The ALARM RELAY connector consists of a DB-15 female connector. This connector
provides access to two alarm relays within the unit. These relays can be connected to
remote alarms or monitoring devices to report the status of the Stinger MRT.
The ALARM RELAY connector also provides access to four status relays within the
unit that have the ability to monitor the alarm status of up to four remote devices.
Table C-2 shows the pins of the ALARM RELAY connector and their function.

Operation or nonoperation of the status relays is detected by the TAOS software,
based on continuity or lack of continuity between the pair of pins to which it is
connected.
The status relay connections apply 3.3Vdc at less than 10mA through the closed
contacts of the remote relay. The cable associated with this connector must consist of
24-gauge-to-28-gauge conductors.
