Honeywell EC350 - 7.2.1.8 Forcing a Test Call; 7.2.2 Call out; 7.2.2.1 Set Call Out time

7.2.1.8 Forcing a Test Call
During initial commissioning as well as subsequent troubleshooting, it is useful to be able to manually
evoke a call. This can be done by writing the proper value to item 264: 20139796 will trigger a scheduled
call; 20139813 will force an alarm call. The same can be done using the HMI. See the HMI section for
details.
7.2.2 Call out
The Call Out window (COW) allows EC350 to accept remote communications during one or two blocks of
time during the day.
When used with a CNI2 cellular modem, the CNI2 will be set to “server mode” during the call out window
(s) so it can accept calls from a host system during those times. The CNI2 consumes more power in server
mode, regardless of whether communication occurs.
EC350 can also be kept “awake” during the call out window(s) such that even the initial characters of a
communication session are accepted. Otherwise, the initial characters “wake up” the EC350. The MI
Protocol includes such wake up characters in its protocol so that this feature is not required for MI
Protocol communication. But the Modbus protocol includes no wake-up characters, so this feature can be
used so that the EC350 processes the first Modbus packet. Without it, the first packet is not processed
and the Modbus host system must send a “retry” packet. More power is consumed during the call out
window in this mode, regardless of whether communication occurs or not. To use this mode, in addition to
specifying a call out window, set item 1236 (Port Active During COW) to enabled. This mode consumes
more battery power but reduces retries on Modbus activity.
There are items for specifying the start and stop times for two call out windows. Set the start and stop
times equal to disable a call out window. (Do so for both if they have no call out window.) Times are
specified in 24-hour format. The maximum value is “23 59 00”. Seconds other than “00” are ignored. The
resolution for the times is one minute. No single call out window can be longer than 18 hours, but greater
than 18 hours can be achieved by scheduling two call out windows “back to back” (e.g. 00 00 00 - 12 00
00, 12 00 00 - 23 59 00 would effectively give you a call out window for the entire day except one minute
before midnight).
The modem will stay active until a stop time is reached or when the current call (if after the stop time) has
ended. EC350 goes back to sleep if there is no call out.
