DESCRIPTION
The IRC90H fire detectors and UxF-IR fire controllers provide fast, reliable flam e detection in a wide
variety of applications. The m icroprocessor based controllers (U4F pictured above) are available in one,
two or four channel versions which are the U1F, U2F and U4F. The system uses the Autom atic Visual
Integrity (vi) feature, which provides a continuous check of detector optical surfaces, detector sensitivity,
and electronic circuitry of the detector/controller system . Autom atic fault identification m onitors the system
for proper operation and provides a digital display of system status using a num erical code. Controller
response includes actuation of three or four relays for direct control of field response devices, one or two 4
to 20m A current outputs, a full array of faceplate indicators.
CONTROLLER SPECIFICATIONS
<
Operating Voltage:
24 Volts DC. Device can operate between 18 and 32 Volts DC
<
Pow er Consumption (controller only):
2.4 watts nom inal, 4.4 watts m axim um
100 m A nom inal, 180 m A m axim um at 24 Volts DC
Maxim um start-up current is 1.5 Am peres for 10 m illiseconds. Power supplies with fold
back current lim iting are not recom m ended
<
M aximum Ripple:
Ripple should not exceed 5 Volts peak-to-peak. The sum of DC plus ripple m ust be
$18 Volts DC and #32 Volts DC
<
Temperature Range:
Operating:
-40ºC to +85ºC
(-40ºF to +185ºF)

Storage:
-55ºC to +150ºC
(-65ºF to +302ºF)
<
Relay Contacts:
Form C Norm ally open/norm ally closed contacts rated for 5 Am peres at 30 Volts DC/ 250
Volts AC
<
Current Outputs:
One or two 4-20m A DC current, with a m axim um external loop resistance of 600 Ohm s at
18-32 Volts DC

Shipping W eight (approxim ate):
6 lbs (2.7 kg)
<
M aterial:
Copper-free alum inum
<
Certification:
CSA certified with the NRTL/C qualifier (certified to Canadian and US standards) for
hazardous locations, Class 1, Division 1, Groups B, C, and D.
<
W arranty:
3 years on controllers
<
System Sensitivity:
Sensitivity for the standard controller is field-adjustable over a range of 50 through 80
counts per second (cps) in increm ents of 2 cps. The m axim um response distance is
achieved at a 50 cps sensitivity setting and the m inim um at 80 cps. For applications
involving high background radiation potential, the system can be desensitized by
increasing the count rate required to actuate it.
<
Response Tim e:
Response to a saturating (high intensity) IR source is typically 10 m illiseconds for the
instant alarm outputs and 0.5 seconds for the area alarm outputs when sensitivity is set
for 50 cps and tim e delay is set for 0.5 seconds (m inim um settings).
