DRU Antenna Options
3.8 External Alarm System Reporting Requirements
The DHU provides normally open (NO) and normally closed (NC) form C dry alarm relay
contacts for reporting minor and major alarms to an external alarm system. A minor alarm is
defined as a high temperature condition. A major alarm is defined as any fault condition
except high temperature. Connections to the alarm contacts are provided through a screw-type
terminal strip. Category 3 or 5 cable should be used for the alarm wires. If an external alarm
system is not in use, no alarm connections are required.
