How do I change the batteries on my Apartment alarm?
Disable the siren tamper via the Key Pad, as per diagram below.
Press button A on the keypad and insert your pincode.
Then press button A again, followed by the number 2 – that disables the siren tamper.
Then you have 1 hour to change the batteries. You cannot arm or disarm it during this hour unless you turn the tamper back on. To do so you press button A then the pincode.
Then button A followed by number 3.
Then press disarm twice.
