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-4020 smoke detector continuously checks air obscuration and reports it
to the Fire-Alarm panel using a fully digital communication protocol. It can
also measure ambient temperature and can be set to report an alarm when
sampled temperature exceeds 135F (57C). Excessive temperature rises can also
be reported if the detector is configured for rate-of-rise operation. The
MIX-4020 must be used with a Mircom series 4000 compatible control panel.
Operational mode and levels are 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-4020-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 re-decoration 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 pre-vent 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 MONITOR-ING OF CONNECTIONS.
