Blazon Strobe Lights
Blazon/3 | Blazon/4

Remote Override Generator
OG904

Splitters / Isolators
SB-1 and SB-2A

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 activated.  The xenon lamp is permanently connected.  The audible annunciator may be switched among constant, 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-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.

Blazon/4 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/4 will be activated.  The xenon lamp is permanently connected.  Circuitry is provided to sustain the Blazon/4 for 4 seconds after being triggered.  The xenon lamp has a flash rate of 2Hz, providing 8 flashes per cycle.  The Blazon/4 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.  Blazon/4 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, 120mA.  When calculating power supply requirements, you may consider the Blazon/4 as the approximate equivalent of 3 or 4 belt packs.

An OG904 can be fitted into any station which will also accept a microphone, i.e: master stations, headset stations (including beltpacks), or even another LS-3 talkback loudspeaker station.  The tone can be activated by a separate switch added to the sending station, or by its microphone on/off switch.  Since all Production Intercom loudspeaker stations already include the detection and activation circuitry, the only added cost is the OG904 generator card, and its installation in the sending station.

The SB-1 provides a convenient method of splitting a single circuit run into as many as 4 spurs. It has one input and four output XLR connections.  One cable run from a system master or power supply can be run to a remote location then be split among several stations.  Daisy chaining can be minimized, eliminating the need for two cables being connected to belt packs.
