The WSD-1 is a wireless, addressable photoelectric (optical) smoke detector for the FireSmart wireless fire alarm system. It detects smoke from smouldering fires early and communicates with the WCP-1 control panel over a self-routing 444.4 MHz radio mesh, so no signal cabling is required.
Key features
- Wireless and fully addressable
- Photoelectric (optical) smoke sensing
- Battery powered with LED and audible low-battery warning
- Self-routing radio mesh at 444.4 MHz

Network capacity and operation
The WSD-1 operates as part of a WCP-1 wireless control panel network, which supports up to 160 addressable devices per network using self-routing mesh communication, so each device also helps relay signals for others further from the panel — useful in larger or multi-floor buildings. The network is programmed directly from the WCP-1 panel using its built-in USB keypad, without separate wireless programming software. For day-to-day operation and maintenance checks, see our guide to operating an addressable wireless fire alarm system, and for detector placement, smoke detector spacing per NFPA 72.
Standards: designed to meet TCVN 7568-14:2025 (based on ISO 7240), the Vietnamese standard for the design and installation of fire alarm systems.
