Doorphones connected to PBX through existing telephone network allows pepole who intend to enter closed area to communicate with people in that area. In addition they allow activate electrolock or relay (EZ or STA) to control opening of door or gate using:
- telephone with which is call by selecting appropriate DTMF code on acoustics - * (asterisk) or digits 1 or 2
- RFID version - approach identifier
- POD (door open button)
DPH doorphones have following functional features:
- making a phone call using the capacitive button
- controlling two outputs with:
- electrolock (EZ)
- additional relay (STA)
- power suppply: 18-25V AC lub 14-35V DC
- operating temperature range: -20 to +50 o C
- security level - IP32
- detection of PBX notification signal (INACCESS) with following properties:
- frequency: 425Hz (+- 25Hz)
- Busy signal detection with the properties:
- frquency: 425Hz (+- 25Hz)
- signal/silence duration: 352ms - 608ms
- number of consecutive signal and silence sequences detected: 3
- detection of unreachable signal (CONGESTION) with properties:
- frequency: 425Hz (+- 25Hz)
- signal/silence duration: 192ms - 320ms
- number of consecutive signal and silence sequences detected: 3
- COD (door open sensor) and POD (door open button) inputs. Both inputs cooperate with electrolock
- EZ or STA trigger (open) as result of receiving "*" in DTMF, depending on setting of corresponding parameter
- EZ trigger as result of receiving "1" in DTMF
- STA trigger (second output) as result of receiving "2" in DTMF. Single pulse of constant duration is generated
- built-in RFID card reader (cards Unique 125kHz standard, compatible with EM4102 chip - doorphone version without RFID are also available)
- option of EZ or STA triggering as result of approaching registered RFID card (in selected versions)
- programming doorphone from phone using DTMF codes
