Phone Controls
All phones have 2-way speech and a lock button to release the door. For security, phones
must be called first and taken off the hook before the lock release button will function; a stuck
lock button will be ignored.
Ringer Mute
With some models of telephone (801PS, 801S & BS-LX) the resident can mute the ringing
sound of their phone when they do not wish to be disturbed.
Model 801PS/801S phones: Sliding the switch on the right hand side to the ON position
enables the ringer whilst the OFF position disables (mutes) the ringer.
Model BS-LX phone: Ringer mute is activated by pressing the mute button on the phone,
which illuminates red as a reminder. Pressing the mute button a second time will disengage
the mute function. During installation it is possible to set a time limit for the mute function in
various values from 2 minutes up to 10 hours or indefinitely. When this time period has
elapsed the mute function will automatically disengage (See ‘Phone settings’ in the reference
section). The mute feature stops the audible ring, but the red mute light will still flash to
indicate a call and all other functions work normally. Ringer mute will continue for the preset
time even if a call is answered.
Door Status Indication – BS-LX Only
The green lamp on the phone illuminates to warn the resident that a door has been left open
following a call. This feature requires a door monitor contact to be fitted.
