Description
Ajax 42794.26.WH3 Button (9NA) UPC white
Product Details
Button Jeweller is a wireless panic button that also works as a smart button. It runs in three modes: panic, control of automation devices, or muting a fire alarm — so the same hardware is a hold-up button behind a counter or a one-press light switch, depending on how it is configured.
The alarm type is selectable from intrusion, fire, auxiliary alarm, panic button, gas alarm, malfunction, leakage and custom. An adjustable-brightness LED confirms the press. The pre-installed CR2032 battery lasts up to 5 years, with a daily automatic battery check that needs no button press, and Jeweller radio reaches 1,000 ft in open space.
Accidental-press protection requires a long or double press. The IP55 enclosure resists dust and splashes, and the button can be carried loose or fixed in place with the Holder accessory, sold separately. Supplied in the white finish. The same device in black is stocked as 42793.26.BL3.
