Product Overview

The Bosch D9127 Series POPIT Modules, including the D9127T (with magnetic tamper switch) and the D9127U (without tamper), expand compatible control panels when additional initiating zones or points are required. Designed for use with D8125 or B299 Addressable Expansion Modules, they allow cost-effective system growth by supporting installation anywhere along a two-wire data expansion loop.

These modules combine zone and point supervision with individual device addressing over a single wire pair for efficient monitoring. Screw terminals ensure secure and reliable wiring for both the data expansion loop and the supervised sensor loop. A 33 kΩ end-of-line resistor installed at the farthest point of the loop provides proper supervision. Their compact size allows flexible installation in standard outlet boxes, above suspended ceilings, closets, or other accessible locations.
