The DRW range of door retainers from Cranford Controls provides a simple and easy to fit solution for legally keeping fire doors open, combined with good looks, high performance and economy.
The DRW comes as a standard 24volt version or a mains 240volt operated version. Both are made with a flame retardant, low profile ABS plastic body coloured off-white. The 24volt DC models are also available in strong metal cased versions but are for wall mounting only.
Each DRW model is fitted with a spring loaded release pin mounted centrally within the electro-magnet. On power off, the release pin then ensures that the fire door is pushed away from the keeper plate KP-02. Both models are standiard intended for wall mouting, although an accessory FMB-04 is available to allow fitting to the floor.
All Cranford door retainers are designed to comply to the latest requirements of EN61000-3-2, EN50081-1, EN60950 and EN1155.
