Ajax SpeakerPhone Jeweller (87531.180.BL1) is a wireless voice module for alarm verification and two‑way audio communication between a monitored site and a central monitoring station (CMS). Using Ajax’s secure Jeweller signalling and VoRF audio streaming, the unit provides full‑duplex voice, AI‑assisted microphone processing for noise suppression, and remote configuration via Ajax apps. It supports pre‑installed batteries with optional 12 V external power and is designed for simple SmartBracket mounting.
