ABOUT THIS MANUAL
This manual is included as a quick reference for installation. For fur-ther
information on the use of this device with a FACP, please refer to the panel’s
manual.
Note: This manual should be left with the owner or operator of this
equipment.
MODULE DESCRIPTION
The MIX-4042 Analog interface module is designed to operate with a listed
compatible intelligent fire system control panel. It can be configured to work
with conventional two wires or 4-20mA devices. An external listed power supply
can be connected to several MIX-4042 to provide power to the devices while
remaining electrically isolated from the FACP. Each MIX-4042 will monitor the
current used by the devices and will report alarms and troubles accordingly.
The operational mode of the MIX-4042 is set through the panel configuration
tool. This tool will also set other parameters of the device such as reset
time for conventional devices or alarm levels for the 4-20mA operation. When
set for conventional devices, the module will automatically handle Class A or
Class B lines. The MIX-4042 has an internal EOL. resistor for Class A lines. A
MP-300 end of line resistor must be used for Class B wiring. The address the
MIX-4042 is set using the MIX-4090 programmer tool and up to 240 units may be
installed on a single loop. The module has a panel controlled LED indicator
that will blink during normal standby operation and will be steady ON when the
devices has detected an off-normal condition.
Conventional two wires fire-alarm devices that are compatible with the
MIX-4042 are listed at the end of this document. 4-20mA devices will generate
monitor events on the FACP; the MIX-4042 can be used with most two wires
4-20mA non-fire use application devices.
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-4042 module is intended to be mounted in a standard 4” square back-box (see Figure 2A). The box must have a minimum depth of 2 1/8 inches. Surface mounted electrical boxes (BB-400) are available from Mircom.
WIRING:
Note: This device should be installed as per applicable requirements of
the authorities having jurisdiction. This device shall be connected to power
limited circuits only.
- Install the module wiring as indicated by the job drawings and appropriate wiring diagrams.
- Use the programmer tool to set the address on the module as indicated on the job drawings.
- Mount the module in the electrical box as shown in figure 2B.
Note: The external power source shall be Listed for used in fire alarm system, and that has ground fault detection capability.

Important note
When using the MIX-4042 as a conventional Zone module with alarm verification,
the following section of the FACP panel door label must be completed with the
relevant delay information.
Control Unit Alarm Delay is 25 seconds for the MIX-4042. Delay for smoke detectors can be found in the installation instructions supplied with the devices.
