1. Introduction
The Merten MEG5522-0019 Argus Sensor Module is a presence detector designed for indoor ceiling mounting. This module detects heat sources within an adjustable detection area, initiating a staircase light timer. It integrates a light sensor with an adjustable brightness threshold, ensuring illumination activates only when ambient light falls below a specific level. The presence function allows the lighting to switch off even when a person is present, provided sufficient natural light is available. When combined with dimmable inserts, the switchable light control feature maintains a nearly constant room illumination by continuously measuring and adjusting room brightness to a set value.

2. Safety Warnings
WARNING:
Electrical work must be performed exclusively by qualified electricians or under their direct supervision and guidance. Improper installation can lead to electrical shock, fire, or other hazards. Always disconnect power at the main circuit breaker before performing any installation or maintenance.
3. Setup and Installation
The sensor module is designed for installation in a standard 60mm flush-mounted box or an accessory surface-mounted housing (sold separately). The recommended mounting height for optimal performance is 2.5 meters.
Installation Steps:
- Power Disconnection: Ensure the main power supply to the installation area is switched off at the circuit breaker.
- Mounting Location: Select a suitable ceiling location, free from obstructions, at the recommended height of 2.5 meters.
- Wiring: Connect the module according to the wiring diagram provided with the product packaging. This step requires professional electrical knowledge.
- Secure Mounting: Install the sensor module securely into the 60mm flush-mounted box or surface-mounted housing.
- Power Restoration: Once installation is complete and verified by a qualified electrician, restore power to the circuit.
4. Operating Instructions
The Merten MEG5522-0019 Argus Sensor Module offers various adjustable functions to customize its operation:
Adjustable Parameters:
- Sensitivity: Continuously adjustable to fine-tune the detection of heat sources.
- Brightness Level: Continuously adjustable from approximately 10 Lux to 1000 Lux. This threshold determines when the lighting will activate based on ambient light.
- Operating Time (Channel 1): Continuously adjustable from approximately 10 seconds to 30 minutes. This sets the duration the light remains on after detection for Channel 1 functions.
- Operating Time (Channel 2): Continuously adjustable from approximately 5 minutes to 2 hours. This sets the duration for Channel 2 functions.
Key Functions:
- Staircase Light Function (Brightness-Dependent): Utilizes an electronic switch or relay mechanism to activate lighting based on detected presence and ambient brightness.
- Dual Channel Operation:
- Channel 1: Brightness-dependent staircase light function.
- Channel 2: Brightness-independent staircase light function. Both channels can operate with electronic switches or relay inserts, offering two speeds.
- Dimmable Functions: When paired with compatible dimmable inserts (e.g., universal dimmer, 1-10V control insert), the module supports brightness-dependent staircase light functions and light adjustment.
- Light Control: Provides brightness-independent staircase light functionality, often used with central control points.
- Presence Function: Allows the system to switch off lighting even if a person is present, provided there is sufficient natural light, optimizing energy consumption.
5. Maintenance
The Merten MEG5522-0019 Argus Sensor Module requires minimal maintenance.
- Cleaning: Gently wipe the surface of the sensor with a soft, dry cloth. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the device.
- Inspection: Periodically check the sensor for any physical damage or loose connections. If any issues are observed, contact a qualified electrician for inspection and repair.
- No User-Serviceable Parts: The device contains no user-serviceable parts. Do not attempt to open or repair the module yourself.
6. Troubleshooting
If you encounter issues with your Merten MEG5522-0019 Argus Sensor Module, consider the following:
- No Detection:
- Check the sensitivity setting; it might be too low.
- Ensure the detection area is clear of obstructions.
- Verify the mounting height is within the recommended range (2.5m) for optimal coverage.
- Light Not Switching On:
- Check the brightness level setting; if the ambient light is above the set threshold, the light will not activate.
- Confirm power supply to the module and connected lighting.
- Verify the operating time setting for the relevant channel.
- Light Stays On/Off Incorrectly:
- Adjust the operating time settings.
- Review the presence function settings if the light is turning off despite presence.
- Ensure no constant heat sources are within the detection area that could trigger continuous detection.
- All Other Issues: For persistent problems or complex electrical issues, contact a qualified electrician or the manufacturer's support.
