### What Is It Used For?

- Homeowners
- Family members
- Children
- Temporary visitors
- Contractors
- Service personnel
- Replacement of an older LiftMaster keypad

### Broad LiftMaster Compatibility

One of the biggest advantages of the 878MAX is its compatibility with multiple generations of LiftMaster garage door opener technology.

LiftMaster lists compatibility with:

Green Learn Button
- Billion Code
- 390 MHz

Red / Orange Learn Button
- Security+
- 390 MHz

Purple Learn Button
- Security+
- 315 MHz

Yellow Learn Button
- Security+ 2.0

This makes the 878MAX much more versatile than keypads designed only for one specific Learn-button generation.

### Compatible With LiftMaster Openers Since 1993

For residential applications, the 878MAX is designed for compatible LiftMaster garage door openers manufactured on or after January 1, 1993 and equipped with a Learn button.

Residential openers must also have functioning photoelectric safety sensors located near the bottom of the garage door tracks.

Always verify the Learn-button color and opener configuration before ordering.

### Temporary PIN Access

The 878MAX can be programmed with a temporary 4-digit PIN.

Temporary access can be configured for:

- A specific number of hours
or
- A specific number of garage door openings

This is useful when temporary access is needed for visitors, contractors, delivery personnel, or service technicians without giving them the primary household PIN.

### Wireless Installation

The keypad communicates directly with the garage door opener by radio signal.

No low-voltage control wire needs to be run from the keypad to the opener.

Installation generally involves:

1. Installing the battery
2. Programming the keypad to the opener
3. Selecting a personal 4-digit PIN
4. Mounting the keypad outside the garage
5. Testing operation

### Installation Location

LiftMaster specifies that the keypad should be installed:

- Within sight of the garage door
- At least 5 feet above the ground
- Out of reach of small children
- Away from moving garage door components

### Compatibility Check

Before ordering, locate the Learn button on the garage door opener.

Compatible Learn-button colors include:

- Green
- Red / Orange
- Purple
- Yellow

If your opener does not have a compatible Learn button, verify compatibility before purchasing.

### 878MAX vs. 877LM

The 878MAX should not be confused with the LiftMaster 877LM.

The 877LM is primarily intended for Security+ 2.0 openers with a Yellow Learn button.

The 878MAX supports a much broader range of older and newer LiftMaster opener technologies.

### Package Contents

Includes:

- 1 – LiftMaster 878MAX Wireless Keyless Entry Keypad
- 1 – 9V Battery
- Mounting Hardware
- Programming / Installation Instructions

Garage door opener and other accessories are not included.

### Important Safety Information

Install the keypad where the garage door can be clearly seen during operation and at least 5 feet above the floor to keep it out of reach of children.

Only activate the garage door when the opening is clear of people, pets, vehicles, and objects.

For residential use, the opener must have properly functioning photoelectric safety sensors and automatic reversing equipment.

After programming, test the keypad and all garage door safety systems before normal use.
