Alarm Contacts (Plug-In Terminal Block)
Normally open (NO) and normally closed (NC) alarm contacts are provided on the rear panel of the
TRACER 5045 system. In normal operation, the NC contact is electrically connected to the common
contact (COM) and the NO contact is isolated. During an alarm condition, the NC contact becomes
isolated and the NO is electrically connected to COM. This allows alarm conditions to be reported to
external alarm monitoring systems.
DC Power Connection (Plug-In Terminal Block)
The TRACER 5045 can operate from a supply between 21 and 60 VDC, with either polarity referenced to
ground, and consumes less than XXXX Watts (W). Power supplies should be able to provide up to XXXX
W at the selected voltage. Current required (in Amps) is determined by dividing the power consumed (in
Watts) by the applied voltage (in Volts). For example, at 48 V, TRACER 5045 would draw approximately
XXXX A (XXXX W/48 V).
Fuse
The fuse holder, accessible from the rear panel of the TRACER 5045, accepts a generic 1 A, 250 V, 2-inch
slow-blo fuse.
Antenna Interface (N-Type connector)
The ANTENNA interface (N-Type connector) connects to the customer-supplied antenna using standard
antenna feedline cable. When determining the cable specifications for your application, refer to Section 2,
Microwave Path Engineering Basics (System Losses (L) on page 18) for a discussion on cable length and
loss factors.
