INSTALLATION AND MAINTENANCE INSTRUCTIONS
ABOUT THIS MANUAL
This manual is included as a quick reference for installation. For further
information on the use of this device with a FACP, please refer to the panel’s
manual. For more information regarding maintenance, testing, spacing, and
locating detectors, please refer to the LT-9420 MIX-4000 series detector
technical bulletin.
Note: This manual should be left with the owner/operator of this
equipment
DETECTOR DESCRIPTION
The MIX-4030 heat detector continuously measure ambient temperature and
reports it to the Fire-Alarm panel using a fully digital communication
protocol. It can be set to report an alarm when sampled temperature exceeds
135F (57C) or 175F (79C). Excessive temperature rises can also be reported if
the detector is configured for rate-of-rise operation. The MIX-4030 must be
used with a Mircom series 4000 compatible control panel. Operation mode is
selected at the Fire alarm panel through the Mircom configuration tool. It
also has a remote output that can be controlled by the panel. Please see
specifications for compatible devices that can use the remote output feature.
Note: MIX-4030-ISO is equipped with a bi-directional short-circuit
isolator to help protect against wiring faults that may otherwise result in a
loop failure. 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 detector must be installed on a ceiling or wall using a compatible base. SLC line and remote output connections for the most common base MIX-4001 are show in figure 2. 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. The detector address should be programmed using the MIX-4090 hand-held device before inserting the detector on the base. Addresses 1 to 240 can be used for any device on a SLC loop. Each device on a loop must have a unique address. 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 2 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 adaptor 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 NOTES ON DETECTOR INSTALLATION
Disconnect loop power before installing the detector. This detector comes with
a dust cover to protect the device during shipping and when first installed.
It is not intended to provide complete protection against contamination,
therefore, detectors should be removed from their base before construction,
major redecoration or other dust producing work is started. Dust covers must
be removed before the system becomes operational. Heat detectors should
installed away from normal heat sources. Do not use in locations where ambient
temperature is within 20F (10C) of the alarm setting. Long term ambient
temperature should not exceed 120F (49C). When configured for rate of rise
operation, do not use heat detectors in locations such as an heated building
entrance where large temperatures swings can be expected. Smoke detectors are
not to be used with detector guards unless the combination has been evaluated
and found suitable for that purpose. 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.
