Jablotron JA-111ST-A

Jablotron JA‑111ST‑A Smoke & Heat Combined Detector

The Jablotron JA‑111ST‑A is a combined smoke and heat detector designed for fire safety in homes and commercial spaces. It features an optical smoke sensor together with a heat sensor, allowing it to detect both smoke and rapid temperature increases. The unit works with Jablotron BUS alarm systems (100/100+) and can operate on batteries if system power is lost. It provides clear visual and audible alarms to warn of fire hazards.

Features

• Combined detection: Optical smoke sensor + heat sensor in one unit.
• Optical smoke sensing: Detects dense smoke using light scattering technology.
• Heat detection: Class A1 heat sensor responds to rapid temperature rises.
• Battery support: Can operate on 3 × AA batteries if system power fails.
• Visual & acoustic alarms: Built-in siren and LED indicators provide clear warning.
• System integration: Works as part of Jablotron BUS alarm systems.

Benefits

• Simultaneous smoke and heat detection increases fire hazard sensitivity.
• Battery operation ensures continued protection during power outages.
• Simple installation in residential and commercial settings.
• Fully compatible with Jablotron 100/100+ alarm systems for integrated safety.

Package Contents: JA‑111ST‑A detector, mounting bracket, screws, and user documentation.
