ANSWER: For security card readers, the elevator package of design provides conduits inside the monument.

As far as CCTV inside the monument, the existing cables for the CCTV cameras are being demolished and replaced with the same type of cable (match existing).

The digital displays referred to must be the digital displays within the cab. The cabling for that is part of the Elevator scope of work.

All security system information and specifications are located in the VSF 28 series specifications. Refer also to the system on-line (drawing SE5.4 in the VSF package)

14. Please verify if the remote diagnostic panel with camera system at the ground floor is the same as the computer system to tie in the camera system?

2) The CCTV system is part of the NPSs CCTV system. In the WAMO, the CCTV work consists of demolishing the existing cables associated with the 2 cameras that are connected to the elevator, and replacing the cables in kind.

3) Digital Video Display within the cab. This system is not connected to either the CCTV system or the Remote Diagnostic System – it is for displaying information to visitors and falls under the Elevator scope or work.
