The Kidde EC5000R covers large open spaces - warehouses, atriums, industrial plants, gymnasiums - with a single reflective beam smoke detector that auto-aligns itself and stays locked on. The integrated laser guides reflector placement during install, and the AutoOptimise motorized head keeps the beam on target as the building settles and shifts over time. Ground-level controller with LCD means no lifts or ladders for routine maintenance and testing.

Built for the commercial fire installer

The EC5000R is a 4-wire conventional device connecting to any compatible FACP. One controller supports up to two detector heads, each covering up to 330 ft to the reflector with a single prism (27-160 ft) or the optional Long Range Prism Kit (160-330 ft). Total lateral coverage reaches 60 ft per beam, giving each detector head up to 19,800 sq ft of protection under flat ceilings. UL 268, ULC S529, FM Approved, CSFM, and MEA listed.

Key features

  • Auto-alignment with integrated laser: speeds reflector placement and eliminates guesswork during install
  • AutoOptimise motorized head: continuously self-corrects beam position to compensate for building shift and structural movement
  • Contamination compensation: automatic gain control adjusts for gradual lens dirt buildup, reducing nuisance trouble signals
  • Ground-level LCD controller: set up, test, and maintain the system from the floor without a lift
  • Built-in electronic UL/ULC fire test: run accepted obscuration testing without smoke or filters
  • Programmable alarm thresholds: 10% to 60% obscuration in 1% increments for application-specific tuning

System requirements

Requires a 4-wire connection to a compatible fire alarm control panel (14-36 VDC). Cabling between detector heads and the controller uses 24 to 14 AWG shielded pair. Reflector must be mounted on a secure, non-reflective surface with clear line of sight to the detector head. For installations beyond 160 ft, order the Long Range Prism Kit (5000-004) separately.

FAQs

How many detector heads can one controller support?
Up to two detector heads per ground-level controller. Each head operates independently with separate alarm and trouble contacts.
What's the difference between single-prism and long-range setup?
The EC5000R includes one prism for detector-to-reflector distances of 27 to 160 ft. For distances of 160 to 330 ft, order the Long Range Prism Kit (5000-004), which adds three additional prisms arranged in a group of four.
Does the detector compensate for building movement?
Yes. The AutoOptimise motorized head continuously self-corrects beam position to compensate for building shift and structural settling. Automatic gain control also adjusts for gradual lens contamination.
How do I run a fire test without smoke?
The EC5000R has a built-in electronic UL/ULC approved obscuration test. Initiate it from the ground-level LCD controller - no smoke, filters, or lifts required.
What panel compatibility does this require?
The EC5000R is a 4-wire conventional device (14-36 VDC) that connects to any compatible fire alarm control panel. It provides separate alarm and trouble relay contacts.
What applications is the EC5000R designed for?
Large open spaces with flat or angled ceilings: warehouses, hotel atria, industrial plants, school gymnasiums, convention centers, and places of worship. Coverage up to 19,800 sq ft per detector head.
