Automated Logic ZN551 User Manual

Module Clock
Clock Fail Date and Time
Date and time control program uses when module's real-
time clock is invalid.
TIP Use an occupied date and time (such as a Tuesday
at 10 a.m.) so the equipment does not operate in
unoccupied mode if the module loses power during
occupancy.
Time Synch Sensitivity
(seconds)
On a Time Synch signal, update the module clock only if
the module time differs from the signal time by more
than this value.

• BACnet device object properties for the ZN551

will handle Life Safety alarms or if you need to send certain types of alarms
only to an alarm manager other than WebCTRL.

priorities for Alarms and Events.
