MIX-4045-M Multi-Relay Module
Product Information
The MIX-4045-M multi-relay module is a device designed for
installation and use with a fire alarm control panel. It provides 8
form C (SPDT) contacts rated at 2A @ 30VDC or 0.5A at 125VAC
resistive loads from power limited sources. The relays are
programmable and can be individually switched by a compatible
panel. The module also supports group activation capability for
fast reaction time. The SLC is power limited and the module does
not supervise circuit connections to the relay contacts. The relays
are power limited if wired to a power limited source. The
MIX-4045-M is compatible with FX-400, FX-401, and FleX-NetTM FX4000
fire alarm control panels and meets UL 864, 10th Edition and ULC
S527, 4th Edition requirements for devices. The SLC and power
connections are on opposite corners of the device for easy
installation. The address of each module is set using the MIX-4090
programmer tool, and up to 240 units may be installed on a single
loop. The module has LED indicators for each relay to signal
activation (red). A green LED shows SLC communication status, and
two yellow LEDs indicate if a short circuit has been isolated on
either side of the SLC connection.
Product Usage Instructions
- Ensure you have read and understood the compatible control
panel instructions for the device’s operation modes and
configuration requirements. - Before performing installation or service, it is recommended to
disconnect the SLC line. - To mount the multi-relay module onto a DIN rail, follow these
steps:- Hook the multi-module device onto the bottom of the DIN rail
with three teeth. - Push the mounting clip upward with a flat screwdriver.
- Push the multi-module device onto the DIN rail and release the
clip.
- Hook the multi-module device onto the bottom of the DIN rail
- Refer to the wiring diagram for connecting loads to the
module’s relay contacts. - For alarm mode, connect the load on alarm 24VDC. For load
disconnected on alarm mode, connect the load on supply 24VDC. - The module provides six sets of normally closed (NC), common
(C), and normally open (NO) contacts. Refer to the wiring diagram
for specific connections.

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.
Note: This manual should be left with the owner or operator of this equipment.
DESCRIPTION The MIX-4045-M multi-relay module provides 8 form C (SPDT) contacts rated at 2A @ 30VDC or 0.5A at 125VAC resistive loads from power limited sources. The relays are programmable and a compatible panel can switch individual contacts as required. The module also supports group activation capability for fast reaction time.
The SLC is power limited and the module does not supervise circuit connections to the relay contacts. The relays are power limited if wired to a power limited source.
The MIX-4045-M is compatible with FX-400, FX-401 and FleX-NetTM FX4000 fire alarm control panels and is designed to meet UL 864, 10th Edition and ULC S527, 4th Edition requirements for devices.
The SLC and power connections are on opposite corners of the device for easy installation. The address of each module is set using the MIX-4090 programmer tool and up to 240 units may be installed on a single loop. The module has LED indicators for each relay to signal activation (red). A green LED shows SLC communication status and finally, two yellow LEDs indicate if a short circuit has been isolated on either side of the SLC connection.
