Array ( [name] => holdopen [title] => Hold-Open Devices [content] =>
A hold-open device on a door closer allows the door to be set in the open position without the use of a door wedge.
Mechanical hold-open devices are unsuitable for use on fire doors as they do not release the door in the event of a fire. If you wish to use a hold-open device on a fire door it is recommended that you use an electronically controlled model which integrates with the fire alarm system and releases the door when the alarm is activated. Electro-hydraulic hold-open devices also release in the event of a power outage.
