Somfy Simu T8S DMI 200 Nm 94mm Slim Head Motor Specs

Heavy rolling shutters and coiling grilles need a tubular operator sized to the barrel, not to the opening. The Somfy Simu T8S DMI 200 Nm Diameter 94mm 120V Slim Head (2008302) covers the 94mm barrel class with 200 Nm of torque and a manual override head. This guide walks the fitment and the control path an installer settles before ordering.

Tube diameter and torque set this spec

Specifiers reach this reference by working backward from the barrel. The motor runs inside a 94mm tube and turns it at 10 rpm, holding 200 Nm against the weight of the curtain. Measure the barrel first. A 94mm barrel takes this reference. Somfy builds an adjustable 99 to 108mm version for larger tubes, and a 280 Nm head for heavier curtains on the same 94mm class.

Torque headroom matters on a coiling door. Installers size the operator above the static load so the motor starts the curtain from rest without stalling on a cold morning. Somfy rates the T8S DMI for 10 cycles per day, which suits a loading dock, a storefront grille or a warehouse bay that opens and closes through a shift.

Closures this operator suits

Somfy lists the T8S DMI for industrial and commercial closures and for rolling shutters. The slim head keeps the motor profile tight inside a hood or a side-plate box, which helps on a retrofit where the headroom was set by the original hand-chain gear. Shop fronts, parking structures, service counters and fire-station bays all sit inside the duty Somfy publishes for this reference.

Residential shade work does not call for this platform. A 200 Nm operator belongs on a barrel carrying a slatted aluminum or steel curtain, and the smaller Simu T5 and T6 families cover awnings and domestic shutters. Pick the T8S DMI once the curtain weight pushes past what a T6 holds.

Verified specs

Two figures here decide most orders. The 600 W draw tells the electrician what the circuit and the relay have to carry, and the 0 W standby figure keeps a bank of these operators off a building's idle load. Somfy backs the reference with a 5-year warranty.

The DMI head and outage operation

DMI marks the manual override head. A power cut on a coiling grille locks the opening, and a building needs a way to raise that curtain by hand. Somfy answers it with two parts for this head. The chain hoist (9019458) bolts to the override drive and takes a hand chain, which Somfy supplies as a separate reference (9019460). For a crank release instead, Somfy lists an eye and hex shaft, 7 mm by 400 mm (9018569).

Specify the override hardware with the motor. The head accepts one or the other, and the choice follows the opening. A tall warehouse door suits the chain hoist, since an operator works it from floor level. A service counter shutter at head height suits the shorter crank shaft. Order the chain alongside the hoist so the install crew does not stop halfway.

Drives, inserts and brackets

The motor transmits torque through a round drive matched to the barrel. Somfy lists the T8 94mm Round Drive for 200 Nm to 280 Nm (9001297) against this reference, with a 97mm round set (9001312) and a 124mm round set (9013824) for the larger barrels in the family. Pair the drive with the idle insert that matches the tube, which Somfy publishes as a 94mm insert (9542008) on this diameter.

Mounting runs through the T8-S / T8-S DMI Operator Bracket (9018069), the plate Somfy names for this head style. Somfy also publishes 280x280 and 330x330 side wall plates for T6, T8 and T9 operators, which carry the motor and the idler inside a boxed hood.

Safety brakes belong in the same order on a heavy closure. Somfy lists six ratings against this motor, and two sit at the volumes most buildings need.

The Simu Safety Brake 404 Nm (2005627) covers a 200 Nm operator with margin on a standard commercial curtain. The Simu Safety Brake M10A 1000 Nm (2005629) steps up for the heaviest barrels, and Somfy lists it across the T8, T8M, T8S, T8S DMI and T9 range. Match the brake to the barrel load your engineer calculates, then mount it on the opposite end of the tube from the motor.

Wiring and control

The T8S DMI takes 4-wire control on 120V/60Hz. Two of the conductors drive the two directions, with a neutral and a ground. Wire it to a maintained key switch, a momentary three-position switch or a relay module on a building control panel. Somfy rates the motor Class I, so the ground connection is part of the install, not an option.

Limits set at the head. A technician drives the curtain to each end and sets the stop, then cycles the closure to confirm the slat sits in the guide at the top and seals at the sill. Keep the 4 minute thermal time in mind during commissioning. Running a long door up and down a dozen times in a row trips the internal protection, and the motor restarts once it cools.

Bench testing saves a trip up the ladder. The Somfy Standard Motor Tester Cable, 4-Wire (9012116) lets a technician confirm rotation and limits before the motor goes into the barrel.

Order the Simu T8S DMI 200 Nm Diameter 94mm 120V Slim Head (2008302) with the drive, the insert and the operator bracket that match your barrel, and add the safety brake your load calculation calls for. Buyers who need the same torque on a 99 to 108mm barrel should look at the adjustable version, and buyers carrying a heavier curtain on a 94mm tube should look at the 280 Nm head.

Common questions

What tube does the Simu T8S DMI 200 Nm fit?

Somfy builds this reference for a 94mm barrel. The motor seats inside the tube and drives it through a T8 94mm round drive rated for 200 Nm to 280 Nm. For a 99 to 108mm barrel, Somfy publishes an adjustable version of the same 200 Nm operator.

How does the DMI manual override work?

The DMI head carries a manual drive for power outages. Somfy lists a chain hoist (9019458) with a separate hand chain (9019460), and an eye and hex shaft, 7 mm by 400 mm (9018569), for crank operation. Specify one of the two with the motor.

Does the T8S DMI need a safety brake?

Heavy rolling closures carry a fall risk, and a rated brake on the barrel answers it. Somfy lists brakes from 258 Nm through 3000 Nm against this motor. The 404 Nm brake (2005627) suits a standard commercial curtain, and the 1000 Nm brake (2005629) covers heavier barrels.

Which switch controls this motor?

The motor takes 4-wire wired control on 120V/60Hz. A maintained key switch, a momentary three-position switch or a relay on a building panel all drive it. Somfy rates the motor Class I, so the install needs a ground connection at the motor.
