LiftMaster Pneumatic 22' Sensing Edge with 2-Wire Coil Cord | LIF-658302

LiftMaster Pneumatic 22' Sensing Edge with 2-Wire Coil Cord | LIF-658302

Pneumatic edge kit with exterior air switch. For additional hose, add $1.50 per foot.

A sensing edge should be used on every door for the protection of pedestrians and vehicles. Depending on the type of edge and type of control wiring of the operator with which it is used, the function of the edge will vary.

Standard Edge:
A standard 2-wire edge will cause a door to reverse when it meets an obstruction while closing if the operator has type B2, C2, S2, T, T1 or TS control wiring.

Failsafe Edge:
A failsafe edge (or self-monitoring edge) requires either a 3- or 4-wire connection and will not only cause a door to reverse while closing but will also render the door inoperable if the edge is not installed or if it becomes damaged after installation. A failsafe electric edge requires an operator with type F2 wiring or the use of a CPS II™ option board. The infrared link-edge is inherently failsafe and requires only type B2, C2, S2, T, T1 or TS control wiring.

Includes

• 2-wire coil cord
• 22 feet of air hose

Notes

1. Specify the length of the edge when ordering.
2. For electrical edges, the length equals daylight opening minus 2 inches. Minimum length - 5ft.
3. A coil cord or take-up reel is required with all edges. Some failsafe applications may require a 3 or 4-wire cord.
4. Take-up reels are not recommended for use with any failsafe type edge. Use coil cords only.
5. If the door is over 22 feet wide, electric edges or photo eyes are highly recommended.

Warning: It is strongly recommended that some type of safety equipment be used with every door operator. Without safety equipment, serious injury or death may result!
