ABOUT THIS MANUAL
This manual is included as a quick reference for installation. For fur-ther

manual.
Note: This manual should be left with the owner/operator of this
equipment.
MODULE DESCRIPTION
The MIX-4070 SLC Short Circuit Isolators enable part of the commu-nication loop to continue operating when a short circuit occurs on it. An LED indicator blinks in the normal condition and turns on during a short circuit condition. Only LED of devices next to the short are steady on for easy identification of faulty SLC section. The module will automatically restore the entire communication loop to the normal condition when the short circuit is removed. The module is a hard-ware only device that does not require an address. There are no lim-its on number installed on the SLC as long as total loop current limit is respected. This is a low current device.

MOUNTING
Notice: You must disconnect power from the system before installing the
module. If this unit is being installed in a system that is currently
operational, it is necessary to inform the operator and the local authority
that the system will be temporarily out of service.
The MIX-4070 module is intended to be mounted in a standard 4” square back-box
(see Figure 2). The box must have a minimum depth of 2 1/8 inches. Surface
mounted electrical boxes (BB-400) are available from Mircom.
NOTE: The number of devices that may be installed between fault isolator
modules will vary depending upon the types of devices being isolated. Contact
the fire alarm control panel manufacturer for the isolator load ratings of
individual devices.
