Smoke detector Digitus DN-S-S wired optical smoke alarm, mains-powered compatible with wired systems

Wired smoke detector Digitus DN-S-S is an optical (photoelectric) smoke alarm intended for permanent installation in hardwired fire detection systems. The device senses visible combustion particles using a photoelectric sensing chamber and provides an alarm output compatible with standard building alarm panels and wired system architectures. It is mains-powered and designed for indoor use in residential, commercial and light-industrial environments where a reliable, continuously powered smoke detection point is required.

Advantages

The optical detection principle offers reliable early warning for smoldering fires and slow-developing smoke events while reducing false alarms from short-lived combustion sources. Being mains-powered and designed for wired system connectivity ensures continuous operation without dependence on local batteries and allows central alarm management and monitoring. The unit’s fixed installation and standardized alarm output simplify integration into existing wired fire detection systems and building control panels.

Suitable for

• Permanent smoke detection in residential apartments and houses
• Alarm integration in commercial premises such as offices, retail and hospitality
• Light-industrial indoor areas where wired fire detection is required
• Replacement or expansion of existing mains-powered, wired alarm systems

Key specifications

• Detection principle: optical (photoelectric) smoke sensing
• Power source: mains-powered for continuous operation
• Output: alarm output compatible with wired building alarm panels
• Installation: fixed ceiling or wall mount for indoor use
• Intended environment: residential, commercial and light-industrial indoor applications

How to use

Install the detector in accordance with local fire safety regulations and wiring standards, selecting ceiling or high-wall locations for optimal smoke access. Connect the unit to the building’s wired fire detection loop or compatible alarm panel, ensuring correct wiring for power and alarm output. After installation, perform system commissioning and functional tests to verify detection and communication with the central alarm system. Regularly inspect and test the detector as part of the building’s maintenance schedule to confirm continued operation.

Usage recommendations

Place detectors in circulation areas, living rooms and corridors away from direct cooking fumes or steam sources to reduce nuisance alarms. Follow manufacturer and local code guidance for spacing, mounting height and interconnection when integrating multiple devices into a wired detection network.
