3.3.1.2 Dry Contacts
The dry contacts terminal connectors (see Figure 3-2) are located on the rear panel of the
alarm display unit. The four contacts on the input terminal block correspond to Critical,
Major, Minor, and Audio Shut-off alarm inputs. The output terminal block contacts
correspond to Critical, Major, Minor, and Audio Shut-off alarm outputs. These terminal
blocks can be used to connect remote alarm indicators. When an alarm condition occurs, the
corresponding relay is closed to connect a voltage on the input terminal to a remote alarming
device on the output terminal. See Table 3-1 for the dry contact relay functional specification.
Additionally, an audible alarm can be remotely disabled by connecting to the Shut-off Alarm
contacts. Refer to Appendix A for the dry contact electrical specifications.
