Chapter 2.0 General system operation
2.5 Important notice
A security system cannot prevent emergencies. It is only intended to alert you and your monitoring
station, if applicable, to an emergency situation. Security systems are generally very reliable, but
they may not work under all conditions and they are not a substitute for prudent security practices or
life and property insurance. Your security system must be installed and serviced by qualified secur-
ity professionals. These professionals can instruct you on the level of protection that has been
provided and on system operations.
2.5.1 Power save mode
When the panel is in Power Save mode, it is saving battery life. The integrated keypad is not t urned
on until there is a specific reason, such as a hand wave in front of the panel, or the start of an entry
delay.
When initiated, the status indicators stay on for 30 seconds before turning off. In this mode, the
panel is still f unctioning, but nothing is visible.
Note: For UL listed installations, the user app and touchscreen keypad functions are not available
in this mode; therefore, you must use the integrated keypad or the wireless keypad to arm or disarm
the system.

English
l
French

You can select the language on the touchscreen keypad or the wireless keypad.
