WIRING INSTRUCTION:

The RS-485 Wiring to the FW-RA-LED Module is
recommended to be Twisted Shielded Pair as
shown in the diagram. The wire gauge may be;
22 AWG up to
2000 ft.
20 AWG up to
4000 ft.
18 AWG up to
8000 ft.
The RS-485 wiring from the Fire Alarm Control
Panel to the Annunciator(s) must be point-to-point
from the FA Panel to the first Annunciator, then the
next Annunciator, and so on. No star-wiring or T-
tapping is allowed. Each RAM-208 Annunciator
Module has a 120 ohm End-of-Line Resistor on
its RS-485 Output terminals. This is removed on
all except the last wired Module.
The 24 VDC field wiring needs to be of an
appropriate gauge for the number of annunciators
and the total wiring run length. See the
Specifications section "Current Drain for Battery
Calculations", and calculate the Maximum current
for all Annunciators summed together ...
NOTE: Accidentally connecting any of the 24
VDC wires to the RS-485 wiring could
result in damage to the Annunciator
and/or to the Fire Alarm Control Panel that it is connected to !!!
