Description: Here are the following modules all in working order (6) D9127U (2) D9127T (Tamper cover) (1) D928 phone line switcher (1) D8125 Zone expansion module Note; will need the 33k EOL resistors for 6 of the modules, (only the (2) D9127T have EOL D8125 information System overview Certifications and approvals Intrusion Alarm Systems | D8125 Expansion module D8125 Expansion module www.boschsecurity.com 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. 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 D9127U information The D9127 Series POPIT Modules includes the D9127T (with magnetic tamper switch) and the D9127U (without tamper). They are used with a D8125 or B299 Addressable Expansion Module when there is a need to expand a compatible control panel beyond its standard number of on-board initiating zones or points. Future system expansion is very economical as D9127 Series POPITs can be added anywhere along the two-wire data expansion loop from the D8125 or B299 modules. Both modules include proven technology that combines zone and point supervision with individual device addressing on one pair of wires. Screw terminals provide reliable connections for the data expansion loop and supervised sensor loop wiring. Install a 33 kΩ end-of-line resistor at the farthest point on the loop for proper supervision. The units are small and easily installed in standard outlet boxes, above false ceilings, closets, or other accessible locations.
