Miller Edge SM-101 Signature Module – For Diode Capacitor (T3) Edges
The SM-101 Signature Module sits between a monitored sensing edge and a UL 325 compliant commercial door operator, converting the edge output into the pulsed signal some operators require. Without it, a compatible edge on one of those operators will read as a fault.
The SM-101 converts a diode capacitor (T3) edge. LED indicators show power and fault status, and a standard junction box is included.
Which module do you need?
It depends on the designator of your sensing edge, which in turn depends on your operator brand:
SM-101 — this product. For T3 diode capacitor edges. Used with Overhead Door and Genie operators.
SM-102 — for T2 10K resistive edges. Used with Linear, LiftMaster/Chamberlain, Manaras, Marantec, Micanan, Raynor and VE Power Door operators.
Not sure which designator your edge is? See the designator guide, or call (866) 965-5599.
Operator Compatibility
| Edge Designator | Module Required | Operator Brands |
|---|---|---|
| T3 — diode capacitor, red band | SM-101 (this product) | Overhead Door, Genie |
| T2 — 10K resistor, blue band | SM-102 | Linear, LiftMaster / Chamberlain, Manaras, Marantec, Micanan, Raynor, VE Power Door |
Cookson, Cornell / US Gear and Lawrence operators take a T2 edge without a module.

What's Included
- SM-101 Signature Module
- Standard 2″ × 4″ junction box
- (2) clamp-on style wire fittings
- (4) wire nuts
Completing the Installation
The junction box is designed to work with a coil cord or retracting reel carrying the edge lead from the moving door leaf:
- C182-20B coil cord — 18 gauge, 2 wire, stretches to 20 ft
- RR182-20M retracting reel — 18 gauge, 2 wire, 20 ft, metal enclosure

Important: Confirm the designator of your sensing edge and your operator's requirements before ordering. Fitting the wrong signature module will leave the operator reading a fault.
