D9127T BOSCH

Product Overview

The Bosch D9127 Series POPIT Modules, including the D9127T (with magnetic tamper switch) and D9127U (without tamper), are designed to expand compatible control panels when additional initiating zones or points are required. Used with addressable expansion modules, these POPIT devices allow economical system growth by being installed anywhere along a two-wire data expansion loop.

The modules combine zone and point supervision with individual device addressing over a single wire pair, ensuring reliable monitoring and communication. Screw terminal connections provide secure wiring for both the data expansion loop and supervised sensor loop. For proper supervision, a 33 kΩ end-of-line resistor is installed at the farthest point on the loop. Their compact design allows flexible installation in standard outlet boxes, above suspended ceilings, closets, or other accessible locations.
