8. ALARM DELAY: This parameter allows for a delay in response to the alarm. The recom-
mended setting is between 5 & 30 seconds. An alarm condition must be continuously present
for the duration of a full delay time before the GA-170 will change to the ALARM state. NOTE:
Increasing the delay time may help to avoid false alarms caused by transient effects.

9. ALARM TYPE: The high alarm for each channel can be set to latching or non-latching.
Selection is changed using the

alarm) condition. If an alarm state is reached while in the latching mode the user must still
acknowledge the alarm by pressing the
key after the alarm condition has already been
alleviated in order for the red LED and relay to be de-activated.
NOTE: Latch:1 = Latching, Latch:0 = Non-latching, Fsafe:1 = Failsafe, Fsafe:0 = Non-failsafe.
