SUPPLY AND INSTALLATION OF MOTION SENSORS IN PUMP ROOMS, MECHANICAL ROOMS, ROOF TOP & CAR PARKING

Site Survey & Design

• Conduct a detailed site survey to identify lighting layouts, lux requirements, and sensor locations.
• Develop a sensor placement design ensuring maximum coverage, minimal blind spots, and compliance with ASHRAE 90.1 energy efficiency standards.
• Submit design drawings and sensor specifications for consultant/client approval prior to execution.

 Supply of Motion Sensors

·       Supply high-quality PIR (Passive Infrared) and Microwave motion sensors with the following features:

o   Detection range suitable for corridors, rooms, and wide-area car parking.

o   Adjustable time delay and sensitivity settings.

o   Lux-level control to ensure lights operate only under low-light conditions.

o   Ceiling-mounted / wall-mounted / surface-mounted / flush-mounted type as per location requirements.

o   Ingress protection (IP) rating:

§  Minimum IP20 for indoor dry areas (corridors, rooms).

§  Minimum IP44 / IP65 for pump rooms, mechanical rooms, and car parking areas.

o   Impact resistance (IK rating) for exposed areas.

o   Compliance with Dubai Municipality and DEWA-approved manufacturer list.

o   Integration capability with LED lighting systems and existing electrical circuits.

 Installation Works

·       Install motion sensors at identified points across entrances, pump rooms, mechanical rooms, Roof top and car parking as per approved shop drawings.

·       Connect sensors to lighting circuits with fire-retardant, low-smoke zero-halogen (LSZH) cables in compliance with DEWA and NFPA 70 (NEC).

·       Mounting height, angle, and sensor orientation to follow manufacturer recommendations for maximum coverage.

·       Provide separate circuit isolation and protection (MCBs) for sensor-controlled circuits.

·       Integrate sensors with existing LED fixtures without affecting emergency lighting circuits.

·       Ensure all installation works comply with Dubai Municipality Electrical & Green Building Codes.

Testing & Commissioning

·       Test motion sensors for detection accuracy, time delay response, and lux-level adjustments.

·       Perform lux-level measurements at entrances, corridors, rooms, and car parking areas to confirm compliance with Dubai Green Building Regulations (Al Sa’fat) and CIBSE lighting guidelines.

·       Conduct functional testing in the presence of client/consultant.

·       Provide final testing & commissioning report including sensor locations, calibration settings, and performance results.

Documentation & Training

·       Submit as-built drawings showing all sensor locations, wiring, and connections.

·       Provide O&M manuals, sensor technical data sheets, and warranty certificates.

·       Deliver training to facility management staff on operation, adjustment, and troubleshooting of the motion sensor system.

Standards & Compliance

All works shall be executed in strict compliance with the following standards and codes:

·       Dubai Municipality (DM) Regulations

·       Dubai Green Building Regulations (Al Sa’fat)

·       Dubai Civil Defence (DCD) Fire & Life Safety Code of Practice

·       DEWA Regulations for electrical installations

·       ASHRAE 90.1 – Energy Standard for Buildings

·       CIBSE & IES Lighting Guidelines

·       IEC 60669-2-1 / BS EN 60669 – Motion sensor switches

·       NFPA 70 (NEC) – Electrical Safety Code

Handover Requirements

·       Submit completion certificate, warranties (minimum 2 years), and compliance approvals.

·       Provide final inspection and approval with the client/consultant.
