Page 5: Introduction
A N U A L Introduction The 4200 Alarm Circuit Unit (ACU) plug-in card for the 4200 Cable Management System provides armor, copper pair or tracewire monitoring to an outside plant cable network along with sensor monitoring of splice enclosure, remote cabinet and building locations. The ACU can monitor up to 78 miles or 125 kilometers of cable armor/copper conductor and 799 sensor devices. -
Page 6: Theory Of Operation
• Multiplexed Remote Sensors (remote cabinet/building) Norscan Cable Management Systems The 4200 ACU card is capable of providing cable, splice enclosure, end to end continuity and remote cabinet/building monitoring when installed in the 4200 CMS chassis. The ACU card will monitor the metallic conductor for faults to ground, end to end connectivity and sensor activation activity to give indication of the condition of the cable network infrastructure. -
Page 7: Figure 1: Monitoring With Sequenced Termination Units (Stu)
Splice/Security Sensors Figure 1: Monitoring with Sequenced Termination Units (STU) The ACU card in the 4200 CMS is connected to the conductive metallic conductor and applies -48 V dc to the cable network system. The cable metallic conductors are connected together at the splice enclosures. Uniquely addressed Splice Sensor Units (SSUs) are connected in parallel between the metallic conductor (across Tip and Ring in copper pair applications) and ground at each splice enclosures to detect water ingression. -

Figure 5: Line Alarm - STU Network Schematic ACU Monitoring (Using TSU Termination Sensors) The 4200 CMS uses an ACU card that can be configured for monitoring a cable network using a Termination Sensor Unit (TSU) and Branch Termination Sensors (BTS). The cable network system would be composed of lengths of cable joined by splices using Splice Sensor Units (SSU) with the main cable line terminated by one TSU sensor. -

S E R A N U A L The ACU card in the 4200 CMS applies a -48 V dc to the TSU cable metallic conductor network. In an ideal situation with no faults to ground the loop current (I ) would be 0.48 mA. -
Page 12: Splice Sensor Unit (Ssu) Operation
ON . With current now flowing through the sensor, the SSU transmits a digitally coded address to the 4200 CMS causing a Cable/SSU alarm . A triggered sensor causes an increase of 1.5 - 2.5 mA in the detection line current. A Cable alarm may be registered simultaneously if the cable alarm fault level threshold is set within this current range (Figure 10). -
Page 13: Figure 11: Bfs Installation Diagram
The sensor portion of the BFS is powered from the line monitoring voltage provided from the 4200 ACU card. This ensures monitoring and alarm functionality in the event of a complete loss of battery power at the remote site. The sensing circuit is powered from the monitored battery string. -
Page 14: Multiplexed Remote Sensor (Mrs) Operation
• Back-up Battery – Operation & Condition • Moisture – Humidity and/or pit water level Once a specific MRS input is activated, the input code is received by the 4200 ACU card which activates the alarm process on the 4200 CMS unit. Information regarding the location of the MRS and which input was activated is relayed in the Alarm Report via email, SMS, SNMP or modem communication. -
Page 15: Figure 12: Mrs Install Diagram
Figure 12: MRS Install Diagram The status of each MRS connected to the 4200 ACU card and its designated Line (1, 2, 3 or 4) can be tested to verify the operation of each unit. When a status test (end to end code check) is executed, each MRS will be polled and its STU code is expected to be received. -

Installation The following instructions will explain the installation of a 4200 Cable Management System that is used in conjunction with a 4200 ACU card for metallic cable conductor and sensor monitoring. A typical monitored cable network is illustrated in Figure 13 with the 4200 CMS unit located in the originating central office. -
