Door entry systems


Recommended Posts

Has anyone hooked one up to their PBXnSIP install? I've got a customer asking if it's possible and I've found some devices which say they're SIP compliant door entry phone/door release devices, but they're rather pricey if they don't work. Has anyone got experience in this? Or maybe using other traditional PBX based entry phones and ATA's?

Yes, they are simply pricey. These devices traditionally are simply a FXO device attached to an FXS port on a traditional PBX as an extension. The push button on the door entry is pre-programmed to dial an extension or page group, the internal person that answers the phone, then enters the access code and internally the door entry closes a contact set and Voila'. Access control installers commonly install a remote button across those those contacts too. Some have to integrate MAG-LOCKS on that same door.


FYI, these are just as pricey in the TDM world, so don't feel bad about this..
