Napco Product Lines

Napco Security Technologies designs and manufactures alarm systems, fire alarm devices, communication modules, and locking hardware across several established product families. Their fire alarm division produces conventional and addressable detection devices engineered for reliability in demanding commercial environments.

The FW-2S two-wire smoke detector with integrated sounder combines photoelectric smoke detection and an audible alarm in a single device, eliminating the need for separate notification appliance circuits in smaller zones. This two-wire design reduces installation labor and material costs because the detector draws its power and communicates its status over the same pair of wires connected to the fire alarm control panel. When smoke is detected, the built-in sounder provides immediate local notification while the panel processes the alarm signal for the rest of the system.

Two-wire smoke detectors are particularly valuable in retrofit projects where pulling additional wire for separate notification circuits would require opening finished walls and ceilings. The FW-2S mounts to a standard base, and its photoelectric sensing chamber resists the false alarms that can plague ionization detectors in dusty or humid environments.

Napco's broader product portfolio includes the Gemini and StarLink families for intrusion detection and alarm communication. Gemini hybrid panels support hardwired and wireless zones on a single board, giving installers flexibility to mix sensor types based on the physical constraints of each site. StarLink cellular communicators provide primary or backup alarm communication paths that operate independently of the building's internet and telephone infrastructure.

Why Choose Napco

Napco manufactures its products in Amityville, New York, maintaining direct quality control over the engineering and production processes. Their U.S.-based manufacturing also means shorter lead times and responsive technical support for contractors who need answers during an installation.

The company designs its fire alarm and security products with the installer in mind. Consistent terminal layouts, clear wiring diagrams, and backward-compatible hardware mean that technicians who have worked with one generation of Napco equipment can transition to newer models without retraining. This practical design philosophy reduces installation errors and callback rates.

Napco products carry UL listings for fire alarm and burglary applications, meeting the code compliance requirements that AHJs verify during final inspection. Their fire alarm devices comply with NFPA 72 standards, and their intrusion panels meet UL 681 and UL 1023 requirements for central station and local alarm installations.
