2.4 Mounting Addressable Modules
The HPFF12 and the HPFF12E are designed to mount Honeywell Fire Systems addressable control
or relay modules on the Control circuit board inside the power supply cabinet. This allows power to
be fed from the Auxiliary output directly to the module, if needed, without running the power wires
outside the cabinet. For a list of compatible optional modules that can be connected to the Auxiliary
output, see Appendix A, "Device Compatibility". Two single output modules may be mounted
directly above each other if required by applications such as Split Alarm or Selective Silence.
Alternately, two outputs of a 6-output addressable module can also be used and mounted on the
Control board.
2.4.1 Mounting Modules from Honeywell Fire Systems
Addressable modules can be mounted directly to the Control circuit board as shown in Figure 2.14
for the wall cabinet. This allows wiring to remain in the cabinet. Two modules can be mounted on
top of each other if the application requires two independent inputs, such as silencing. Alternately,
two outputs of a six-output addressable module can also be used. The six-output module can also
be mounted directly on the Control board.
Mounting addressable modules on the Control circuit board is also possible in the HPFF12CM(E)
units. However, the six-output module must be mounted in an optional multi-module chassis if used
in the large cabinet enclosure.
See Section 2.5, "Power-Limited Wiring Requirements".
