A Telephone entry system allows the person at the door to call the apartment or condo’s unit # by a Telephone System mounted on an adjacent wall. 
 
The person at the door will dial either the Telephone number or the Apartment number (Apartment 132). Our customer inside the apartment or condo will answer their phone and have the option of letting someone in the door by hitting a single digit on their phone.  When hitting this single digit, the system will then release the lock on the door and allow entry.
