DMP 736P Radionics POPIT Interface Module
The DMP 736P is an interface module built to bridge an existing Radionics POPIT wiring infrastructure onto a DMP control panel's LX-Bus. If a site is running Radionics POPIT, POPEX, or OctoPOPIT modules and the control panel is being upgraded to a DMP XR Series panel, the 736P is what lets that field wiring stay in the wall instead of getting ripped out. It's a migration tool first and a zone expander second — the value is in what it lets you avoid re-pulling.
Overview
Panel swaps are rarely the hard part of a security upgrade — the wiring is. When a Radionics system reaches end of life and a customer wants to move to a DMP platform, the field devices, conduit runs, and POPIT hardware represent the real sunk cost. The 736P sits between that legacy wiring and the new panel's LX-Bus, translating the existing POPIT infrastructure so it keeps working under DMP control. That means the upgrade path to DMP security systems becomes a controller swap and a module install, not a rewire job — a meaningful difference in labor hours on any multi-zone commercial account.
Key Features
- Supervises up to 100 POPIT zones from the LX-Bus: a single 736P can carry a substantial legacy zone count forward onto the new panel, so larger Radionics installs don't need multiple interface points just to preserve coverage.
- Up to 32 zones on the keypad bus: in addition to LX-Bus zone supervision, the 736P extends zone capacity across the keypad bus — useful headroom when a site's zone count is split across bus types.
- Compatible with POPIT, POPEX, and OctoPOPIT modules: the 736P doesn't require you to standardize on one legacy module type before cutting over — mixed Radionics module deployments can be preserved as-is.
- 12 VDC operation: runs on standard low-voltage panel power, so it integrates into existing power budgeting without a dedicated supply.
- Cost-effective upgrade path to XR Series features: customers get DMP XR Series panel capabilities without the labor cost of abandoning and replacing existing field wiring — the module's entire reason to exist is protecting that installed base.
- Maintains existing wiring topology: because the 736P works with the wiring already in place, technicians don't need as-built drawings redone or new zone maps drafted from scratch.
Integration & Compatibility
The 736P is purpose-built for one migration path: Radionics POPIT-based systems moving to a DMP panel over the LX-Bus. It is not a general-purpose zone expander for native DMP installations — its value is specifically in preserving Radionics-era field hardware. Anyone quoting a Radionics-to-DMP conversion should treat the 736P as a required line item alongside the new panel itself, since without it the POPIT wiring becomes stranded. For panel selection guidance on the receiving end of this upgrade, see the security control panels category and a system planning guide before finalizing a bill of materials. Pair the panel upgrade with appropriate power supplies sized for the combined legacy and native zone load, and review DMP keypads if the keypad bus zone count is being expanded alongside the POPIT migration.

Frequently Asked Questions
Q: What does the DMP 736P actually do?
A: It interfaces an existing Radionics POPIT system to a DMP panel's LX-Bus, allowing existing POPIT, POPEX, and OctoPOPIT wiring to remain in place after a panel upgrade.
Q: How many zones does the 736P support?
A: It supervises up to 100 POPIT zones from the DMP LX-Bus, plus up to 32 zones on the keypad bus.
Q: What voltage does the 736P run on?
A: It operates at 12 VDC.
Q: Does the 736P work with OctoPOPIT modules, or only standard POPIT?
A: It supports existing POPIT, POPEX, and OctoPOPIT modules and wiring.
Q: Why would I need the 736P instead of just rewiring for a new DMP panel?
A: The 736P lets you keep existing Radionics field wiring in place during a panel upgrade, avoiding the labor cost of rewiring while still gaining DMP XR Series panel benefits.
The 736P earns its keep on Radionics-to-DMP conversion jobs specifically. I spec this when a customer has an aging Radionics POPIT system and wants to move to a DMP panel without eating the labor cost of pulling new zone wiring — the 736P sits on the LX-Bus and keeps that legacy field hardware talking to the new panel.
Technical Highlights:
- 100 POPIT zones from the LX-Bus: covers larger legacy installs off a single module, so you're not stacking interface hardware just to preserve zone count on a bigger commercial account.
- 32 zones on the keypad bus: gives you extra capacity split across bus types, which matters when a site's original POPIT zone map doesn't map cleanly to one bus.
- 12 VDC operation: standard panel-level voltage, no auxiliary power supply to budget for on the install.
Deployment Considerations:
- This module supports POPIT, POPEX, and OctoPOPIT wiring specifically — confirm which Radionics module types are actually on site before quoting, since mixed installs are common on older accounts.
- The 736P is a migration-specific part, not a general zone expander for new DMP installs — don't spec it unless you're actually carrying forward Radionics field wiring.
Right tool for a Radionics POPIT-to-DMP XR panel conversion where the customer wants to protect their existing wiring investment rather than fund a full rewire.
