The Ajax Keypad Plus works with the Ajax hub+, hub2 & hub2+ to allow keyed entry on top of any SpaceControl or app use.
the plus model works with contactless access devices
The Keypad also has an indication of current security status, problems with detectors or breakdown of communication with the hub.
With KeyPad Plus, it is no longer necessary to create an Ajax account for new users. Just provide a person with an RFID tag or card to grant them access to the whole security system or particular groups. A smartphone with Ajax app and Bluetooth enabled works as an access device.
