Smoke Detector ABUS RWM450

The ABUS RWM450 is an optical smoke detector designed for wireless, interconnectable domestic smoke detection. It uses an optical sensing chamber to detect visible combustion particles and is powered by a 3V lithium battery. With a compact 10.5 cm diameter and 40 mm height, this ceiling- or wall-mountable unit meets the EN14604:2005/AC:2008 standard for smoke alarm performance and reliability.

Advantages

The detector provides optical smoke sensing for early warning of smouldering fires and visible smoke, and supports wireless interconnection to expand protection across multiple rooms without running cabling. Battery power allows flexible placement where mains supply is not available, while the compact form factor simplifies installation on ceilings or walls. Certification to the EN14604 standard confirms compliance with recognised test criteria for sensitivity, false alarm resistance, and alarm output.

Suitable for

• Residential rooms such as bedrooms, living rooms and hallways
• Small apartments and single-family houses where wireless interconnection is preferred
• Retrofit installations where cabling is impractical or costly
• Locations requiring a compact, battery-powered optical smoke alarm

Key specifications

• Detection principle: optical (photoelectric) smoke sensor
• Power source: single 3V lithium battery
• Form factor: circular housing, diameter 10.5 cm, height 40 mm
• Connectivity: wireless interconnect capability for multi-unit alarm signalling
• Standards: tested and certified to EN14604:2005/AC:2008

How to use

Mount the ABUS RWM450 on a ceiling or high on a wall according to the manufacturer’s placement guidelines for optimal smoke detection. Insert the 3V lithium battery and follow the pairing procedure to interconnect multiple units if distributed protection is required. Test the detector after installation using the built-in test function to verify correct operation and check the alarm sound and interconnect signalling. Replace the battery promptly when the low-battery indicator activates and clean the sensor housing periodically to prevent dust accumulation that could affect sensitivity.

Usage recommendations

Install one detector in each sleeping area and on every level of the dwelling, avoid placing the unit too close to kitchens or bathrooms where cooking smoke or steam could cause nuisance alarms, and follow local building codes and the EN14604 guidance for detector spacing and mounting height. Regularly test the unit and replace batteries as recommended to ensure continuous protection.
