MGC MIX-4001 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.
SPECIFICATIONS
Dimensions: 6” Diameter, 5/8” Height Wiring range on all terminals: 22 to 12 AWG
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:
- Position the detector centrally on its adapter base ensuring it is level.
- Rotate clockwise applying gentle pressure. The detector will drop into its keyed location.
- Continue to rotate clockwise a few degrees until the detector has fully engaged in the adapter base.
- 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.
