2 D125B Dual Class B Initiating Module

24 VDC Applications

An auxiliary power supply is used in 24 VDC applications. The auxiliary power supply provides power for the module and all devices connected to the two loops.

Notice

The power supply is not provided with the unit. Any power supply installed must be UL listed for use with Bosch fire products.

The D130 Relay Module is used for 24 VDC applications. CMD 47 is used to reset 24 VDC smoke detectors. Refer to the control panel's operation and installation guide.

Unpowered initiating devices such as waterflow switches, manual stations, and heat detectors are installed without the D130 Relay Module.

Mounting Considerations

The D125B module mounts in the Bosch control panel enclosure using screws included with the unit. Use a D137 Mounting Bracket to install additional modules in the same enclosure, or when installing the D125B in an approved adjacent enclosure. Separate enclosures must be within 20 ft (6.1 m) of the control panel enclosure and connected by conduit.

Wiring Considerations

Notice

When used in a fire system, NFPA 72 prohibits this product from sharing a communications bus with non-fire devices.

The D125B needs to be electrically connected to the control panel's common terminal.
