This is the original London Electricals training page for residents at Welbeck House. The video explains the BPT Perla indoor station and the porter functions configured for that building. Residents can use it as a refresher for their own installation; other buildings have their own programmed functions.
The controls available to a resident depend on the installed BPT system and the building configuration.
Use the communication control demonstrated for the Welbeck House unit.
Speak to the caller and confirm who they are before releasing a door.
Use the door-release control only for a visitor you intend to admit.
End the call in the normal way shown in the training.
If the picture, sound or door release does not behave as shown, do not repeatedly press every button. Make a note of the time, entrance and symptom so the building team can investigate the correct part of the system.
Calling the porter
The porter call is a programmed building function. Follow the exact control shown in the Welbeck House video and allow the call time to connect. The same button position on a Perla unit elsewhere may be assigned differently, so residents in another building should use their own handover guide.
Ringtone privacy and missed calls
Perla models can support ringtone adjustment or privacy indications, but the available behaviour varies with the model and system. If the unit appears silent, first check the resident-accessible ringtone setting shown in the guide. Do not factory-reset the indoor station or change communal settings.
The manufacturer’s CAME BPT intercom product guide gives further background on the Perla family. The Welbeck House video shows the functions configured for this building.
What to record when asking for support
The building and flat, shared only with the responsible support team.
The model or a clear photograph of the indoor station.
Whether the problem affects calls, audio, video, door release or the porter function.
Which entrance was used and the approximate time of the test.
Whether other residents have the same issue.
A fault affecting several flats may sit in the communal system rather than an individual handset. Keeping the report specific helps avoid unnecessary changes inside the flat.
Intercom design or support
For a new scheme, refurbishment or an existing fault, see our BPT CAME XIP intercom service. Include the site location, system information and the exact symptom when you contact us. Never send entry codes or account passwords through a general enquiry form.
