    I work for a major grocery chain and they want to convert some entrances that have aytomatic sliders to emergency exit only status. I would like to have a 15 second delayed egress at the door with an alarm. I got a quote from the door mfg to install a solenoid to prevent the doors from sliding and they will just breakaway in an emergency. Does anyone have any advice on this? Thanks in advance.
