Product information

Description

The ABUS RM40 Optical Wireless Smoke Detector is designed to provide reliable fire safety and early warning for residential and commercial environments. Utilizing an optical detection method, this device quickly identifies smoke particles entering the measurement chamber and immediately alerts occupants with a powerful built-in siren. Operating on a wireless frequency of 868 MHz, it allows seamless interconnection of up to 32 compatible devices, ensuring that an alarm triggered in one room is instantly transmitted to all connected units throughout the building. Powered by a dependable 9 V lithium battery and housed in a clean white enclosure, this smoke detector functions as a standalone unit or as part of a comprehensive safety network.

Advantages

The wireless interconnection capability of the ABUS RM40 ensures that all linked detectors sound simultaneously when smoke is detected, significantly improving safety in larger homes or multi-room spaces. Its loud 85 dB alarm provides clear acoustic warning even from a distance. The optical sensor technology reacts quickly to slow smoldering fires while minimizing false alarms. A built-in test button allows for straightforward functional checks, and the battery-powered design eliminates the need for complex wiring during installation.

Suitable for

  • Residential houses and apartments requiring interconnected fire protection
  • Multi-room commercial spaces and offices
  • Bedrooms, hallways, and living areas needing early smoke detection
  • Properties where wireless expansion up to 32 detectors is necessary

This smoke detector may not be suitable for outdoor environments, areas with high humidity or excessive dust, or spaces where smart home integration via virtual assistants or smartphone apps is required, as it operates as a standalone wireless radio-frequency system without smart platform connectivity.

Key specifications

  • Detector type: Optical smoke detector
  • Connectivity technology: Wireless radio frequency
  • Frequency bandwidth: 868 MHz
  • Maximum connected devices: Up to 32 units
  • Alarm volume: 85 dB
  • Power source: 9 V lithium battery
  • Dimensions: 10.2 cm diameter and 35 mm height
  • Product color: White

To use the ABUS RM40, securely mount the unit to the ceiling in the desired location using appropriate hardware. Ensure the 9 V lithium battery is properly inserted into the compartment. Test the device regularly by pressing the integrated test button to verify that the internal piezo alarm sounds correctly. If multiple devices are used, follow the pairing instructions to network them together on the 868 MHz frequency band so that signals transmit across all units.

What to consider before purchase

  • Verify that the wireless frequency and interconnection limit of 32 devices meet your property requirements
  • Check that the environment is free from excessive dust, steam, or high moisture that could interfere with optical sensors
  • Confirm that smart home app integration is not required, as this model operates independently of internet-connected platforms
  • Ensure regular battery replacement and testing schedules can be maintained

For optimal safety, test the smoke detector regularly using the integrated test button and replace the 9 V lithium battery promptly when a low voltage indication is given by the LED indicator.
