Description

The D-BZR is the ideal choice in installations requiring an audible alert. Rear-panel terminals permit connection of a trip signal, a remote reset button, external power supply, and a jumper to set the audible alert level. The D-BZR is activated when the TRIP input is momentarily connected to ground. The BZR then sounds the alert and remains in the alert mode until reset by either the front-panel RESET button, or by a remote reset button.

Normally, the D-BZR latches in the alert mode. Alternately, the D-BZR may be configured to sound the alert only while the TRIP terminal is grounded. This may be accomplished by installing a jumper from the remote RESET to ground. For use in confined areas, the standard alert may be too loud. The level may be reduced by removing a jumper provided on the rear-panel terminal block. A front-panel LED lights when the module is in the alert mode. If several D-BZRs are installed at a common location, this visual indication shows the operator which unit is tripped.

The D-BZR power supply input accepts 24 Volts ac or dc. The D-BZR is a negative ground-referenced product. In the unlikely event it is connected on a common 24 Vac supply together with equipment which is positive ground-referenced and not transformer isolated, a ground fault may occur. The D-BZR automatically detects such a fault and disconnects itself from the power input.
