Concierge Station for the GT Series
DESCRIPTION: FEATURES:
GT-MK
The GT-MK is a concierge station for the GT Series
multi-tenant system. The unit surface mounts to a single
gang electrical box or may be desk mounted using an
optional desk stand (GFW-S). The GT-MK features a
10-key keypad for calls to both tenant stations and entry
panels and a handset for private communication. The unit
also has up/down buttons for name scrolling and a door
release button to selectively open the entrance where
communication is 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 steady on the LCD screen.
When the emergency call is placed, an urgent call tone
is heard and the calling unit’s name and number ash on
the LCD screen intermittently with “EMERCENCY”. 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 PC using the supplied USB cable. A standard GT
system will support 2 GT-MK while an expanded system
will support 4 GT-MK.
