Alarm System
There are two Trinix alarm classes: primary and secondary. A sec-
ondary alarm is asserted when a single fan has failed or when the sec-
ondary NR/SR Broadlinx board has taken control of the system. All
other alarms (multiple fan failure, power supply failure, etc.) are con-
sidered primary alarms.
All major components include a local alarm LED. NR/SR-33000 boards
have separate LEDs for primary and secondary alarms.
The master alarm indicator is a tri-color LED on the front panel
(“Power/Alarm”) where green indicates normal operation, red indi-
cates a primary alarm, and amber indicates a secondary alarm.
The rear panel “Alarm” BNC can be configured to report primary
alarms only or both primary and secondary alarms. The factory default
configuration is to report both. (DV-33128 and DV-33256 configuration
is via a jumper on the NR/SR-33000 board, as shown on page 119 and
page 120. DV-33512 configuration is via a jumper on the RP-33500 512
x 512 Rear Panel board as shown on page 122.)
Electrically, the Alarm BNC operates according to SMPTE standard
269M-1999. When an alarm is asserted, the circuit associated with the
Alarm connector will present a low impedance to an external current
source circuit provided by the customer. See Figure 12.
