4. Setup and Installation
The RK150DTG300B is designed for ceiling mounting to provide optimal 360° detection coverage.
4.1. Site Selection
- Choose a central location on the ceiling within the area to be protected.
- Avoid mounting near heat sources, air conditioning vents, or areas with significant air drafts that could cause false alarms.
- Ensure the detection area is clear of large obstructions.
4.2. Mounting the Detector
- Carefully separate the detector's base from its cover.
- Position the base on the chosen ceiling location and mark the drilling points.
- Drill holes and insert appropriate anchors if necessary.
- Secure the detector base to the ceiling using the provided screws.

4.3. Wiring
The RK150DTG300B is powered by an electrical cable. Connect the detector to your security system's control panel according to the panel's instructions and the detector's terminal markings.
- Power Connection: Connect the power supply wires to the designated terminals.
- Alarm Output: Connect the alarm output to the appropriate zone input on your control panel.
- Tamper Output: Connect the tamper output to a 24-hour tamper zone on your control panel. The detector features anti-removal and anti-opening tamper protection.
- EOL Resistors: Integrated End-Of-Line (EOL) resistors are selectable via jumpers. Refer to your control panel's manual for the required EOL resistor values and configure the detector accordingly.
4.4. Configuration and Testing
- Anti-Cloak Technology (ACT): This feature enhances detection capabilities by identifying attempts to mask the infrared signal.
- Green Line Feature: Allows for the deactivation of the microwave (MW) channel when the security system is disarmed, reducing power consumption and potential interference. This is typically configured during installation.
- Walk Test: After installation, perform a walk test to verify the detector's coverage and sensitivity. Walk through the entire protected area to ensure the detector triggers an alarm. Adjust sensitivity if necessary (refer to specific jumper settings or potentiometers if available on the device, though not explicitly detailed in product description).
5. Operating the Detector
The RISCO RK150DTG300B operates automatically once properly installed and powered. It continuously monitors the protected area using its dual technology sensors.
- Dual Technology: The detector combines Passive Infrared (PIR) and Microwave (MW) detection. Both technologies must typically be triggered simultaneously to generate an alarm, significantly reducing false alarms.
- 360° Coverage: The ceiling mount design provides a full 360-degree detection pattern, covering an area up to 13 meters in diameter.
- Tamper Protection: The integrated anti-removal and anti-opening tamper switches will trigger an alarm if the detector is tampered with or forcibly removed from its mounting location.
6. Maintenance
To ensure the long-term reliability and performance of your detector, follow these maintenance guidelines:
- Cleaning: Periodically clean the detector's lens and housing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Regular Testing: Perform a walk test at least once a year, or as recommended by your security system provider, to confirm proper operation.
- Inspection: Visually inspect the detector for any signs of damage or loose connections.
7. Troubleshooting
If you experience issues with your RK150DTG300B detector, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| False Alarms | Heat sources, air drafts, small animals, improper sensitivity settings. | Relocate detector, eliminate drafts, adjust sensitivity (if applicable), ensure proper mounting. |
| No Detection | Power loss, incorrect wiring, obstructed view, detector malfunction. | Check power supply, verify wiring, clear obstructions, perform walk test. If problem persists, contact support. |
| Tamper Alarm | Detector cover open, unit removed from mounting, loose connections. | Ensure cover is securely closed, unit is firmly mounted, check tamper wiring. |
If troubleshooting steps do not resolve the issue, contact your security system installer or RISCO technical support.
