The Landmark 3416 module can be utilized to provide any one of three
features for the Landmark 416; music on hold, external paging or for door
monitor. Music-on-hold can be provided by connecting to various music
sources such as CDs or MP3 players to provide background music or
announcement to callers on hold. To provide paging, connect the device
to a paging amplifier and drive an external paging speaker. The module
can be paged from any phone in the system just by using its station
number. It can be set to accept or reject all pages. Multiple modules may
be connected to drive more than one speaker. When connected to a door
monitor, the phone will alert the user when the doorbell is pressed.
This also allows intercom conversation with the door monitor. The
Landmark 416 telephone has the capability to operate a magnetic door
strike enabling the door to be opened from the telephone dial pad.
Each of the features described above requires a module.
