ANN-BUS Devices
Mounting/Installation
The ANN-RLY relay module can be mounted inside the FACP main circuit board chassis. An
optional ANN-MBRLY mounting bracket allows mounting of the ANN-RLY in the lower right
hand corner of the FACP cabinet instead of or in conjunction with the mounting provisions under
the main FACP circuit board chassis. Refer to the documentation supplied with the module for
information on installation.
