Wiring Keyswitches

Latching or spring loaded keyswitches can be used to set and unset the Galaxy panels; option 52 = PRO-
GRAM ZONES has provision to accommodate both types of transition.
If the keyswitch latches, the transition from 1 kΩ to 2 kΩ initiates the setting procedure of an unset system,
the transition from 2 kΩ to 1 kΩ instantly unsets a set system. If the system is already set, then the transition
from 1 kΩ to 2 kΩ has no effect. If the system is unset, the transition from 2 kΩ to 1 kΩ has no effect. This
is programmed as a Keyswitch in the PROGRAM ZONES option.
If the keyswitch is spring-loaded (returns to its normal position), the transition from 1 kΩ to 2 kΩ initiates the
setting procedure of an unset system and instantly unsets a set system, the transition from 2 kΩ to 1 kΩ - the
return to the normal position - has no effect. This is programmed as a Keyswitch in the PROGRAM
ZONES option.
