2.3 Connecting 2-Wire AML Devices
The 2-wire addressable devices are connected to the STR+ and STR-
terminals on the PC5100. All devices can be home-run, t-tapped or
connected in a daisy chain. Please refer to the diagram below:
The wiring length of each addressable loop is restricted to the following
distances, depending on the amount of current required (see Section
2.2 "Calculating Current Draw"). Consult the wiring chart on the next
page.
For longer wire runs, you can split
the addressable devices onto two
or more loops from the STR termi-
nals. For example, 32 AMB-300
detectors (2.5mA each) take 80mA
total. In one 18AWG wire run, this
would allow a maximum length of
720 feet (220 m). If you split the 32
devices into two wire runs of 16
detectors each, using 18AWG wire,
each wire run could be 1736 feet
(529 m) long. See the diagram on
the right.
