SKU:
AJ-42808

An indoor siren adjustable from 80 to 100 dB at 3.3 feet, with a 6,500 foot radio range that reaches across almost any residential or small commercial site from the hub.

Built for the installer

Adjustable volume is more useful than it sounds. The same part covers a hallway in a flat where 100 dB is antisocial and a warehouse where it is barely audible, set in the app rather than by a DIP switch behind the cover. Default is 93 dB.

Alarm duration is configurable from 3 seconds to 3 minutes, which matters where local noise ordinances cap how long a siren may sound. It runs up to five years on two pre-installed CR123A cells and is classified a type W internal, self-powered warning device.

How loud is it and can that be changed?
Adjustable from 80 to 100 dB at 3.3 ft, with a 93 dB default. It is set in the Ajax app rather than by a switch behind the cover, so it can be tuned after installation.
Can the siren duration be limited?
Yes, from 3 seconds to 3 minutes. That matters where local noise ordinances cap how long an audible alarm may sound.
Does the siren need mains power?
No. It is a type W internal, self-powered warning device running on two pre-installed CR123A cells for up to 5 years, so it can be sited for effect rather than near a socket.
Does this device need an Ajax hub?
Yes. All Jeweller devices report to an Ajax hub or a range extender. The device cannot operate standalone and does not connect to a third-party panel directly.
What does the 9NA region code mean?
It is the North America model, operating on the 905.0-926.5 MHz Jeweller band certified to UL/ULC standards. European models on 868 MHz are not interchangeable with it.
How quickly is a lost device detected?
Within 36 seconds. Jeweller polls each device continuously, so a jammed, removed or failed device is reported rather than quietly going offline.
