I am an electrician trying to pipe in alarm system. The diagram i have shows using a light engineered display panel a pull station,and two notifier fcm1 modules right next to the display, at all exits of the building. My question is one of locating the notifier modules. If i were to enterpret the drawings it looks like i mount these modules right next to the display above the door. I can find no where that gives me guidance on the placement of the boxes these will mount to. So i came here.
