The Aiphone GT-MK Concierge Station for the GT Series Multi-Tenant System is used to communicate with a GT entrance panel or individual tenant stations. It can be included in either an audio only or audio/video system. It features a 10-key keypad for calls to both tenant stations and entry panels and a handset for private communication. This station surface mounts to a single gang electrical box or may be desk-mounted using an optional GFW-S desk stand. It also has up/down buttons for name scrolling and a door-release button to selectively open the entrance where communication has been established.
The GT-MK has two calling modes—standard (via tenant station) and emergency (via GFK-PS). When a standard call is placed, a normal call tone is heard and the calling unit’s name and number are displayed on the LCD screen. When the emergency call is placed, an urgent call tone is heard and the calling unit’s name and number flash on the LCD screen intermittently as “Emergency.” A standard call is reset by hanging up the GT-MK handset and emergency call must be reset at the tenant location.
The GT-MK can be manually programmed or programmed via a PC using the supplied USB cable. A standard GT Series system will support 2 GT-MK while an expanded system will support four GT-MKs. The system has one talk path. When the system is occupied, a busy tone will be heard if another call is attempted.
