Ajax StreetSiren Jeweller is a wireless siren for outdoor and indoor use. On alarm it sounds at 85–113 dB measured at one metre, and the bright LED frame draws attention to the site from a distance. Volume and alarm duration (from 3 seconds to 3 minutes) are adjustable from the Ajax app.
The siren also shows the state of the system: the security mode, entry and exit delays and after-alarm indication, which helps a patrol find quickly which site raised the alarm. The chime function signals a door opening while the system is disarmed.
The enclosure is rated IP54, and tamper protection together with the holding screw reports any attempt to open the siren or detach it from the wall. Communication with a hub or range extender runs over Jeweller radio at a range of up to 1,500 m, encrypted and frequency-hopping. The pre-installed 4 × CR123A batteries last up to 5 years.
