Beacons “Blazons”

Pro Intercom Blazons are triggered by the same voltage that lights the normal signal lamps in the intercom system. Whenever any signal lamp button on any station in the same circuit is pressed, the Blazon will be activated.
Circuitry is provided to sustain the beacon for 4 seconds after being triggered. The xenon lamp has a flash rate of 2Hz, providing 8 flashes per cycle.
The Blazon is connected to the headset intercom system in the same manner as a belt pack. It has two 3-pin XLR connectors on the rear panel. By convention (to differentiate from microphone inputs) the female connector is designated as input. The male connector is provided for looping onwards to the next station in the system. Reversing these connections will not affect operation.
Blazons are powered by the intercom power supply and require no batteries or other external power source. In ‘Ready’ mode they draw only 21.1mA; with the strobe active, 56mA, and with the strobe and audible annunciator, only 108mA. When calculating power supply requirements, you may consider the Blazon as the approximate equivalent of 3 or 4 belt packs.
Blazons are compatible with Clear-Com® and other unbalanced party-line headset intercom systems.


The Blazon180 incorporates a front mounted rectangular xenon lamp to limit the visibility of the flashes to 180°.
