The Gamewell-FCI XP95 addressable detector range is one of the most widely used addressable detection platforms in North American commercial fire alarm systems. Originally developed by Apollo Fire Detectors and sold through Gamewell-FCI (now part of Carrier/UTC Fire & Security), XP95 devices are found in schools, healthcare facilities, hotels, and office buildings across the country. If you maintain or service these systems, understanding the XP95 product line — and where to source reliable replacement parts — is essential.
About the XP95 Platform
XP95 is an addressable analog detector protocol developed by Apollo Fire Detectors. It uses a two-wire SCI (Serial Communication Interface) loop to communicate analog values back to the fire alarm control panel. Each device on the loop has a unique address, allowing the panel to identify the exact location of an alarm or fault condition.
The XP95 protocol is panel-specific — XP95 devices are compatible with Gamewell-FCI panels designed to support the XP95 loop protocol, including the FCI 7100, E3 Series, and other Gamewell-FCI systems. When sourcing replacement detectors, it is critical to verify panel compatibility before ordering, as mixing detector protocols can result in communication failures.
XP95-P Photoelectric Smoke Detector
The XP95-P is the photoelectric variant of the XP95 detector range and one of the most frequently replaced components in Gamewell-FCI systems. It uses optical light-scattering technology to detect visible combustion particles, making it effective for detecting slow, smoldering fires — the most common fire type in occupied commercial buildings.
XP95-P specifications:
- Detection type: Photoelectric (optical)
- Protocol: Apollo XP95 analog addressable
- Operating voltage: 17–28VDC
- Quiescent current: Less than 300µA
- Alarm current: Less than 6mA
- Operating temperature: 32°F to 100°F (0°C to 38°C)
- UL Listing: UL 268
The detector head mounts to a separate base (sold individually), which remains wired to the SCI loop. This base/head separation allows detector replacement without rewiring.
XP95-B6EZ Base
The XP95-B6EZ is the standard mounting base for the XP95 detector range. It features a 6-inch footprint compatible with standard 4-inch electrical boxes and includes the loop wiring connections. The “EZ” designation refers to the tool-less detector locking mechanism, which simplifies installation and replacement.
Correct base selection matters: XP95 detectors require XP95-compatible bases. Using a base from a different addressable platform will not provide proper electrical connection or mechanical retention.
Sourcing XP95 Replacement Parts
Gamewell-FCI XP95 detectors and bases are available through fire alarm specialty distributors. Life Safety Consultants stocks XP95-compatible sensors and accessories for immediate shipment. The Gamewell-FCI XP95 sensor is available through our online store, making it easy to order the exact replacement your system requires.
For service contractors maintaining multiple Gamewell-FCI systems, keeping XP95 detector heads in truck stock ensures faster response when a detector fails on a service call. XP95 detectors are relatively robust, but age, contamination, and physical damage can cause individual units to fault or alarm spuriously — at which point replacement is the fastest path to system restoration.
Panel Compatibility and Address Setting
Before installing a replacement XP95 detector, confirm the following:
- Address setting: XP95 detectors use rotary address switches on the base to set the loop address. Match the replacement base to the address of the device being replaced, or reprogram via the panel if required.
- Panel software: Some Gamewell-FCI panels require detector model programming in the panel database. Verify the panel recognizes the replacement detector model.
- Loop loading: Confirm the SCI loop is not at maximum device capacity before adding or replacing devices.
