Alarm Cable
The alarm cable is an optional component.
The 3930 supports 16 external alarm inputs. The alarm connector is located
in the center/right section of the 3930 labeled ALARMS. The 15 foot alarm
cable has a high density 26-pin D-sub connector on one end, and bare wires
on the other. These wires are then connected to a wire wrap panel.
Of the 26 pins on the connector, there are 16 alarm sense connections to
detect any combination of switch close or opens and 8 returns. Up to two
alarm sense lines can be connected to each return. The alarm sense lines can
be paired with any return, however, it is recommended that the sensed
switches that are paired come from equipment that is commonly grounded.
The alarm pinout is provided in Table 2-2 on page 2-12.
See “Installing an Alarm Cable (Optional)” on page 2-24 for a procedure.
