Customer Question

I have a DSC PC1500/1550 alarm system and need a new battery. My question is can I use the system without the battery. If I want to replace the battery, what buttons on the keypad do I push to enable me to open the box without setting off the alarm?
Thank you for your help.

Hi there,

You cannot use this alarm system without a backup battery.

To open the box without setting off the alarm, you can put it in service mode, or simply turn off the power supply since the battery is dead/dying.

Please explain?
