MIX-4001 / 4002 DETECTOR BASE
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/operator of this
equipment
DETECTOR BASE DESCRIPTION
The MIX-4001and MIX-4002 bases are used to interface series 4000
detectors to the SLC line and remote devices. The base can be wired
and secured to a back-box during building construction, allowing the
detector to be installed later, when premises become free of dust and
other contaminants. The MIX-4001 and MIX-4002 both have a set of
mounting holes covered by the detector head. These are used to
mount the base to single gang boxes, 3.5" square boxes, and 4"
octagonal boxes. The MIX-4001 has an extra set of outer holes,
covered by a removable ring, for 4" square boxes (see figure 2).
When the base is secured to the box, the ring is placed back to cover
the mounting screws heads. A breakable flat tab in the center of the
base can be cut and inserted in the base outer edge then pen
marking or a label can then be used to identify the device.
Before installing this device please thoroughly read this manual and
refer to the applicable codes for guidance on location, spacing and
acceptable use. Also seek guidance from the compatible control
panel instructions for the device operation modes and the
configuration requirements.
Note: If the detector is used with the remote indicator, then the
voltage value of the detector must be at least 18V as the indicators
do not operate below 18V.

INSTALLATION
This base may be installed over a 4" square (MIX-4001 only), 4"
octagonal, 3.5" octagonal, or single gang box. The mounting may be
performed on either the ceiling or the wall. SLC line and remote
output connections for the MIX-4001/4002 base are show in figure 1.
A twisted pair cable should be used for the SLC line. If a shielded
cabled is used, connect the shields to the proper terminal on the
base. Do not connect shields to earth ground. If a ground continuity
wire is required by the local code, it should be a separate conductor.
Please note that shielded cables may reduce the SLC loop length
that can be achieved due to their high capacitance.
A breakaway tab inside the base can be inserted in the outer rim of
the base to visibly identify each detector with their address. See
figures 1, 3, and 4. The detector can then be placed on the base
using the following steps:
1. Position the detector centrally on its adapter base ensuring it is
level.
2. Rotate clockwise applying gentle pressure. The detector will drop
into its keyed location.
3. Continue to rotate clockwise a few degrees until the detector has
fully engaged in the adapter base.
4. When the detector is firmly engaged, check the alignment of the
raised reference marks on the detector and on the base (figure 4).
IMPORTANT NOTE ON BASE INSTALLATION
Disconnect loop power before installing the base.
When duplicate terminals are not provided to facilitate monitoring of
the installation wiring connections, and there is no provision to
prevent looping an unbroken wire around or under a terminal, the
word "CAUTION" and the following or equivalent text in letters not
less than 2.38 mm (3/32 inch) high shall be included on the
installation drawing: "FOR SYSTEM MONITORING - FOR
TERMINALS "Loop out (+)" AND "Remote Device (+)", DO NOT
USE LOOPED WIRE UNDER TERMINALS. BREAK WIRE RUN TO
PROVIDE MONITORING OF CONNECTIONS.
