KMD-5567 1 Installation Guide
Introduction
The KMD-5567 is installed at building exits and
entrances to provide surge suppression for one or
two pairs of low-voltage data signal lines. When
properly installed and wired, the KMD-5567 can
protect the digital communication circuitry from
lightning damage.
In smoke control applications, one KMD-5567 is also
required for the EIA-485 terminals of every control-
ler and repeater as well.
See Illustration 1 for a diagram and dimensions
of the module and terminal connector. The sup-
pressor consists of two parts, the Suppressor
Module (HPO-0066) and the Terminal Connector
(HPO-0067).

Installation and Wiring
Network Protection, Multiple Building
The KMD-5567 should be located near locations
where communication circuits enter and exit the
building. See Illustration 3.
1. Mount the module in a suitable enclosure using
the provided mounting holes.
NOTE: Orienting the unprotected terminals on the
same side as the incoming or exiting wiring
may simplify the wiring process.
2. Connect the incoming or exiting wires to the
unprotected side (pairs 3/5 and/or 7/9). See
Illustrations 2 and 3.
3. Connect the protected side pairs (2/4 and/or 6/8)
to the destination device wiring.
4. Connect an equipment ground to either Pin 1 or
Pin 10, but not both.
Individual Controller Protection
NOTE: This is required in smoke control
applications on every controller and
repeater.
1. Mount the module in a suitable enclosure using
the provided mounting holes.
2. Connect the EIA-485 wires from the previous
controller or repeater to the appropriate terminals
as shown in Illustrations 2 and 4.
2. If applicable, connect the EIA-485 wires from
the next controller or repeater to the appropriate
terminals as shown in Illustrations 2 and 4.
3. Connect the KMD-5567 “protected side” terminals
to the controller as shown in Illustrations 2 and 4.
4. Connect an equipment ground to either Pin 1 or
Pin 10, but not both.
