DC Power Connection
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 0.42 A (25 W/48 V).
Alarm Contacts
Normally open (NO) and normally closed (NC) alarm contacts are provided 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. 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.
T1 Connections
The physical T1 interfaces are provided by 4 RJ-48C jacks that comply with the applicable ANSI and
AT&T
®
standards.
