FIREscape Nepto N20-3 | Addressable Exit Sign Frame | 20m Viewing Distance, BS5266 Compliant
£65.35
Summary
The Hochiki N20-3 is an addressable exit sign frame designed for use within the FIREscape Nepto emergency lighting system. The frame accepts a range of directional lenses carrying ISO7010-compliant legends (sold separately), providing clear, standardised exit signage visible from distances of up to 20m. With an integral long-life NiMH battery providing 6 hours of standby illumination — double the 3-hour minimum required by BS 5266 — the N20-3 offers a significant safety margin in the event of a prolonged power failure.
The frame can be configured for either ceiling or wall mounting, and twist-fits directly to Hochiki’s standard YBN-R/3(WHT) mounting base, keeping installation straightforward and consistent across a FIREscape Nepto installation. It is available in both white and black to suit a wide range of interior environments, from commercial offices and public buildings to hospitality and retail spaces.
Note that the N20-3 is a frame only — directional lenses with ISO7010 legends are sold separately, allowing the appropriate legend to be selected for each location within the installation.

FAQs
What is the Hochiki N20-3 and what system does it work with?
The N20-3 is an addressable exit sign frame that forms part of the Hochiki FIREscape Nepto emergency lighting system. It accepts a range of interchangeable directional lenses with ISO7010-compliant legends (sold separately) and connects to the FIREscape Nepto control panel via a single pair of cables carrying both power and data.
Are the lenses included with the N20-3?
No — the N20-3 is supplied as a frame only. Directional lenses with ISO7010 legends are sold separately, which allows the correct legend to be chosen for each specific location within the building. This also means lenses can be changed if exit routes are reconfigured at a later date.
How long will the N20-3 operate during a power failure?
The N20-3 provides 6 hours of standby illumination on battery power — double the 3-hour minimum duration prescribed by BS 5266. This provides a meaningful safety margin in situations where power is not quickly restored.
Can the N20-3 be mounted on both ceilings and walls?
Yes — the N20-3 can be configured for either ceiling or wall mounting, with the frame dimensions varying slightly depending on the orientation chosen. Both configurations twist-fit to Hochiki’s standard YBN-R/3(WHT) mounting base.
What colours is the N20-3 available in?
The N20-3 is available in white (ordering code: N20-3) and black (ordering code: N20-3(BLK)), making it suitable for a wide range of interior aesthetics where a standard white fitting may not be appropriate.
What is the IP rating of the N20-3?
The N20-3 achieves an IP55 rating when installed with the separate N-IP-GASKET sealing accessory. Without the gasket, a lower level of ingress protection should be assumed. IP55 provides protection against dust ingress and low-pressure water jets from any direction.
What type of battery does the N20-3 use?
The N20-3 uses an integral long-life NiMH (nickel-metal hydride) battery rated at 1.2V / 1900mAh. NiMH technology offers reliable performance across a wide temperature range, including cold environments. Note that battery life shortens at higher temperatures — above +30°C, battery life reduces by approximately two-thirds for every 10°C rise.
What mounting base does the N20-3 require?
The N20-3 twist-fits to Hochiki’s standard YBN-R/3(WHT) mounting base, which is the same base used across the FIREscape Nepto range. This consistency simplifies stock management and installation on multi-device projects.
