Lamps & Indicators

Hazardous Area Signalling: Lamps & Indicators

Clear, reliable signalling is essential for maintaining safety in hazardous areas. Whether it’s a warning beacon, an indicator on a control panel, or a tower light guiding safe operations, these devices provide the immediate visual cues that keep personnel and equipment protected.

At Exloc Instruments UK, we supply ATEX certified lamps and indicators specifically designed for use in explosive atmospheres. Built to withstand tough industrial environments, they combine high visibility with long service life and low maintenance requirements.

From compact panel lamps for localised indication, to multi-stage signal towers for process control and safety alerts, our portfolio ensures that you have the right solution for every zone and every task.

LR4-EX Explosion Proof Signal Towers

The LR4-EX signal tower provides reliable, high-visibility status indication in hazardous areas, making it ideal for use in Zone 2 gas and Zone 22 dust environments. Built by adapting Patlite’s trusted LR4 stack tower for explosion-proof applications, the LR4-EX combines robust construction with clear multi-status signalling.

A double-reflection lens system ensures even 360° light output, while polycarbonate housing and silicone O-rings deliver durability in harsh industrial conditions. With options for visual and audible alerts, the LR4-EX helps operators quickly identify process changes and maintain safe operations.

Key features:

• ATEX compliant for Zone 2 (gas) and Zone 22 (dust) hazardous areas

• Uniform 360° light-emitting design for clear visibility

• Configurable with 1–5 tiers (40 mm diameter)

• Available in flashing or non-flashing modes

• Integrated sound module with four selectable alarm tones

• IP65 ingress protection for outdoor and washdown environments

• 24V DC rated voltage

• Flexible mounting, including wall-mount options

LR6-EX Explosion Proof Signal Towers

The LR6-EX signal tower delivers powerful, multi-status indication for hazardous areas where safety and compliance are critical. Designed for Zone 2 gas and Zone 22 dust environments, it adapts Patlite’s proven LR6 stack tower for explosion-proof use, combining high visibility with rugged reliability.

Featuring a double-reflection lens system and vertical/horizontal cut lenses, the LR6-EX provides a uniform 360° light output that ensures clear signalling across wide industrial spaces. A reinforced polycarbonate housing with silicone O-rings protects against harsh conditions, while integrated sound modules offer both visual and audible alerts.

Key features:

• ATEX compliant for Zone 2 (gas) and Zone 22 (dust) hazardous areas

• Larger 60 mm diameter tower for improved visibility at distance

• Configurable with 1–5 tiers for multi-status indication

• Flashing or non-flashing light options

• Built-in sound module with four selectable alarm tones

• IP65 ingress protection for outdoor and washdown use

• 24V DC rated voltage

• Sturdy polycarbonate body with silicone O-rings for long service life

• Flexible wall-mount installation

BA390 Intrinsically Safe LED Panel Lamps

The BA390 series provides dependable visual indication for use in hazardous areas, combining low-power consumption with outstanding reliability. Designed for intrinsically safe installations, these compact LED panel lamps are approved to ATEX, IECEx, and FM standards, eliminating the need for bulky explosion-proof housings.

With bright, uniform light output and a choice of five colours, the BA390 is ideal for control panels, operator stations, and enclosures where long-life, low-maintenance signalling is essential. A special “S” version is available for fieldbus applications, offering ultra-low 4 mA current consumption.

Key features:

• Intrinsically safe design (ATEX, IECEx, FM approved)

• Bright LED illumination with coloured diffuser for uniform output

• 10+ year continuous life expectancy

• Low 20 mA standard current consumption

• Super-low 4 mA “S” versions for fieldbus compatibility

• IP65 environmental rating for harsh conditions

• Easy panel mounting with wide barrier compatibility

• No explosion-proof housing required

Installation tip: For cost-effective multi-channel setups, pair BA390 lamps with the D1041Q Intrinsically Safe Isolator for simplified, economical installation.

Applications & Industries

Hazardous area lamps and indicators are a cornerstone of safe operations across a wide range of industries. By providing clear visual and audible alerts, they ensure operators can respond quickly to changing conditions, even in the most demanding environments. Whether it’s a compact intrinsically safe LED panel lamp on a control system or a multi-tier explosion proof signal tower on the plant floor, these devices improve safety, compliance, and operational efficiency.

Oil & Gas

On offshore platforms, refineries, and gas processing sites, operators rely on ATEX certified signal towers to indicate process status, equipment faults, and emergency conditions. LED panel lamps provide local indication on control cabinets, while rugged LED clusters offer long-life performance in exposed environments with extreme temperatures, vibration, and corrosive atmospheres.

Chemical & Petrochemical

In chemical plants and storage facilities, hazardous gases and vapours create an ever-present ignition risk. Explosion proof signal towers and intrinsically safe lamps give workers instant visual confirmation of process states, alarms, or safe shutdown conditions. This reduces the chance of miscommunication and helps sites maintain compliance with strict international safety standards.

Pharmaceutical & Life Sciences

Pharmaceutical production often involves dust and volatile solvents. Zone 2 and Zone 22 signalling devices are critical for protecting staff and maintaining cleanroom integrity. The BA390 intrinsically safe LED panel lamps offer low-power consumption and long service life, ideal for installations where continuous uptime and reliability are non-negotiable.

Food & Beverage

Powder handling and dust hazards in food processing facilities require reliable hazardous area indicators. From monitoring conveyors to providing alarm signals during cleaning processes, ATEX compliant lamps ensure operators are alerted to potential risks. The IP65 protection of devices like the LR4-EX and LR6-EX makes them especially suitable for washdown environments.

Utilities & Energy

In power generation, renewable energy, and wastewater treatment facilities, operators depend on durable, intrinsically safe indicators to monitor pumps, motors, and process equipment. LED signal towers provide clear status visibility across noisy plant environments, while low-maintenance panel lamps reduce downtime and service costs.
