alarms to add to those automatically created as you configure the controller. This is a
powerful feature of the SC 255 with great flexibility. Every relay output and sensor
will be listed in the miscellaneous alarm screens. Alarms can be configured here to be
active on only specified days, too. You can also create multiple alarms for the same
relay or sensor, with different time delays and action levels.
After you select Miscellaneous from the main Alarm Configuration Menu, you will
see the first page of the first of five miscellaneous alarm list screens. It lists all the
relay outputs in the system. The Alarm Configuration Menu and the Misc Alarms -
Relay Output list screen are shown below:
Before we go on to discuss configuring miscellaneous alarms for relay outputs,
observe the icons at the bottom of the screen above right. The first icon represents
relay outputs, the current screen. The others, from left to right, are in reverse video
(unselected) and represent analog inputs, digital inputs, analog outputs, and casc
controllers respectively. Selecting any one of these icons will take you directly to that
area of configuration.
For each point selected, whether an output or input, up to 3 different alarm satements
can be used, and each can be active on a time schedule. As an example, a meat prep
room may be occupied only during certain hours; therefore, different alarm levels
might be useful. An example follows for such a prep room controlled by an AKC 164
Smart Case Controller. The principles discussed here can also be applied to digital
outputs, analog inputs, or any other kind of input or output.
Example
Misc. alarm. In this example, the meat prep room is controlled by a Smart Case Controller. To find
the temperature sensor, we must select the case controller icon once we have arrived
at the first miscellaneous alarms screen shown at right above. The screen might
appear as at left below.
