7. Alternative Sign Arrangements
Mimic Signs / Connecting more than 7 Signs
In systems that require more than 7 signs, additional signs may be installed by connecting to the 24VDC TRIGGER
terminals located in each sign. This allows connected signs to mimic the operation of a sign that is connected to
the STATUS SERIAL (RS485) circuit. Note: signs can only mimic other signs of the same type (A "Do Not Enter"
Sign can only mimic another "Do Not Enter" Sign).
The 24VDC trigger function of each sign connected to the STATUS SERIAL (RS485) circuit can support up to 3
additional signs.
There is no need to configure the address or sign function switches, however the internal buzzer and flashing
functions can still be adjusted separately.
IMPORTANT – An additional external power supply OR an upgraded power supply in the FIP is required for any
additional devices over the standard maximum of 7 devices. Each sign has a current draw of 140mA. When installing,
power supply (including backup supply) must be assessed to ensure that it will be adequate.
While it is possible to use this configuration with fewer than 7 devices, it is not recommended.
The LCS must be installed on the STATUS SERIAL (RS485) circuit. It cannot be used as a mimic device.
