6 The Detector monitors Infrared radiation in the 8 to 15 micrometer range and looks for changes in this radiation such as an intruder walking through its 65 degree cone of vision. The IRM90-R comes with a swivel mount to make mounting and angle adjustments fast and easy. The explosion proof housing is factory sealed to further reduce the labour involved with installation. Normally Open Energized fail safe relay contacts allow for connection to alarm circuitry, annunciation panels or other devices. The electronic circuitry does not require any adjustments by the user. Features 3/4 NPT conduits fitting for easy installation.

7 Factory sealed enclosure eliminating the need for conduit seals in the field. Normally Open Energized, fail safe relay contacts for connection to alarm circuitry or other devices. Relay Contacts will close upon power up and open when Motion is detected or power is lost to the Detector . One meter of 16 AWG cable is connected to the sensor for easy installation. Flexible 15 to28 VDC operating voltage. Swivel mount provided to further simplify installation. Check Package Remove all the components from the packaging carefully, check components against the packing list. Inspect all components for obvious damage and broken or loose parts.

8 Notify the carrier and distributor immediately of any damaged or missing parts.

The unit should be wall mounted, using the swivel mount provided. The Detector housing should be angled downward at a 45 degree angle. It should be mounted so that it doesn t detect changes in Infrared from heaters, light sources, windows which receive direct sunlight, or moving machinery.

9 The Fresnel lens attached to the end of the Detector provides a 65 degrees cone of vision. This cone of vision has dead zones (areas where the Detector will not see Motion ), but these are dispersed throughout the field of view. The dead zones should not cause detection problems. It would be very difficult for an intruder to move around within the detectors field of view and not come in contact with active regions. See Figure 2. Figure 2: View of Detection (Active) and Dead Zones MAN-0042 Rev 05 IRM90-R October 2008 7 SECTION 2: Installation and Start Up (cont d) Wiring Warning: Do not open the Motion Detector s housing or junction box in a Hazardous area.

10 One meter of wiring cable has been connected to the Detector and the unit has been sealed. There are five wires connected to the unit. The White wire is designated for power and should be connected to the positive terminal of the power supply. The Black wire is to be connected to the negative of the power supply. The unit operates between 15 and 28 VDC. It is recommended that a 24 VDC power supply be used. The Red and Blue wires are connected to the internal relay contacts with an 18 ohm resistor connected in series. The relay contacts are rated at 24 VDC with maximum current rating of 100mA resistive.
