Fire-Lite FM998 Door Holder - Reliable Electromagnetic Hold Open

In this review the Fire-Lite FM998 is evaluated as a practical electromagnetic door holder for fire and smoke barrier doors. The FM998 is aimed at building managers, electricians, and contractors who need a dependable hold-open solution that releases on an alarm signal. The single biggest reason to buy is its simple, rugged design that supports multiple voltages and provides fail-safe operation, making it easy to integrate with smoke detectors and standard closing devices. For installations requiring a compact, protected electromagnet with consistent holding force, the FM998 delivers straightforward performance.

Key Features

• Multi-voltage support: Works with 12 VDC, 24 VAC/VDC, or 120 VAC so it fits diverse control systems without special models.
• Fail-safe operation: Releases the door automatically when power is removed, ensuring compliance with safety systems and emergency requirements.
• Solid holding power: Provides roughly 25 to 40 pounds of holding force suitable for many interior fire and smoke barrier doors.
• Transient protection: AC models include protection against surges up to 600 volts to improve reliability in noisy electrical environments.
• Adjustable armature plate: The armature contact plate has an adjustable pivot mounting for accurate door alignment and installation ease.
• Flexible mounting options: Enclosure mounts on wall or floor behind the door and a spacing kit handles odd angles during installation.

Who It's For

The FM998 is best for commercial and institutional settings where doors must be held open under normal conditions and released by a fire alarm or detector, such as schools, hospitals, and office buildings. Installers who need a unit that accepts common control voltages will appreciate not having to stock multiple voltage-specific models.

Those who should look elsewhere include projects requiring extremely high holding force beyond the stated 25 to 40 pounds or systems that need an integrated closing device; the FM998 is a door holder and requires a separate door closer for full door control.

Pros & Cons

Pros

• Supports multiple voltages, reducing inventory complexity for installers.
• Fail-safe design ensures doors release on power loss or alarm activation for safety compliance.
• Protected against electrical transients on AC models, which enhances longevity in industrial environments.
• Adjustable armature plate and spacing kit simplify alignment and odd-angle installations.

Cons

• Holding power is moderate (25 to 40 lb) and may not suit very heavy doors without additional hardware.
• The product requires a separate closing device, so it is not a complete door control kit on its own.
