Installation and Mounting Guide for KTI17001002PEM4 LED Emergency Exit Light

Proper installation of the KTI17001002PEM4 LED Emergency Exit Light ensures structural stability, compliance with IS 10322 illumination safety standards, and reliable operation during emergency power interruptions. Designed for commercial, institutional, and industrial facilities, this 600 mm x 300 mm luminaire provides directional guidance across critical egress routes.

Pre-Installation Site Assessment

Before proceeding with mechanical installation, verify that the intended mounting location complies with the environmental and electrical parameters of the unit. The KTI17001002PEM4 carries an IP20 ingress protection rating, making it suitable for clean, dry indoor environments such as staircases, hotel corridors, commercial showrooms, battery rooms, shopping malls, and covered underground parking facilities.

• Confirm clear line-of-sight visibility along exit pathways and egress access doors.
• Verify that the structural surface (masonry, drywall framing, or ceiling grid) can securely support the unit net weight of 1.3 kg.
• Ensure an unswitched ~230 V AC (50 Hz ±10%) power feed is routed to the junction location for continuous battery charging.

Mechanical Wall and Ceiling Mounting Procedures

The unit features a precision-engineered housing made of uniformly extruded aluminium alloy finished with a white epoxy polyester powder coating. The rear chassis includes two integrated keyhole mounting slots configured for either vertical wall placement or overhead ceiling mounting.

1. Marking Slot Locations: Align the fixture against the mounting plane at the designated height. Mark the drill positions corresponding precisely to the 2 keyhole mounting slots on the extruded aluminium housing.
2. Anchoring: Drill pilot holes into the wall or ceiling substrate and insert heavy-duty wall plugs or anchors rated for structural fixtures. Fasten mounting screws into the anchors, leaving screw heads projecting slightly to engage the keyhole slots.
3. Fixture Alignment: Align the mounting slots of the emergency light over the screw heads, push the fixture flush against the mounting surface, and slide it down/forward into the locked keyhole position. Ensure the 6 mm clear acrylic CAD-designed message diffuser panel remains clean and unobstructed.

Electrical Connections and Mains Interface

Electrical connections must be performed by certified electrical personnel in accordance with national electrical codes and IS 10322 standards. The luminaire features an electrical-grade, 5 A, 250 V PCB mount connector integrated inside the enclosure.

Connect the primary supply lines directly to the 5 A, 250 V PCB mount terminal block, observing proper phase and neutral polarity. The internal circuitry is calibrated for ~230 V AC, 50 Hz (±10%) mains input. Ensure all conductors are firmly clamped and insulated to prevent short circuits against the aluminium housing.

Initial Commissioning and Charging Cycle

Once mechanical and electrical connections are verified, energize the AC mains circuit to initiate the commissioning process:

• Continuous Powering: Upon energization, the internal constant current charger activates to charge the integrated Lithium-ion rechargeable battery.
• Full Charge Cycle: Allow an initial uninterrupted recharging period of 16 to 24 hours to achieve full battery capacity.
• Emergency Operation Test: Disconnect AC mains power to verify automatic switchover. The internal Lithium-ion battery must immediately illuminate the multiple LEDs, providing rated backup illumination for up to 180 minutes (±10%).
