Self-lock vs. latching mode
The G022G allows for two different working modes; self-lock control and latching control. Self-lock allows for the
usual function of the relay where a command from the operator or the device to change is needed. If input from an
alarm then the relay will
stay locked on until the command “
EXTRT
” is sent to the device from the operator (this is
also the same for latching mode).
With latching controls the device will return to its normal status after a period of seconds determined by the user.
This is
useful for output devices that don‟t need or want to be on for a long time after they have been turned on. For
example alarm horns which might only need to be on for 12 seconds to alert the user.
