What Are Remote Heads?

Remote heads are separate lamp heads connected back to an emergency lighting power source, usually a battery unit, combo unit, or central emergency lighting system. Instead of relying only on the lamps mounted on the emergency unit itself, remote heads let you place emergency illumination where it is actually needed along the egress path. Modern versions are commonly LED, but older installations may still use incandescent or other legacy lamp styles. The practical point is simple: the head itself is only part of the system. It must be electrically and mechanically suitable for the power source that feeds it.

Where Are Remote Heads Used?

Remote heads are widely used in commercial buildings, schools, apartment common areas, warehouses, offices, retail spaces, and light industrial facilities. They are especially useful where the emergency unit cannot be mounted in the ideal lighting position, or where one battery pack needs to serve multiple points along a corridor or stair landing. They are also common in retrofit projects where an existing emergency unit still has spare remote capacity and the goal is to improve coverage without adding a full second unit. In utility rooms, service corridors, and back-of-house areas, remote heads can be a cost-effective way to extend emergency lighting while keeping maintenance concentrated at the main unit.

How To Choose Remote Heads

Start with system compatibility. Confirm the output voltage of the emergency unit, the lamp technology it is designed to support, and the maximum remote load it can carry. Then look at the application: indoor heads for finished interior spaces, damp or wet location heads for parking structures, exterior doors, canopies, or washdown-prone areas. Next, consider beam pattern and adjustability. Narrower beams can help in long corridors or stair runs, while broader distribution may suit open rooms. For replacements, match the existing aesthetic and mounting style where possible, but do not assume all remote heads are interchangeable across brands or generations. If the existing unit is older, verify whether a modern LED head will operate correctly on that output.

Trade Rules Of Thumb

A practical rule of thumb is to treat remote heads as a system-matching purchase, not a generic lighting accessory. If the emergency unit nameplate or documentation does not clearly state remote capacity, stop and verify before adding heads. For retrofit work, replacing old incandescent heads with LED heads can reduce load, but only if the emergency unit output is compatible with the new head design. In long corridors, more lower-output heads placed strategically often provide better coverage than one poorly aimed head at the far end. In stairwells, aim for useful landing and tread visibility rather than simply adding the maximum number of heads. These are typical field practices only and do not replace photometric layout, product instructions, or code review.

Sizing Guidelines

The first sizing step is electrical, not visual. Add up the connected remote head load and make sure it stays within the emergency unit's rated remote output. Confirm voltage and, where relevant, wattage or current draw per head. The second step is coverage. Larger open areas may need wider beam distribution or more heads, while corridors and stairwells often benefit from directional aiming. As a rule of thumb, remote head spacing should never be guessed from normal lighting expectations alone because emergency illumination targets are different from everyday lighting levels. For code-sensitive layouts, use manufacturer data and project requirements to confirm spacing, aiming, and run time. Where conductor length is significant, also consider voltage drop and installation method.

Common Installation Practices

Common practice is to mount remote heads where they can light the path of egress effectively without being blocked by doors, shelving, ductwork, or architectural features. Heads are usually aimed during commissioning so the beam reaches floor level, landings, or direction changes rather than shining into occupants' eyes. On retrofit jobs, electricians often reuse existing wiring routes if conductor condition and system compatibility are acceptable. It is also common to keep remote heads on the same manufacturer family when replacing visible fixtures in finished spaces, especially where appearance matters. Follow the emergency unit wiring diagram, polarity requirements if applicable, and environmental rating instructions. Installation and circuit design must comply with applicable Canadian codes and local inspection requirements.

Common Mistakes

The most common mistake is assuming any remote head will work with any emergency unit. Voltage mismatch, incompatible lamp technology, and excess connected load are frequent causes of failure. Another common issue is choosing heads based only on appearance without checking beam spread or environment rating. In retrofit work, buyers also sometimes overlook whether the existing unit battery and charger are still healthy enough to support added remote load. Poor aiming is another field problem: even a good head can perform badly if it is pointed too high, blocked by building features, or installed too far from the area that needs illumination. Finally, do not treat emergency lighting as ordinary decorative or task lighting. Coverage and compliance need to be reviewed as an emergency system, not just as a fixture swap.

Brand Comparisons

Aimlite, Beghelli, Ready-lite, Ortech, and Etlin Daniels are all recognized names in this category, and the right choice often depends on the installed base and the job type. Aimlite and Ready-lite are commonly specified where commercial emergency lighting compatibility and replacement continuity matter. Beghelli is often cross-shopped for commercial and institutional applications where a broad emergency lighting offering is useful. Ortech can be a practical option for standard applications where buyers want straightforward replacement choices. Etlin Daniels is often considered where value and general commercial coverage are priorities. In many retrofit situations, matching the existing brand may be the safest path for appearance, mounting, and system compatibility. For new work, compare the remote head against the power source, environment rating, and beam pattern first, then brand preference second.

Related Products

Remote heads are typically purchased alongside emergency battery units, combo exit signs with battery backup, replacement batteries, test switches, faceplates, and mounting accessories. Depending on the project, buyers may also need emergency lighting units with remote capacity, wet location emergency fixtures, exit signs, and replacement lamps or LED-compatible retrofit parts. For service work, it is often helpful to confirm the condition of the battery unit itself before ordering multiple remote heads, especially on older systems where charger, battery, and lamp compatibility may all affect the final result.

Frequently Asked Questions

Can I use any remote head with any emergency lighting unit?

No. You need to match the remote head to the emergency unit's output voltage, supported lamp type, and available remote load capacity. Brand family can also matter on retrofit jobs.

Are LED remote heads a direct replacement for older incandescent heads?

Sometimes, but not always. LED heads often reduce load, which can help, but the emergency unit still has to be compatible with the LED head design and operating voltage.

When should I choose wet location remote heads?

Use wet location heads where the fixture may be exposed to rain, hose-down conditions, or direct weather. Damp or indoor heads are not a substitute where the environment requires a higher rating.

How do I know how many remote heads an emergency unit can support?

Check the emergency unit nameplate, cut sheet, or manufacturer documentation for remote capacity. Do not estimate by appearance alone, because battery size and output rating vary widely.

Is it better to match the existing installed brand on a replacement job?

In many cases, yes. Matching the installed brand can simplify fit, appearance, and compatibility, especially in commercial buildings with standardized emergency lighting equipment.

Do remote heads come pre-aimed?

No. They are typically adjustable and should be aimed during installation and testing so the emergency light reaches the intended path of egress or open area.

Can remote heads be used outdoors?

Yes, but only if the specific head is rated for the environment and installed according to the manufacturer instructions. Outdoor and exposed locations usually require wet location equipment.
