Mechanical Mounting and Enclosure Placement
The Prolite PEL LED TBL (SQ) WP(1) emergency light features a versatile structural design engineered for either permanent surface wall installation or portable deployment in industrial and commercial environments. For fixed surface installations, the rear housing includes a dedicated four-point wall mounting pattern configured with an exact center-to-center pitch of 180 mm horizontally and 160 mm vertically. Installers must align structural wall anchors to this 180 mm by 160 mm layout to guarantee rigid support for the complete luminaire assembly, which has a physical weight of approximately 4 kg.
Physical dimensions of the Polycarbonate main body measure 355 mm in width, 255 mm in overall height, and 122 mm in depth (with an allowable manufacturing tolerance of ±5 mm). When planning wall placement, provide adequate spatial clearance around the unit to facilitate access to the dual 10 W LED lamp heads. These twin aluminium diecast enclosures are finished in White epoxy polyester powder coating with clear glass diffusers and require unobstructed clearance for beam direction across targeted egress pathways.
Electrical Connections and Supply Wiring
Electrical integration must be completed using the integrated electrical grade mains connector, rated for 5 A at 250 V. Standard operation requires connection to an alternating current supply line rated at ~230 V AC, 50 Hz (±10%). Alternative factory-configured input voltages are supported upon custom order under Price On Request (POR) terms. Field personnel must ensure incoming mains supply conductors are properly isolated prior to terminating into the 5 A, 250 V electrical grade connector block.
The internal driver circuitry operates in Non-Maintained mode, meaning the twin 10 W LED arrays remain unlit while the continuous ~230 V AC supply is active. The internal circuitry continuously senses mains line integrity. Upon sudden utility power interruption, the internal contactors transfer load to the SLA rechargeable battery (they are not included) to illuminate the two 10 W LED modules (featuring GMR Light, BridgeLux, Edison, or Lustrous LED chips) for a full emergency rating of 180 minutes (+10%).
Commissioning and Charging Procedures
Following mechanical fixing and mains termination, energize the AC supply circuit to begin the initial battery (they are not included) charge cycle. The built-in constant voltage charger requires a continuous recharging period of 10 to 12 hours to bring the internal SLA battery (they are not included) system to nominal charge. The internal electronics incorporate a low-voltage automatic cut-off mechanism that disconnects the load to protect the power storage cells from deep discharge during prolonged blackouts. Once the utility supply resumes, quick recharge initiates automatically, seamlessly transitioning into a continuous trickle charge once the battery (they are not included) is fully replenished.
Environmental and Location Considerations
Certified to IS 10322 standards with an IP 65 ingress protection rating, the Grey RAL 7035 Polycarbonate housing is engineered for hostile and outdoor-exposed settings. Suitable installation sites include:
- Industrial warehouses, godowns, and logistics distribution hubs
- Underground parking structures and transit stairwells
- Battery (they are not included) rooms and electrical distribution substations
- Hotel corridors, commercial facilities, and railway yards
