Elevator Lobby Door Systems

Many high-rise building tenants that occupy a complete floor may have a problem when it comes to securing their elevator lobby doors. The obvious reason is that these doors lead through office space to the emergency exit stairwell doors.

People must have free access to the stairwells at all times. This leaves some companies vulnerable to transient traffic, theft and loss of proprietary information. SDC manufactures a lobby door security system which meets both fire life safety and security needs.
