e-Q2B Siren System

Convergence Network Control Head
The Convergence Network control head digitally transmits and prioritizes end-user commands. The
control head/amplifier interface uses solid-state digital decoding, which minimizes interconnection
complexity. The control head allows the user to operate several siren functions. The traditional Q Wail
can be activated in automatic or manual modes. Additional features include a Q Yelp, Q Brake, digitally
recorded Air Horn, PA/radio rebroadcast, and push-to-talk via an integral microphone. PA volume can be
adjusted by the user with a volume control potentiometer.
LED Indicators
Green LEDs on the side of the siren amplifier indicate when power is supplied to the amplifier, when
output is available and when a load is connected. Red LEDs indicate a speaker short or thermal overload.
All buttons on the control head glow amber when the system is on. Pressed buttons glow brighter to
indicate that the function they control is active.
