Motion sensor Grothe McGuard PM-APws Presence White – model 94500, presence detector, white finish

Grothe McGuard PM-APws Presence White (model 94500) is a wall-mounted presence detector in a white finish designed for indoor lighting and security control. The device senses motion and presence to trigger automated switching, integrate with building control systems and help reduce energy consumption. It is suitable for corridors, offices, stairwells and other indoor areas where reliable presence detection is required.

Advantages

The presence detector provides dependable detection of both transient movement and sustained presence, enabling automatic control of lighting and ventilation circuits. Its discreet white housing blends into many interior designs while offering durable construction for regular indoor use. Integration capability with building automation systems allows flexible configuration and centralized control, and the sensor’s sensitivity and detection range support efficient energy management.

Suitable for

• Office open-plan areas and meeting rooms
• Corridors and stairwells
• Storage rooms and utility areas
• Entrances, lobbies and common areas

Key specifications

• Mounting: wall-mounted presence/motion sensor for indoor installation
• Finish: white housing designed to match interior fixtures
• Detection: designed to detect movement and presence for automated switching
• Integration: compatible with building control systems for automated lighting and security control
• Application: intended for general indoor environments such as corridors, offices and staircases

How to use

Install the Grothe McGuard PM-APws on a wall at the recommended mounting height for the target area and connect it to the building control or lighting circuit according to local electrical regulations and wiring schematics. Configure detection sensitivity, time delay and integration settings through the control interface or during commissioning to match occupancy patterns. After installation and configuration, the sensor automatically switches lighting or control circuits when presence or movement is detected and returns to standby or off state after the configured absence time.

Usage recommendations

Position the sensor to avoid direct exposure to ventilation outlets, large heat sources or glass surfaces that may cause false triggers. Perform commissioning tests under typical occupancy conditions to set sensitivity and time delay correctly. For optimal energy savings combine presence detection with daylight-linked control and appropriate time settings in the building control logic.
