Visonic PG2+ PowerMaster SMD-976 Wireless Smoke & Heat Detector (VIS-0-500421)

The SMD-976 PGP is a dual-sensor wireless smoke and heat detector built to deliver reliable fire detection with modern PowerG+ radio technology. It combines optical smoke detection with a fixed temperature or rate-of-rise heat sensor to catch both smouldering and fast flaming fires in one unit. It features internal piezoelectric sounder capability, and is designed for use in residential, commercial and monitored security systems.

The device supports advanced reporting features for maintenance and diagnostics. It includes battery level reporting so installers and users can monitor remaining battery voltage. It also reports chamber dust levels to compatible panels, helping maintenance teams know when cleaning is needed. The detector is dealer lockable to prevent unauthorised tampering or reprogramming.

Under typical use, the unit can offer up to six years of battery life. The chamber has been repositioned at the top of the detector for easier access and cleaning, making routine upkeep less intrusive. It also incorporates enrolment via two-factor authentication for higher security in the setup process.
