Arguably the single most important fire safety mechanism, electromagnetic door holders guard against the lethal spread of toxic smoke and fumes - by far the greatest cause of death in fires.
The Vimpex EN 1155 approved weatherproof door holder offers the installer an excellent solution for harsh environments and outdoor use. Mounted onto a fixed surface, these door holders ensure retention of the fire door by means of a smart metallic keeper plate. Interfaced with the fire alarm system, the door holders are deenergised as soon as the fire is detected thus releasing the door without the potentially harmful delay suffered by other types of devices.
The LF-SI-6105 Signal Input Module provides the means of connecting Direct Shorting Devices to the Fire Alarm Control Panel. The module converts a normally open contact input which could monitor and report the status of the contact to the Fire Panel.
