4-Door Fire Door Hold Open Kit with PSU & 4 Magnets | 4-DR24-KIT

The 4-DR24-KIT is a complete 24V DC fire-door hold-open package for four doors. It combines one dedicated retainer power supply with four electromagnetic door holders for a convenient multi-door hard-wired system.

What is included?

• 1 x A-2401/4TRS 24V DC fire-door retainer power supply
• 4 x Geofire DR/ABS/24/200 24V DC electromagnetic fire-door holders

How it works

The holders retain compatible self-closing fire doors while energised. When the correctly designed fire-alarm interface removes power, all four magnets release and the existing door closers can return the doors to the closed position.

Use only as part of a correctly designed fire-door and fire-alarm strategy, with compatible doors, closers and interfaces.
