Description
The addressable Module 55000-847 serves for the
line-monitored integration of contact detectors, such
as manual call points, sprinkler system contacts or
supervising contacts, into the bidirectional communica-
tion on the ADM loop with Apollo/Discovery protocol.
Furthermore, it can be used to actuate external devices
by means of a relay output with two dry change-over
contacts, via the ADM loop. In addition to the monitored
input and the relay output, the module has an opto-cou-
pled input for monitoring an external voltage.
The address is easily selected by means of a built-in DIL
switch. Status LEDs indicate the condition of input and
output. The module has an integrated dual-isolator and
is fi tted into a plastic case.
