SpaceControl Jeweller Wireless Key Fob with Panic Button, Black

SKU AJ-42842

  • Fast shipping from four branches
  • 30-day returns on unopened products

A four-button key fob for arming, disarming, night mode and panic. It assigns to a specific user, so the event log shows who armed the system rather than just that it was armed.

Built for the installer

User assignment is the detail that matters commercially. On a site with staff coming and going, a fob tied to a named person turns the event log into an audit trail. A fob can also be scoped to a specific security group, so a key holder only controls their own area.

Accidental press protection requires a long or double press, which is what keeps it from arming in a pocket. Rated -13F to 122F and IK04 impact rated, on a CR2032 that runs up to five years.

FAQs

Can a fob be tied to a specific person?
Yes. Each fob is assigned to a user in the Ajax app, so the event log records who armed or disarmed the system rather than only that it happened.
Can a fob control only part of the system?
Yes. A fob can be assigned to a specific security group, so a key holder controls their own area without being able to disarm the rest of the site.
Will it arm accidentally in a pocket?
Accidental press protection requires a long press or a double press, which prevents activation from incidental pressure.
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.
