display.

< One or two 4-20mA current outputs to send important system information to other devices

DESCRIPTION

The IRC90H fire detectors and UxF-IR fire controllers provide fast, reliable flame detection in a wide

variety of applications. The microprocessor 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 Automatic Visual

Integrity (vi) feature, which provides a continuous check of detector optical surfaces, detector sensitivity,

and electronic circuitry of the detector/controller system. Automatic fault identification monitors the system

for proper operation and provides a digital display of system status using a numerical code. Controller

response includes actuation of three or four relays for direct control of field response devices, one or two 4

to 20mA current outputs, a full array of faceplate indicators.

CONTROLLER SPECIFICATIONS

< Operating Voltage:

24 Volts DC. Device can operate between 18 and 32 Volts DC

< Power Consumption (controller only):

2.4 watts nominal, 4.4 watts maximum

100 mA nominal, 180 mA maximum at 24 Volts DC

Maximum start-up current is 1.5 Amperes for 10 milliseconds. Power supplies with fold

back current limiting are not recommended

< Maximum Ripple:

Ripple should not exceed 5 Volts peak-to-peak. The sum of DC plus ripple must 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 Normally open/normally closed contacts rated for 5 Amperes at 30 Volts DC/ 250

Volts AC

< Current Outputs:

One or two 4-20mA DC current, with a maximum external loop resistance of 600 Ohms at

18-32 Volts DC

< Dimensions:

Refer to Figures 1 and 2

Figure 1 - UxF-IR Dimensions in Inches (Side

View)

< Shipping Weight (approximate):

6 lbs (2.7 kg)

< Material:

Copper-free aluminum

< 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.

< Warranty:

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 maximum response distance is

achieved at a 50 cps sensitivity setting and the minimum 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 Time:

Response to a saturating (high intensity) IR source is typically 10 milliseconds for the

instant alarm outputs and 0.5 seconds for the area alarm outputs when sensitivity is set

for 50 cps and time delay is set for 0.5 seconds (minimum settings).

< Terminal Configuration:

See Figure 3 for U4F-IR terminal configuration

For U2F-IR controllers SENSOR INPUT 3, SENSOR INPUT 4, VI DRIVER 3, and VI DRIVER 4

terminals are not used.

For U1F-IR controllers SENSOR INPUT 2, SENSOR INPUT 3, SENSOR INPUT 4, VI DRIVER 2,

VI DRIVER 3, VI DRIVER 4, AREA 2 CURRENT OUTPUT, and AREA 2 TIMED ALARM RELAY

terminals are not used.
