## Long description

The ABUS RM40 is a wireless photoelectric smoke detector powered by a 9V lithium battery. Designed for residential and commercial indoor use, it senses smoke particles using a photoelectric sensor and triggers an audible alarm to alert occupants. The detector’s compact dimensions (approximately 10.2 cm diameter and 35 mm height) allow discreet ceiling or wall mounting while maintaining broad coverage for early warning of smouldering fires and slow-developing smoke sources.
Advantages
The RM40 uses photoelectric detection technology which is particularly effective at identifying smouldering fires and low-flame combustion that produce larger smoke particles. Battery operation and wireless design simplify installation since no mains wiring is required, allowing flexible placement and easy relocation. The lithium 9V battery provides extended operating life and stable performance over time. The unit’s compact form factor and neutral finish integrate unobtrusively into most interiors.
