1. Introduction
1.1 Product Overview
The ELKRON IR15 is a digital passive infrared (PIR) volumetric detector designed for indoor security applications. It detects motion by sensing changes in infrared radiation within its detection zone. This device features two selectable sensitivity levels, a maximum detection range of 15 meters, and a 90° opening angle. Its Fresnel lens is configured with 18 beams across 4 planes, including a look-down zone for enhanced coverage.
1.2 Safety Information
- Read all instructions carefully before installation and operation.
- Installation should be performed by qualified personnel in accordance with local electrical codes.
- Disconnect power before performing any wiring or maintenance.
- Do not expose the detector to direct sunlight, extreme temperatures, or high humidity.
- Avoid mounting near heat sources, air conditioning vents, or objects that may cause rapid temperature changes.

- ELKRON IR15 Passive Infrared Detector unit
- Mounting screws and wall plugs
- Instruction Manual (this document)
3. Installation
3.1 Mounting Location
Choose a mounting location that provides optimal coverage of the area to be protected. The detector can be mounted on a wall or in a corner. Ensure the detector is positioned to avoid direct line of sight to windows, heat sources, or moving objects that are not intended to trigger the alarm.
Recommended mounting height: 2.1 to 2.4 meters (7 to 8 feet) from the floor.
3.2 Mounting the Detector
- Carefully open the detector casing.
- Mark the drilling points on the wall or corner using the detector's base as a template.
- Drill holes and insert wall plugs if necessary.
- Secure the detector base to the wall or corner using the provided screws.
- Route the wiring through the designated opening in the base.

3.3 Wiring Connections
The ELKRON IR15 requires a 12V DC power supply. Connect the power and alarm output wires to your security system control panel as follows:
- Power Input: Connect 12V DC to the designated terminals (typically + and -).
- Alarm Output: Connect the opto-relay output (NO/NC) to the alarm zone input of your control panel.
- Tamper Switch: Connect the tamper output to a 24-hour tamper zone on your control panel. This switch activates if the detector casing is opened.
Ensure all connections are secure and correctly polarized. Refer to your security system's manual for specific wiring diagrams.
4. Setup
4.1 Sensitivity Adjustment
The ELKRON IR15 offers two selectable sensitivity levels to adapt to different environments and reduce false alarms. A jumper or switch inside the detector typically controls this setting.
- High Sensitivity: Recommended for environments with minimal environmental disturbances.
- Low Sensitivity: Recommended for environments prone to minor disturbances (e.g., small pets, air currents) to prevent false alarms.
After adjusting the sensitivity, perform a walk test to ensure proper detection coverage and to verify that the chosen sensitivity level is appropriate for the protected area.
5. Operating Principles
The ELKRON IR15 is a passive infrared detector, meaning it does not emit any energy. Instead, it detects changes in infrared energy (heat) within its field of view. When a person or object with a different temperature than the ambient environment moves into the detection zone, the detector's Fresnel lens focuses this change onto its pyroelectric sensor. If the change in infrared energy meets the detector's criteria (based on sensitivity settings), it triggers an alarm signal to the connected security control panel.
The 90° detection angle and 15-meter range ensure comprehensive coverage for typical indoor spaces. The "look down zone" feature helps detect intruders moving directly below the detector.
6. Maintenance
To ensure optimal performance and longevity of your ELKRON IR15 detector, follow these maintenance guidelines:
- Regular Cleaning: Periodically clean the detector's lens and casing with a soft, dry cloth to remove dust and debris. Do not use abrasive cleaners or solvents.
- Walk Test: Perform a walk test at least once a year, or after any significant changes to the protected area, to confirm proper operation and detection coverage.
- Power Supply Check: Ensure the 12V DC power supply is stable and within the specified voltage range.
- Environmental Check: Verify that no new obstructions or heat sources have been introduced into the detection zone that could interfere with operation.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector not triggering | No power; incorrect wiring; sensitivity too low; obstruction in detection zone; faulty unit. | Check power supply and connections. Adjust sensitivity. Remove obstructions. Perform walk test. If problem persists, contact support. |
| False alarms | Sensitivity too high; heat sources (heaters, direct sunlight); air currents (AC vents); small pets; vibrations. | Adjust sensitivity to a lower setting. Relocate detector away from heat sources or air vents. Ensure pets cannot enter the detection zone. Check for stable mounting. |
| Tamper alarm active | Detector casing not properly closed; tamper switch faulty; wiring issue. | Ensure the detector casing is securely closed. Check tamper switch wiring. If faulty, contact support. |
