1.5.2. Wiring Diagram
A copy of the wiring diagram is included in the assembly drawing located
at the end of this document.
1.5.3. Alarms
1.5.3.1. Intrusion
The enclosures are equipped with pin switches on both the front and
rear doors that activate and intrusion alarm when a door is opened.
The TGB notifies the TGB controller of the alarm.
A feature of the outdoor enclosures intrusion switch is the ability to
“pull out” the switch to cancel the alarm. The switch has a 30-minute
mechanical delay, after which the intrusion alarm will again be
asserted.
1.5.3.2. Temperature
The TGB is equipped with high (120F) and low (41F) temperature
alarms. The TGB notifies the TGB controller of the type of alarm.
1.5.3.3. Power System
The rectifier has several alarm outputs to signal different types of faults
associated with the power system.
Low Voltage Alarm – Asserted upon loss of AC Commercial Power.
Rectifier Failure – Asserted when DC output voltage is out-of-range.
Load Fuse Failure – Asserted when one of the load fuses (Fan, Heat
Exchanger, Intrusion Alarm) opens.
Battery Failure – Asserted when output voltage drops below
threshold, Low voltage disconnect is activated, or Bypass switch is in
Bypass position.
1.5.4. RF Subsystem
1.5.4.1. Spark Gap
The antenna bulkhead connector is a Gas Discharge Tube Surge
Arrestor designed to shunt lightening induced transients to ground;
thereby protecting the TGB electronics from damage. The arrestor
contains a replaceable gas tube element that should be inpected
regularly are replaced as necessary.
1.5.4.2. Cavity Filter
The cavity filter is a frequency selective device designed to protect the
RF front end from overloading by out-of-band signals. The cavity filter
assembly is tuned and assembled as a unit. No cables or connectors
should be changed/replaced, nor should any adjustments be made to
the tuning screws.
