The remote wall plates provide the same functionality as the buttons on the front of the A 4595. All switches have safety covers to prevent accidental triggering. If a tone is triggered by the main unit or a paging console the corresponding switch on the wall plate will illuminate. Connection is made via Cat5e cable with a maximum range of 300m and up to 16 wall plates can be cascaded together. Each wall plate must have its own ID number which is set by DIP Switches on the rear of the plate.
