PA300-CN Siren Amplifier
Connections to the Model 660100 Relay Module/Two-Channel Flasher
The Model 660100 Relay Module/Two Channel Flasher is included with the Model 690200 PA300-CN
siren amplifier. It controls up to four different devices of which two can be activated as a two-channel
flasher. The Model 660100 uses less than 15 mA of power when connected to the vehicle battery with
the network disabled. When the network is enabled, an additional 25 mA is consumed from the network
power lines during standby. To draw no current, we recommend that the Model 660100 be powered
with an in-line switch capable of handling the total switch current of the active device.
Connect the serial cable included with the relay module to any one of the three serial connectors on the
front of the PA300-CN siren amplifier (Figure 3.4). For more detailed instructions, refer to document
No. 2562431, “Model 6600100 RS485 Relay Module/Two-Channel Flasher."
