allowing individual control of signal rate and on-off state for
each device. The MIX-4003-LF must be used with a compatible MGC
control panel.
Key Components:
- Wiring Tabs
- Sounder Base Assembly Components
- MIX-4000 Series Detector
Product Usage Instructions:
Installation:
- Mount the mounting plate from the Sounder Base Assembly
Components on the electrical box. - Perform all wiring using integral screw connectors.
- Visually inspect connections before mounting the sounder base
itself. - Plug in and secure the enclosure containing the electronics,
sounder base, and detector.
Wiring:
Before installation, refer to the compatible control panel
instructions for operation modes and configuration requirements. It
is advised to disconnect power from SLC and NAC lines before
installation. Follow these steps:
- Determine the total current draw of devices.
- Ensure the total current draw does not exceed NAC output
capacity and SLC line capacity of the panel. - Consider voltage drop to ensure the last device operates within
its rated voltage. - Consult the fire panel installation manual for wire resistance
and length guidance.
FAQ:
Q: Can I paint or alter the factory finish of the MIX-4003-LF
sounder base?
A: No, do not paint or modify the factory applied finish in any
way.
Q: What are the key components of the MIX-4003-LF sounder
base?
A: The key components include Wiring Tabs, Sounder Base Assembly

SOUNDER BASE DESCRIPTION
The MIX-4003-LF sounder base is designed to meet UL268/ULC S529 requirements for smoke detector, UL521/ULC S530 requirements for heat detector, and UL464/ULC 525 requirements for audible notification appliances.
The MGC MIX-4003-LF provides localized alarm sounding capability for the MIX-4000 family of fire detection devices. They can be used in place of external sounders to minimize installation cost and footprint while allowing individual control of signal rate and on-off state for each device. The MIX-4003-LF must be used with a compatible MGC control panel. Operational mode and levels are selected at the Fire alarm panel through the MGC MP configuration tool.
The MIX-4003-LF produces a low frequency alarm signal at sound pressure levels shown in table 2.

The mounting plate in figure 2 is mounted first on the electrical box and all wiring is done on integral screw connectors. The connections are apparent and can be visually inspected before the sounder base itself is mounted. Then, the enclosure containing the electronics, the sounder base and the detector can be plugged in and secured.
Note: This device should be installed as per applicable requirements of the authorities having jurisdiction.
WIRING
Before installing this device seek guidance from the compatible control panel instructions for the device operation modes and the configuration requirements. It is recommended to remove power from SLC and NAC lines before performing the installation.

Use the information in this document to determine the total current draw of the devices. The total current draw of the devices must not exceed the NAC output capacity and the SLC line capacity of the panel. In all cases, the installer should consider the voltage drop to ensure that the last device on the circuit operates within its rated voltage. Please consult fire panel installation manual for guidance on wire resistance and length. For maximum horn operating current, please refer to table 4.
Do not loop signal circuit field wires around terminals. Electrical supervision requires wire run to be broken at each end.
Correct: Wire run is broken
Wrong: Wire is looped around terminal

Note: Wiring must be in accordance with CSA C22.1, Canadian Electrical Code, Part I, Safety Standard for Electrical Installations, section 32 and/or NFPA 70.
CAUTION
FOR SYSTEM SUPERVISION, FOR ALL TERMINAL TAPS, DO NOT USE LOOPED WIRE UNDER TERMINALS. BREAK WIRE RUN TO PROVIDE SUPERVISION OF CONNECTIONS.
ATTENTION
NE PAS UTILISER DE FILS EN BOUCLE SOUS LES BORNES. INTERROMPRE LA CONTINUITÉ DES CÂBLES POUR PERMETTRE LA SUPERVISION DES CONNEXIONS.
MOUNTING
The mounting plate is compatible with 3″ by 2″ single gang device boxes, 3-3/4″ by 4″ double gang boxes, 4″ by 2″ single gang utility boxes, standard 4″ by 4″ boxes, and standard 4″ octagon boxes.
1. Attach the mounting plate to the electrical box with two mounting #8-32 x 3/4″ screws.
2. Slide down the sounder base enclosure until the connection blades touch the clips on the mounting plate.
3. Secure the mounting plate with securing M3 x25 mm screws.

MOUNTING THE DETECTOR
If the detector type and address is required to be visible from the outside, break the address tab inside the detector base and insert it in the outer rim of the base. See figure 7.

The detector can then be placed on the top base using the following steps (figure 8):
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 9).

The sounder base is capable of producing a variety of tone patterns, including the distinctive three-pulse temporal pattern (ANSI Temporal 3) fire alarm signal now required by NFPA 72 for commercial and residential applications and is configured in this default mode. The available tones are Continuous, ANSI Temporal 3, 20 BPM, and March. Refer to the appropriate fire alarm control panel manual for more information on selection of these tones. NOTE: For NFPA 72 Installations, the Temporal 3 tone should be used for emergency and public mode evacuation. The use of other tone styles will be at the discretion of the local Authority Having Jurisdiction (AHJ).
