Performance: Blazon 3 is triggered by the same voltage which 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/3 will be ac- tivated. The xenon lamp is permanently connected. The audible annunciator may be switched among con- stant, pulsed, and off. Circuitry is provided to sustain the Blazon 3 for 4 seconds after being triggered. The xenon lamp has a flash rate of 2Hz, providing 8 flashes per cycle.
The Blazon 3 is connected to the headset intercom system in the same manner as a belt pack. It has two 3-pinXLR connectors on the rear panel. By convention (to differentiate from microphone inputs) the female connec- tor is designated as input. The male connector is provided for looping onwards to the next station in the sys- tem. Reversing these connections will not affect operation.
Blazon 3 is powered by the intercom power supply and requires no batteries or other external power source. In its ‘Ready’ mode it draws only 21.1mA; with the strobe active, 56mA, and; with the strobe and audible annunci- ator, only 108mA. When calculating power supply requirements, you may consider the Blazon 3 as the ap- proximate equivalent of 3 or 4 belt packs.
Durability: The ribbed, extruded aluminum case; glass-filled nylon end bezels; internal support system for thePC board, and; best quality XLR-type connectors, all contribute to the Blazon 3’s ability to withstand rough us- age.
Value: The comparatively low price of the Blazon 3 is made possible by the minimized assembly cost resulting from simplicity of construction.
Compatibility: Blazon 3 is compatible with Clear-Com® and other lesser known (unbalanced 200) party-line headset intercom systems.
