As newer JACE platforms are introduced, hardware-specific properties may be appended to the collection of a station’s PlatformServices properties. Examples are given below.
A JACE-700 (JACE-7 series) controller includes properties for an onboard contact input (CI) intended for use with a nearby normally-closed (N.C.) “tamper switch”.
To see the three properties associated with this CI, double-click the station’s PlatformServices, for the Platform Service Container Plugin view, and scroll down to the bottom. See Figure 28.
Figure 28. Tamper switch properties (for JACE-7 controller) at bottom of PlatformServices properties
The three properties related to this tamper switch CI are as follows:
-
Tamper Switch Enabled
Default is
false. If set totrue, the onboard CI labeled “TMP” is polled once a second for a normally-closed (shorted) input. An open results in a “tamperSwitch” alarm from the default source “SystemService”. -
Tamper Switch OK
Read-only boolean that reflects tamper switch status as good (
true) or bad (false). If the tamper switch is enabled, status istruewhile the “TMP” CI reads a closure (short), elsefalseif the CI is open, which generates an alarm. -
Tamper Switch Alarm Support
Expand to access properties to define how “tamperSwitch” alarms are handled in the station, including alarm class and other
“alarm source info” parameters. Applies if “Tamper Switch Enabled” is true.
