Due to the layout of the property I would not have access to the keyswitch in order to bring the fire curtain back up manually; how can the fire curtain be brought back up?

In case of a false alarm, once the signal is lost to our control panel the fire curtains will automatically retract. Please note that if the fire curtain is set to automatically retract the key switch provided will be made redundant, so cannot be used in order to test the functioning of the fire curtain. The fire alarm will have to be set off in order to test the fire curtain.
