Chapter 2: An Overview of the Convergence Network
SmartSiren Platinum Convergence Network

Programmable Input Circuits
Both models of the siren amplifier/relay modules have connections for four relay input circuits. Relay
inputs 1 and 2 are active-low inputs that activate a switch when pulled to ground. Relay inputs 3
and 4 are active-high inputs that activate a switch when pulled to 12 Vdc battery voltage. The inputs
are most commonly used for switches that send a signal to the siren amplifier/relay module when
a condition in the vehicle changes. Changes may include the opening of a trunk or door, a rise in
vehicle temperature, or the release of a gun lock.
The control head has connections for four active-low inputs that activate when pulled to ground.
Similar to the relay circuits, they can be configured to operate with the Convergence system control
head or with the configurable switches on the steering wheel of the Ford Police Interceptor.
LED Indicators and Visual Diagnostics (Model SSP3000B Only)
LEDs visible just below the surface of the siren amplifier/relay module indicate when power is
supplied to the auxiliary outputs and if the module is transmitting and receiving data. LEDs also
indicate when a signal is received by the four input circuits and if the lightbar is functioning.
Externally mounted mini-blade fuses for the siren, horn-ring circuit, SignalMaster, and auxiliary
relays have LEDs that glow when the fuse fails, making them easy to spot.
All buttons on the control head glow when the system is on. Pressed buttons turn bright to indicate
that the function they control is active. LEDs under the SmartSiren logo mimic these active
SignalMaster patterns: Left, Right, Center-Out, or Warn patterns 1 to 4. An LED glows over the
position in which the slide switch is placed.
