The Ex-Or MR1500P / MR1500PF Mid Range LightSpot is a highly sensitive movement detector designed for lighting control, primarily in commercial and industrial settings. It utilizes microwave technology to detect occupancy and is suitable for switching loads up to 10 Amps. The device is available in two versions: MR1500P for surface mounting and MR1500PF for semi-flush mounting.

Function Description:

The primary function of the Mid Range LightSpot is to automatically control lighting based on occupancy detection and ambient light levels. It can operate in a "Volt-Free" mode, providing contacts for external switching, or a "Live-Out" mode, directly switching a connected load. The detector incorporates a photocell for daylight harvesting, allowing it to hold off or extinguish lighting when sufficient natural light is available, thereby saving energy.

Occupancy Detection:

The device employs microwave technology for presence detection. This technology allows for detection through certain materials like plasterboard, wood, and glass, which means careful positioning is crucial to avoid unwanted detection through partitions. However, it is not recommended for applications with large areas of metal (e.g., metal ceilings or panelling) as this can lead to unpredictable sensitivity. The detector's sensitivity to movement can be adjusted for both when lights are ON ("ON Sensitivity") and when lights are OFF ("OFF Sensitivity"). These settings allow for fine-tuning the detection range to suit specific application requirements.

Photocell Control:

The integrated photocell offers two main modes: ACTIVE and PASSIVE, in addition to a DISABLED option.

• ACTIVE Mode: In this mode, the photocell holds off lighting on entry if natural light exceeds a "SET-POINT LOW" threshold. Crucially, it will also extinguish lighting during occupancy if natural light increases sufficiently and continuously for a period equal to the "OFF DELAY," exceeding a "SET-POINT HIGH" threshold. Lighting is restored if illumination drops below "SET-POINT LOW."
• PASSIVE Mode: Similar to ACTIVE mode, it holds off lighting on entry if natural light exceeds "SET-POINT LOW." However, in PASSIVE mode, the photocell will not extinguish lighting during occupancy if natural light increases. It only prevents lights from coming on if there's already enough natural light.
• DISABLED Mode: When disabled, the photocell has no effect on the controlled load, which will remain ON continuously during occupancy unless manually switched OFF.

The photocell's "SET-POINT LOW" and "SET-POINT HIGH" thresholds can be programmed manually using numerical values (1 to 1023, representing darkest to brightest) or by a "Teaching the Levels" method. This teaching method involves setting the desired natural light level and then using the QuickSet Pro tool to automatically record the appropriate high and low set-points, ensuring optimal hysteresis to prevent light oscillation.

Time Delay:

The detector features an adjustable "Off Delay" ranging from 1 minute to 96 hours, with a special 10-second walk-test mode available for commissioning. This delay determines how long the lights remain on after the last detected movement.

Installation and Commissioning:

Installation should only be carried out by suitably qualified personnel. The detector must be installed on a rigid surface free from movement or vibration. Ideal mounting locations are typically in a corner, by an entrance, or at one end of a corridor, at a height of 2.5 to 3.5m. It should not be mounted within 25cm of a fluorescent fitting. For ceiling mounting, a 76mm hole is required for the semi-flush version. A Wall-mounting Kit (WMK) is available for horizontal or vertical wall installations, particularly useful for racking aisle applications.

Commissioning requires the use of a QuickSet Pro infrared programming tool to adjust programmable parameters such as sensitivity, off delay, and photocell settings. The units are supplied with factory default settings, which may be sufficient for many applications, but customisation is possible.

Important Additional Notes:

• The product is not intended to be used as a junction box for looping cables; all terminals are for final connections.
• Due to microwave technology, the device can detect large moving metal objects beyond its normal human detection range, so careful location selection is important.
• The device switches lights no more frequently than a human occupant would. However, users should check with luminaire manufacturers regarding compatibility with automatic controls and any specified maximum switching cycles to ensure predicted lamp life.

Important Technical Specifications:

• Operating Voltage: 230V ~ 50Hz (UK & Europe)
• Switch Capacity: 10 Amps max for any lighting load, except incandescent lamps (1500W max at 230V~)
• Maximum Recommended Mounting Height: 3.5m
• Range: Adjustable up to 20m
• Off Delay: 1 min - 96 hours, plus 10-second walk-test mode
• Photocell: Passive/Active/Disabled, adjustable 50-5000 lux
• Material: Flame retardant PC/ABS
• Colour: White
• Weight: 180g (semi-flush version), 160g (surface version)
• IP Rating: 4X
• Operating Temperature: 0°C to 40°C

Usage Features:

• Energy Saving: Automatic lighting control based on occupancy and daylight harvesting significantly reduces energy consumption.
• Programmable Settings: All parameters, including sensitivity, off delay, and photocell set-points, are programmable via the QuickSet Pro tool, allowing for tailored performance.
• Retained Settings: Programmable parameters are retained even in the event of a power failure.
• Flexible Mounting: Available for surface or semi-flush ceiling mounting, with an optional wall-mounting kit for specific applications.
• Parallel Connection: Multiple MR1500Ps' relay outputs can be connected in parallel, provided the total controlled load does not exceed 10 Amps.

Maintenance Features:

• No specific routine maintenance is described in the provided manual.
• The device is designed for long-term operation with robust materials (flame retardant PC/ABS).
• End-of-life disposal should follow recycling guidelines for packaging and product, avoiding normal household waste and burning.
