Interlock Switch For Sectional Door IS2

IS2 Sectional Garage Door Interlock Switch – Operator Lockout Safety Switch

The IS2 Interlock Switch is designed for commercial sectional garage doors equipped with an electric operator and mechanical door lock.

When the sectional door is manually locked, the interlock switch interrupts the operator control circuit and prevents the electric operator from attempting to open the locked door. This helps protect the operator, door hardware, lock assembly, and drive components from damage caused by accidental motor operation while the door is secured.

The compact switch mounts on the interior door track using the supplied bracket and is designed specifically for sectional overhead door applications.

How It Works

A commercial sectional door may be equipped with a manual slide lock or other mechanical locking device.

If the electric operator is activated while that lock is engaged, the motor may attempt to move a door that physically cannot open. This can place significant stress on:

• The commercial door operator

• Drive chains and sprockets

• Door sections

• Track hardware

• Lock assemblies

• Shafts and related components

The IS2 interlock switch is installed so that engagement of the mechanical door lock changes the interlock circuit and disables operator operation while the door remains locked.

Once the mechanical lock is released, the operator control circuit can return to normal operation.

Common Applications

Suitable for:

• Commercial sectional garage doors

• Industrial sectional overhead doors

• Warehouse doors

• Loading dock doors

• Service facility doors

• Commercial buildings with manually lockable powered doors

• Sectional doors using compatible jackshaft or commercial operators

Why Use an Interlock Switch?

Mechanical door locks and electric operators should not operate independently without protection.

An interlock switch provides a simple safeguard against accidentally powering the operator while the door is mechanically secured, helping prevent unnecessary equipment damage and service calls.

Compatibility

Designed specifically for sectional overhead doors.

Before ordering, verify:

• The door uses a compatible mechanical locking system

• The operator provides a compatible interlock/control circuit

• Track configuration allows proper switch mounting

• Installation location permits the lock to properly actuate the switch

Do not confuse this sectional-door interlock with interlock switches designed for rolling steel doors or pass-door applications.

Operator, door lock, control wiring, conduit, and other installation components are sold separately.

Important Installation Note

The interlock switch must be wired into the appropriate operator control circuit according to the operator manufacturer's instructions.

After installation, test the system and verify that the electric operator cannot activate while the sectional door is mechanically locked.

Installation should be performed by a qualified commercial door technician.
