SYSTEM CONFIGURATION (ZONES)
SETTING UP THE 4208
The 4208 is an 8 zone RPM which is connected directly to the polling loop.
Each zone is end-of-line-resistor supervised and can be used with either
open-circuit or closed-circuit devices. Zone numbers used with the 4208 are
pre-assigned in groups of 8 (except the first group) beginning with zone 10,
and are set via the unit%DIP switches. Note that if more than one 4208 is
used, the system limits the number of zones supported by the first group of
addresses to 7 (zones lo-16 available). If only one 4208 is used, the first
group of addresses can be expanded to 8 zones (zones lo-17 available) by
entering a 1 in program field ‘86. See the PROGRAMMING section tar
information regarding this programming option. See the PROGRAMMING
section for information regarding the use of more than one 4208.
The first two zones are DIP switch programmable for fast response (10
millisecond). Zones connected to this module are factory set for 400
millisecond response. The first six zones are high current zones for use with
mechanical sensors. The last two zones can support only low current sensors
(reed switches, etc.).
IMPORTANT!: The 4208 does not support P-wire smoke detectors.
