Alarm Contacts (Plug-In Terminal Block)

An RF link down condition is indicated with both normally open (NO) and normally closed (NC) alarm contacts on the rear panel of the TRACER 4106/4206 system. In normal operation, the NC contact is electrically connected to the common contact (COM) and the NO contact is isolated. When the RF link drops, the NC contact becomes isolated and the NO is electrically connected to COM. This allows RF down conditions to be reported to external alarm monitoring systems.

DC Power Connection (Plug-In Terminal Block)

The TRACER 4106/4206 can operate from a supply between 21 and 60 VDC, with either polarity referenced to ground, and consumes less than 20 Watts (W). Power supplies should be able to provide up to 30 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 4106/4206 would draw approximately 0.417 A (20 W/48 V).

The + terminal of the DC power connection must be connected to the most positive voltage rail, while the

terminal must be connected to the most negative voltage rail. For example, a +24 V source should be delivered to the TRACER 4106/4206 by connecting +24 V to the + terminal of the TRACER 4106/4206 power terminal block and ground (the most negative voltage) to the TRACER 4106/4206 – terminal. Alternately, a -48V supply should be delivered to the TRACER 4106/4206 by connecting ground (the most positive voltage) to the + terminal of the TRACER 4106/4206 power terminal block and -48 V to the – terminal.

If the power supply voltages are incorrectly connected to the TRACER 4106/4206 system, the fuse will blow.

Fuse

The fuse holder, accessible from the rear panel of the TRACER 4106/4206, accepts a generic 1A, 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.
