MEDC product families on this page
Visual signals include the XB15 xenon beacon, the LD15 LED beacon and the SM87 beacon family with its SM87LED version, for Zone 1 and Zone 2 areas. The DB3 is the alarm sounder. Manual alarm devices are the BG manual call point and a manual release unit from the BG2 call point series, listed as BG2E. The SM87JB junction box completes the field wiring. These devices are ordered with long codes such as SM87BGLAD1T1B1NNRAS or BGEB4B6B1DDCF7R, in which each block of characters selects an option.
Where MEDC signaling equipment is used
MEDC beacons and sounders announce fire, gas and process alarms on production platforms, in gas plants, refineries, chemical plants, loading terminals and marine vessels. Call points give personnel a way to raise the alarm by hand, and the same devices are wired into fire and gas panels from many system builders.
MEDC products we list
Ordering MEDC beacons and call points: what we need
The complete order code from the label or the project datasheet is the best starting point. If you are selecting from scratch, send the supply voltage, lens color for beacons, tone and sound level for sounders, enclosure material and finish color, cable entry size and number, the certification required and the ambient temperature. For call points add the switch arrangement, any series or end-of-line resistor values, and label or duty plate text.
