communications. The PC 372 may be located up to 2200’ (RS-485 cable length) from the controller. The flashhead
may be located up to 375’ (using #10 wire) from the power converter.
Installations of FTS 270 systems requiring L-810 markers is accomplished by using the MKR 371 connected to the
MKR 372 MARKER INTERFACE as its power converter. The MKR 372 MARKER INTERFACE also communicates with
the FTC 270 via RS-485 communications.
The FTC 270 provides overall system control including mode control, synchronization, alarm collection and
notification. Isolated RS-485 provides robust and highly reliable communication between all units.
The PC 270 and PC 372 are both AC powered, and are not sensitive to input power phase. Both PCs have an
operational voltage range of 100-277 VAC, 50/60 Hz with no modification necessary to the input power module.
The FTC 270 and MKR 372 MARKER INTERFACE have an operation voltage range of 120-240 VAC, 50/60 Hz.
This manual provides guidance and recommendations for the installation, operation, and troubleshooting of the
lighting system. Please read this document in its entirety before installation.
