FIREscape Nepto N40-3 | Addressable Exit Sign Frame | 40m Viewing Distance, BS5266 Compliant
£69.94
Summary
The Hochiki N40-3 is an addressable exit sign frame designed for use within the FIREscape Nepto emergency lighting system, offering a viewing distance of up to 40m — making it the right choice for larger open spaces such as warehouses, sports halls, atria, and other high-volume environments where standard 20m signage would fall short. Like the N20-3, it accepts interchangeable directional lenses with ISO7010-compliant legends (sold separately), giving installers flexibility to specify the correct legend for each exit point.
The frame houses an integral long-life NiMH battery providing 3 hours of standby illumination in line with BS 5266 requirements, and connects to the FIREscape Nepto control panel via a single pair of cables carrying both power and data. It can be configured for either ceiling or wall mounting and twist-fits directly to Hochiki’s standard YBN-R/3(WHT) mounting base, ensuring a consistent installation process across a Nepto system.
The N40-3 is supplied in white and is available as a frame only — directional lenses with ISO7010 legends must be ordered separately, allowing the appropriate direction to be chosen for each location.

FAQs
What is the Hochiki N40-3 and what system does it work with?
The N40-3 is an addressable exit sign frame that forms part of the Hochiki FIREscape Nepto emergency lighting system. It accepts interchangeable directional lenses with ISO7010-compliant legends (sold separately) and connects to the FIREscape Nepto control panel via a single cable pair carrying both power and data.
What is the difference between the N40-3 and the N20-3?
The key difference is viewing distance — the N40-3 is designed to be read from up to 40m away, while the N20-3 covers up to 20m. The N40-3 is physically larger to achieve this, and draws more power (0.53W versus 0.25W). The N40-3 also provides a 3-hour standby duration, whereas the N20-3 delivers 6 hours. The N40-3 is white only, while the N20-3 is available in black as well.
Are the lenses included with the N40-3?
No — the N40-3 is a frame only. Directional lenses with ISO7010-compliant legends are sold separately, allowing the correct directional legend to be selected for each exit point. This also provides flexibility if exit routes are reconfigured at any point after installation.
How long will the N40-3 operate during a power failure?
The N40-3 provides 3 hours of standby illumination on battery power, meeting the duration requirements of BS 5266 for emergency lighting and exit signage.
Can the N40-3 be mounted on both ceilings and walls?
Yes — the N40-3 can be configured for either ceiling or wall mounting, with slightly different overall dimensions for each orientation. Both configurations twist-fit to Hochiki’s standard YBN-R/3(WHT) mounting base.
What IP rating does the N40-3 achieve?
The N40-3 achieves IP55 when installed with the separate N-IP-GASKET sealing accessory. IP55 provides protection against dust ingress and low-pressure water jets from any direction, making it suitable for environments where some exposure to moisture is possible.
Where is the N40-3 most commonly specified?
The N40-3 is typically specified in larger spaces where a 20m viewing distance would not provide adequate coverage — for example, warehouses, distribution centres, sports halls, large open-plan offices, atria, and airport or transport terminals. Wherever occupants need to locate exit signage quickly across a wide floor area, the 40m-rated frame is the appropriate choice.
What type of battery does the N40-3 use?
The N40-3 uses an integral NiMH (nickel-metal hydride) battery rated at 1.2V / 1900mAh. NiMH offers reliable performance across a wide temperature range. Note that battery life shortens at elevated temperatures — above +30°C, battery life reduces by approximately two-thirds for every 10°C increase.
