Morris 80540 PIR Occupancy/Vacancy Wall Sensor, Single-Pole / 3-Way, 3-Way, White

Product Overview

The Morris 80540 is a white passive infrared (PIR) occupancy/vacancy wall sensor for single‑pole or 3‑way lighting control. It detects motion by sensing differences in infrared energy and supports Auto ON/Auto OFF and Manual ON/Auto OFF (vacancy) modes.

The sensor provides adjustable ambient light‑level sensitivity, an adjustable time delay from 5 seconds to 30 minutes, a 180° coverage pattern, and requires a neutral connection. A decorative wall plate is included.

Function and Modes

The 80540 uses a passive infrared sensor to detect motion by sensing differences in infrared energy emitted by people versus the ambient environment. It supports Auto ON/Auto OFF for fully automatic operation and Manual ON/Auto OFF (vacancy) where the occupant turns lights on manually and the sensor turns them off after the set time delay.

• Auto ON/Auto OFF: automatic switching based on detected occupancy.
• Manual ON/Auto OFF (Vacancy): manual ON; automatic OFF after the time delay setting.

Coverage, Range and Timing

The sensor provides a 180° detection pattern suitable for wall mounting. The product listing specifies a range of up to 30 ft when mounted at a 4 ft height. Time delay off is adjustable between 5 seconds and 30 minutes.

• Coverage angle: 180°
• Stated range: up to 30 ft when mounted at 4 ft
• Time delay off: adjustable from 5 seconds to 30 minutes

Electrical Ratings and Load Compatibility

Verify the sensor's voltage and load ratings match your circuit and fixtures. The 80540 is rated for a wide voltage range and the listing identifies several lamp types as compatible.

• Operating voltage: 120–277V
• Load rating: 800W at 120V; 1200W at 277V
• Neutral conductor: required
• Listed compatible lamp types: incandescent; electronic-ballast fluorescent; CFL; magnetic low-voltage; electronic low-voltage; LED

Installation and Controls

The 80540 is installed as a replacement for a standard wall switch. The product listing indicates the removable cover reveals mode and dip-switch settings for sensitivity and timing adjustments, and a decorative wall plate is included.

• Replace existing wall switch and connect line, load, neutral, and ground as applicable
• Removable cover exposes mode selection and dip switches for configuration
• LED indicator for visibility in darkened rooms
• Decorative wall plate included

Recommended Applications

The product listing notes typical indoor uses and mentions California Title 24 compliance.

• Typical uses listed: offices, conference rooms, restrooms, and similar occupied indoor spaces
• Conforms to California Title 24 energy code (per product listing)

Before You Order

Verify that a neutral conductor is available in the switch box and that the sensor's voltage and load ratings match your circuit and fixtures.

• Neutral must be present in the switch box—required for operation.
• Confirm the combined connected load does not exceed the sensor's ratings (800W@120V / 1200W@277V).
• For 3-way installations, ensure the wiring configuration is suitable for a single-pole/3-way sensor replacement.
