u Provides point identification of initiating devices
u Supervises wiring to devices for circuit integrity
u Expands the number of points in the system
The D8125 Addressable Expansion Module works with
the D9127U or D9127T POPIT Modules to provide
multiplex technology that combines zone or point
supervision with individual device addressing on one
pair of wires. Use the D8125 to provide expansion
beyond the standard number of control panel zones,
up to a total of 238 points. Each D8125 module can
fully supervise 119 D9127U or D9127T POPIT Modules.
System overview
Each D8125 installs in the control panel enclosure or
in an adjacent approved enclosure. Future system
expansion is very economical as D9127U or D9127T
POPITs can be spliced in anywhere along the two-wire
data expansion loop from the D8125 module.
The D9127 is a compact, addressable device that is
suitable for applications where specifications call for
point identification from each initiating device or
series of devices. The units are small, and easily
installed in standard outlet boxes, above false ceilings,
closets, or other accessible locations.
The D8125 includes a 33 kΩ end-of-line (EOL) resistor.
Install the resistor at the farthest point on the loop for
proper supervision.
