Indymes & callboxes can be programmed on site but the phone call boxes have to be reprogrammed through black box (or whoever is doing the phone systems now).
We're starting our Pfresh remod & they've started moving depts around to open up where Pfresh will go. The call boxes were going off all freaky so my GSTL had me read up on programming them as they're moved.
On the red callboxes, there's small toggle switches on the back. You flip the second into the program position, hold the reset button 'til it flashes then enter your code. If the code is 325, hit the #1 button 3x, hit reset, #1 2x, hit reset, then #1 5x followed by reset. It should flash the entire code sequence. Flip the toggle back to the home position & do a test, clearing it afterward.
Indyme boxes, you hold down the reset button 'til the #1 flashes. Same steps as the redbox. If a code is 208 (women's restroom), you'd hit #1 2x, reset 2x (because the middle number is zero), #1 8x, then reset.
