Any keyset extension that receives Door Box chimes can control a system relay, which in turn typically
enables an electric strike on an entrance door next to a Door Box. After answering the Door Box chimes, the
extension user can press FLASH or a soft key to enable the associated relay. The visitor at the door can then
enter without having an employee open the entrance for them. DS1000 has 2 relays, located in the DOOR1
and DOOR2 analog Door Box jacks. You can assign these relays for Door Box strike control or Page Relay
Control, but not both.
DS1000 Analog Door Box
The system uses Ring Groups to control Door Box chimes. When a visitor at the door presses the Door Box
call button, the Door Box will alert (chime) all the extensions in the Ring Group to which the Door Box
belongs. For example, if the Door Box and extensions 301 and 302 are in Ring Group 1, pressing the call
button alerts 301 and 302.
By default, DOOR1 (extension 324) and DOOR2 (extension 325) are reserved for analog Door Boxes.
