The Building Status Unit III (BSU III) is a local alarm notification device. This an excellent device to use when personnel at the site must be made aware of critical, major, and/or minor alarms.
The BSU III monitors three discrete alarms. For both local and remote alarm monitoring, the BSU III is connected to the control outputs of a NetGuardian alarm remote or the AV relays of a T/Mon master station. The NetGuardian (or T/Mon) intelligently latches its contact relays whenever critical, major, and/or minor alarms are standing, and the BSU III reacts by providing audible and visual notification of alarms through its integrated 3 alarm notification LEDs and an audible speaker signal.
The BSU III is typically placed near the exit door of unmanned sites, so visiting technicians are alerted of standing alarms before they leave the site. At manned sites, the BSU III should simply be placed where it can be heard or seen by technical personnel.
The BSU III can be used with many DPS Telecom masters and alarm remotes, including:
Audio/visual notifications are acknowledged by pressing the Local ACK button on the bottom of the unit. The speaker can be silenced using the volume control. You can also reverse the input polarity of the alarms.
