Contact Closure Sensors
On models with the contact closure sensor feature (see Table 1), the chassis
provides an optional 8-pin connector (4 contact sensors) on the back of the
chassis that can be used to sense the state of external alarm conditions. Each
of the four sensor pins can detect if the wired circuit is open or closed, or has
high or low voltage from the external equipment. A DIP-switch located on the
back of the chassis enables or disables alarm reporting. If no external equipment
is connected to the 8-pin connector, it is important to disable the alarm reporting
by configuring each DIP-switch to the DISABLE position. See Figure 5 for the
location of the switch and terminal connector.
