3. While supporting the P-BK-MON-G card, remove the screws that hold the
P-BK-MON-G card on its mounting pillars. Store the screws in a safe place for reuse.
4. Remove the P-BK-MON-G card from its mounting pillars.
6.3.2 Installing and Configuring the Beacon Monitored Card (P-BK-MON-G)
The Beacon Monitored card is a panel mount card assembly that is mounted on the Power
I/O panel in the lower part of the front access cabinet. After installation, the Beacon
Monitored card must have its I/O Bus address set. See the PAGASYS GEN II Beacon
Monitored Technical Installation Guide for more information on configuring the I/O Bus
address.
The P-BK-MON-G module assembly contains two cards separated by spacers, and a
metal shield and connected by two cable looms. The lower card provides the Beacon
Circuit Field Terminal blocks and relay switching circuitry for two independent beacon
circuits. The upper card provides an on-board microprocessor, which coordinates the
operation of the card, including the relays mounted on the lower card.
To install and configure the Beacon Monitored card (P-BK-MON-G):
1. Before removing or installing the P-BK-MON-G card, ensure that all AC and DC
power supplies serving the cabinet are turned off and isolated.
2. Place the P-BK-MON-G card on to its housing mounting pillars and fasten to the
pillars using the screws supplied or previously removed.
3. Referencing the cabinet wiring drawings and the Technical Installation Guide,
connect the P-BK-MON-G card connectors to the system cables in the following
manner:
• Connect the Beacon circuit 1 AC Load Out wires from the bottom card terminal
block TB3.
