signal and thus prevent reflections. Fortunately, the controller makes
network termination simple as resistors are included on the board.
These can be switched in and out of network by moving the "EOL"
jumpers as shown in the figure on page 12. More information on RS-
485 wiring is published by Maxim Integrated in the TUTORIAL 763
Guidelines for Proper Wiring of an RS-485 (TIA/EIA-485-A) Network .

Settings for Specific Transmitters

Honeywell Sensepoint XCD Transmitters must be configured for 9600
baud, no parity, and a unique address. Honeywell XNX Universal
Transmitters must be configured for 9600 baud and a unique address.
Information on configuring each transmitter is in the associated
technical manual.
Some sensors consume multiple addresses on the 301C. Specifically,
the 301EM consumes 4 addresses regardless of the number of
sensors connected. Additionally, the IAQPoint2 consumes 3
addresses if fitted with the optional temperature / humidity sensor.
Please allocate proper address spacing for applications utilizing a
mixture of sensors on a single system.

Relay Output

The relay output can withstand up to 5A at 30Vdc or 250Vac resistive
load. Relays can be used to activate horns and strobes. Although
each relay is programmed with a default setting (below), they can be
configured using the controller programming menu.
By default, the relays are normally de-energized and will go energized
when events occur. However the relays can be configured for
"failsafe" or normally-energized. If so, events will drive them to de-
energized.
