You will be able to distinguish between the products by presenting the transponder to the devices. If the device responds, it is of the same type and frequency.
Please see the Guard manual section titled 'Changing batteries'. The manual is available online from this product's Documentation page in the Support section of the website.
Normally a device will detect a battery change automatically. If this is not the case, use a "Change of Battery" indicator card. This card will reset the corresponding battery parameter in the cylinder and will be documented as an event. In principle, a battery change card has to be authorised on a device in the same way as a normal transponder authorisation.
You can update in the app directly from your smartphone.
Stay within range of the device, tap 'Lock List' and select the lock. Then click the hamburger menu (three vertical dots) in the top right corner and select 'Maintain Lock'. The app will check the current firmware and compare it with the latest available version. If the version is not up to date, tap on the lock to update it and follow the instructions in the app.
See our "Manual of Signalisation" guide.
There is no exact minimum distance. It depends on the performance of the smartphone and the physical environment around the door.
