Kidde Homeguard Extension Tube Applicator for Safe Smoke Testing

The Kidde Homeguard Extension Tube Applicator (Model #1490) performs precision functional testing on conventional initiating devices within fire alarm and life safety systems. During periodic inspections, this accessory delivers smoke detector test spray directly into smoke sensors. The targeted aerosol application ensures smoke reaches the sensing chamber accurately, which verifies the operational readiness of residential and commercial smoke detection systems.

This component satisfies routine testing and maintenance mandates governed by NFPA 72 (National Fire Alarm and Signaling Code). NFPA 72 requires periodic testing of fire alarm initiating devices to verify that smoke detectors respond properly to simulated products of combustion. Using a specialized test applicator ensures code-compliant, repeatable functional checks without damaging sensitive sensing components.

Key Features & Construction

• Durable Construction: Built from rugged polymer materials designed to withstand repeated daily handling by fire protection contractors across residential and commercial job sites.
• Targeted Reach: The flexible extension tube design allows you to direct smoke test spray accurately into high ceilings and hard-to-reach detector configurations.
• Optimized Delivery: Engineered specifically for compatibility with standard smoke detector test sprays, enhancing spray precision and minimizing aerosol waste.
• Job Site Efficiency: The simple, lightweight setup enables fast, reliable functional testing during routine life safety system inspections.

Technical Specifications & Compliance

Always verify local Authority Having Jurisdiction (AHJ) testing mandates and review the manufacturer technical documentation prior to beginning smoke detector inspection procedures.
