T1 Connections (RJ-48C)
The physical T1 interfaces are provided by eight RJ-48C jacks that comply with the applicable ANSI and
AT&T
®
standards.
Alarm Contacts (Plug-In Terminal Block)
Normally open (
NO
) and normally closed (
NC
) alarm contacts are provided on the rear panel of the
TRACER 4108/4208 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 4108/4208 can operate from a supply between 21 and 60 VDC, with either polarity
referenced to ground, and consumes less than 21 Watts (W). Power supplies should be able to provide up to
25 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 4108/4208 would draw
approximately 0.438 A (21 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 4108/4208 by conn24 V to the + terminal of the TRACER 4108/4208
power terminal block and ground (the most negative voltage) to the TRACER 4108/4208 – terminal.
Alternately, a -48V supply should be delivered to the TRACER 4108/4208 by connecting ground (the most
positive voltage) to the + terminal of the TRACER 4108/4208 power terminal block and -48 V to the –
terminal.
