FIREscape Nepto N89R-O-3 | High-Powered Open Area Recessed Emergency Luminaire | BS 5266 Compliant
£88.04 (inc VAT: £105.65)
Summary
The Hochiki N89R-O-3 is a high-powered, addressable open area recessed luminaire, designed as part of the FIREscape Nepto emergency lighting system. Combining high-power Li-ion battery technology with the latest LED light source, this unit delivers a circular illumination pattern that makes it equally well suited to standard open areas, high-ceiling environments, and higher-risk spaces where greater light output is required.
As an addressable luminaire, the N89R-O-3 connects to the FIREscape Nepto control panel via a single pair of cables that carry both energy and data — simplifying installation and reducing cabling requirements. The unit comes pre-assembled with a sprung fixing mechanism for straightforward recessed installation into ceilings up to 25mm thick, and with an IP55 rating it can be deployed in a wide range of building environments.
Fully compliant with BS 5266 and its mandatory 3-hour emergency duration requirement, the N89R-O-3 is a reliable, low-maintenance choice for installers specifying addressable emergency lighting for commercial, industrial, or public buildings. Note: a Li-ion/2900 battery is required and sold separately.

FAQ
What is the Hochiki N89R-O-3 and which system does it work with?
The N89R-O-3 is a high-powered, addressable open area recessed emergency lighting luminaire. It is part of the Hochiki FIREscape Nepto addressable emergency lighting system, which consists of an intelligent control panel connected to a range of addressable LED luminaires and exit signs via extra-low voltage cabling.
What kind of light pattern does the N89R-O-3 produce?
The N89R-O-3 uses a circular lens to produce an open area light pattern, designed to illuminate a wide floor area below the fitting. This makes it suitable for general open-plan spaces as well as higher-ceiling or higher-risk environments where greater light output is needed.
How is the N89R-O-3 wired into a system?
The unit requires just a single pair of cables to connect to the FIREscape Nepto panel. That single cable run carries both power and data, which significantly reduces cabling compared to conventional emergency lighting systems and keeps installation straightforward.
Does the N89R-O-3 come with a battery?
No — a Li-ion/2900 battery is required but sold separately. Once fitted, the battery provides the backup power needed to run the luminaire for the required 3-hour emergency duration. A full charge takes 12 to 24 hours.
How long will the N89R-O-3 operate during a power failure?
The N89R-O-3 provides a 3-hour standby duration when running on battery power, meeting the requirements set out in BS 5266 for emergency lighting duration.
Is the N89R-O-3 suitable for high-ceiling installations?
Yes — the high-powered output of this model makes it specifically suitable for mounting on high ceilings or within high-risk areas where standard-output luminaires may not provide sufficient illuminance levels at floor level.
What is the IP rating of the N89R-O-3?
The N89R-O-3 carries an IP55 rating, meaning it is protected against dust ingress and low-pressure water jets from any direction. This makes it suitable for use in a broad range of commercial and industrial environments.
What ceiling thickness is the N89R-O-3 compatible with?
The pre-assembled sprung fixing on the N89R-O-3 accommodates ceiling thicknesses of up to 25mm, covering the majority of standard suspended and plasterboard ceiling constructions.
