The JA-110A II is a BUS‑connected indoor siren designed for use within JABLOTRON 100+ alarm systems. It sounds alarm tones, indicates system status, notifies entry and exit delays and can trigger programmable outputs (PG) as configured via the control panel software.
Main features: optional LiFePO4 CR2 3.2 V (0.4 Ah) backup battery, built‑in piezo sounder rated at 100 dB/m (±5 dB), tamper switch and a front button that can silence the alarm or be set for panic activation. Button behaviour is configurable in system software.
The device is powered from the control panel BUS (nominal 12 V DC). Respect the documented maximum current consumption (up to 120 mA) when selecting wiring and, if required, fit the recommended backup battery to ensure 24‑hour or autonomous operation.
Technical summary:
