The B.D.I. Alarm System consists of a copper alarm strip assembly installed in conjunction with a rupture disc and a CDC alarm monitor. When the rupture disc bursts, the B.D.I. Alarm strip is severed, interrupting the electrical current through the strip. This initiates an audio and/or visual warning signal at the alarm monitor. The B.D.I. Alarm System is ideal for all installations where immediate notification of relief is required and especially in remote or isolated locations.
