8-9.4.2.3 Using EDIT MENU option 2 to activate/deactivate switches
NOTE
Switches are activated/deactivated for the same reason and in a similar manner to
activating/deactivating sensors in paragraph 8-9.4.2.1. Deactivating a switch stops
main processor from monitoring that particular switch. Deactivation may be
necessary when a switch is malfunctioning, is displaying false information on
video monitor display page and is activating alarms when no problem exists.

switch emblem on video monitor display page. After switch is repaired or
replaced, switch is reactivated. The word DEACTIVATED disappears and switch
emblem again appears on video monitor.
