Use of louvered smoke vents for daily ventilation
In louvered vents daily ventilation is effected by actuators which open the vent to let the
smoke out.
In order to enable using the mcr LAM louvered vents w/ pneumatic actuators for daily
ventilation the pneumatic system must be provided with ventilation boxes (with a double-pipe
priority valve, such as VVAZ for smoke vents opened by alarm boxes) and the vent must be
fitted with a TAVZ thermal release valve (except for the vents equipped with a pneumatic
actuator and a gas spring).
