Dorgard X allows fire doors to be held open safely and legally. When the fire alarm sounds Dorgard X receives a radio signal from a System X Transmitter to release its hold on the fire doors, preventing the spread of fire and smoke.
It is often inconvenient to keep your fire doors shut; however it is against regulations to wedge them open. Dorgard X enables fire doors to be kept open safely and legally.
The versatile System X Transmitter can either be a fully wireless acoustic system, being installed next to the fire alarm bell, or hardwired into the fire alarm system.

Acoustically Linked Mode
The System X Transmitter leaves the factory configured in the acoustically linked mode. This means that when the System X Transmitter is installed it continually monitors the sound pressure levels of the surrounding area. When a fire alarm is activated, the sound pressure level it generates and its frequency content is analysed to determine that an alarm has been activated. On identifying an alarm condition, the unit automatically signals to all linked devices to close the fire doors. One unit can transmit simultaneously to multiple Dorgard X units within a 100 metre range, subject to a site specific survey.
During installation the System X Transmitter can be hardwired directly into an automatic fire detection and alarm system, or an input/output unit on an addressable loop. The System X Transmitter then continuously monitors the status of the FIRE relay within the control and indicating equipment. On identifying an alarm condition the unit automatically signals to all linked devices to close the fire doors. One unit can transmit simultaneously to multiple Dorgard X units within a 100 metre range, subject to a site specific survey.
