone of vision using gasoline fuel (1 sq. ft).
80 degree cone of vision using methane fuel (30 inch).
See Figure X-8.
FLAME SENSITIVITY—
Refer to Tables X-1 and X-2 for typical detector
response characteristics.
CAUTION
The detector is extremely sensitive when the very
high setting is utilized. While this setting is
required to reliably detect certain types of fires,
care must be taken to minimize the possibility of
false alarms.
RESPONSE TIME—
Selectable for a 0 to 7 second time delay. Fastest
response time is 0.5 second.
OUTPUTS—
Digital communication, transformer isolated (78.5 k
bps).
VIBRATION—
Meets MIL SPEC 810C, method 514.2, curve AW.
ENCLOSURE MATERIAL—
Copper-free aluminum (red) or 316 stainless steel, with
stainless steel mounting bracket.
DIMENSIONS—
See Figures X-9 and X-10.
