What Novar does

Novar GmbH, trading as ESSER by Honeywell, is a German-based fire detection and voice alarm systems manufacturer and a wholly-owned subsidiary of Honeywell International. The company designs, produces, and distributes addressable fire detection, voice alarm/public address (PAVA), aspirating smoke detection, and connected life safety services for infrastructure, industrial, hospitality, healthcare, public buildings, commercial, and cultural facilities. Its principal footprint spans Germany and Austria, with additional direct presence in the Iberian market via the Honeywell Life Safety Iberia headquarters. Named reference installations include Phantasialand (theme park), Kunsthalle Weishaupt and the International Maritime Museum Hamburg (cultural venues), Rohde & Schwarz (industrial/electronics), Correctional Facility Tilburg (government), Rhein Main Congress Center Wiesbaden (public/commercial), and HIMO Craftsmen Innovation Centre (commercial). Klaus Hirzel serves on the Board of Directors.

The core technology stack rests on the FlexES control platform and the proprietary esserbus ringbus protocol, which integrates addressable detectors, transponders, control panels, and notification appliances into a single supervised loop. The detector range is anchored by the IQ8Quad family, including ATEX-certified intrinsically safe variants for hazardous zones, complemented by VESDA-E aspirating smoke detectors, LRMX linear smoke detectors, UV flame detectors, and linear heat detectors. The voice alarm portfolio centers on VARIODYN ONE (current generation, launched 2020) and VARIODYN D1 (legacy), with INTEVIO extending coverage to small and mid-size buildings. Newer additions — Li-Ion Tamer for lithium-ion battery off-gas detection and the CLSS cloud platform — point to a pivot toward energy-storage safety and recurring connected-services revenue.

Go-to-market operates primarily through system integrators, electrical installers, and specification channels, leveraging Honeywell's broader distribution network. Revenue is generated via one-time hardware sales of panels, detectors, and notification appliances, supplemented by engineering services and increasingly by cloud-mediated services under CLSS. The 2026 planned relocation of Neuss-based logistical operations suggests an active investment cycle around distribution scale. Because Novar is a non-listed subsidiary, headcount, revenue, and order-book disclosures are not publicly available, which constrains the precision of any external financial triangulation.

Product overview

Novar GmbH (ESSER by Honeywell) offers a comprehensive portfolio of fire alarm and voice alarm systems, managed through a modular product architecture. The core offering includes the FlexES fire alarm control system as the central platform, supported by addressable detector lines (IQ8Quad, IQ8Wireless), smoke aspiration systems (VESDA-E, LRS Compact, ARS70-2), and linear/detector-based detection. Voice alarm capabilities are delivered through VARIODYN ONE and VARIODYN D1 PA/VA systems, with the new INTEVIO covering small-to-mid-size building needs. Specialty detection includes Li-Ion Tamer battery rack monitors, UV flame detectors, and line smoke detectors (LRMX). Cloud connectivity is provided via CLSS (Connected Life Safety Services). Integration across the portfolio is enabled through esserbus and ringbus transponders, with remote system operation via the Ethernet Touch Call Station (ETCS). Accessories include detector test gas and mounting adapters.
