Bell View Video Entry System General Description The bellview Video Door Entry Telephone System is a high quality, versatile security product for controlling access to private houses, residential homes, blocks of flats and offices. The occupants are supplied with individual video entry telephones which enable them to view the person calling at the entrance; to converse with the caller; and if desired allow them access to the building via an electric lock release.

Bell View Video Entry System System Operation General The entrance panel, which includes the camera and speech unit, should be located on a wall adjacent to the building entrance. A visitor can contact any resident by pressing the appropriate button on the entrance panel which will call the resident's video telephone (sounds a buzzer), activating the display and enabling speech. The resident can view the caller on the video screen and by picking up the handset freely converse with the visitor.
Bell View Video Entry System Equipment Required Control Cabinet / Power Supply For systems exceeding 10 ways or requiring battery backup, an IP55-rated, lockable steel cabinet is supplied, containing the power supply and control circuitry. This is available for smaller systems on request.
Bell View Video Entry System Telephones One model BV video door entry telephone is required per flat. The model 500PX series telephones (depending on the features required) may be used in place of one or more video telephones, if audio only is required. Entrance Panel One BVP series entrance panel is required per door. e.g. BVP5 BVP10-TRBV 5 way Panel 10 way panel with tradesman facility (11 buttons) Each entrance panel contains a model BV700 CCD Camera and a model 61 Speech Unit.
Bell View Video Entry System System Design Considerations Cable requirements Refer to one of the following sections according to your system requirements: System Section 1 way single door CW1 2-10 way single door CW2 11-60 way single door CW3 1-10 way 2 door CW4 11-60 way 2 door CW5 Multiple video telephones in one flat When several video telephones are installed in a single flat, it is usually necessary to disable the auto-display feature on all telephones (see page 13), to prevent the power s
Bell View Video Entry System Electric Door Release Fail-Secure releases are the most commonly used devices, they require power to release the lock and will secure the door upon power failure. Fail-Safe lock releases and magnetic locks require continuous power to hold the lock and will release the door upon power failure. All of these types can be accommodated providing they are rated at 12V DC with a maximum current consumption of 0.5A.
Bell View Video Entry System Installation 8
Bell View Video Entry System Important Safety Information Connections to the 240V AC mains supply must be carried out by a qualified electrician or similar competent person, and made in accordance with accepted safety practices. A two-pole switch (as provided by a Consumer Unit or Switch-Fuse) must be included to isolate both Live and Neutral during Installation or Maintenance.
Bell View Video Entry System General Select the appropriate wiring diagram from one of the following sections, and install in accordance with the instructions given: System Section 1 way single door CW1 2-10 way single door CW2 11-60 way single door CW3 1-10 way 2 door CW4 11-60 way 2 door CW5 Initially connect all the equipment to one telephone only. With the power applied, test the system is fully operational.
Bell View Video Entry System PSU138A, PSU138B Power Supplies Read the section called ‘Important Safety Information’ before installing the power supply. A good mains safety earth must be connected to the cabinet housing the power supply. The cabinet must be placed in a protected indoor environment and not exposed to dripping or splashing. The Cabinet must be secured to the wall with adequate fixings so that there is no possibility of it falling down.
Bell View Video Entry System Video Telephones (Refer to diagram 1) Also refer to the ‘Commissioning’ section for further information. IMPORTANT: The video telephone has a slide switch which terminates the coax cable with a 75S impedance. When more than one video telephone is installed, all video telephones must be set to HI (ie no termination) except the last telephone on each cable branch which should be set to 75R.
Bell View Video Entry System Commissioning Video Telephone settings Picture Adjustment To adjust the BRIGHTNESS and CONTRAST of the picture adjust the two thumbwheel controls at the left hand side of the telephone. Buzzer mute time This is he time for which the telephone buzzer will be switched off when the buzzer mute button is pressed. Set between 1 minute and 10 hours (see SW2 settings, overleaf).

LED Condition Steady GREEN System running from the mains. Flashing GREEN System running from the battery. Steady RED Output off; Battery charging. Flashing RED Output short circuit or battery low.
Bell View Video Entry System Fault Finding Speech Problems Low speech volume ! ! ! ! ! Constant tone/feedback when in use. ! ! ! ! ! ! Speech not audible when phone is live. ! ! ! No speech when the phone is buzzed ! ! ! ! Volume adjustment required on the Speech Unit, see page 16 under SPEECH ADJUSTMENTS. Speech Unit is not tight against the panel grill. Panel grill is blocked. More than one active telephone is off the hook. Speech Unit supply voltage low.
Bell View Video Entry System Video Problems Video picture impaired or unsynchronised. ! ! ! ! ! Some phone terminating slide switches have not been set correctly. Refer to page 12. Poor coaxial cable connection or screen not connected. Phone too close to a magnetic field, e.g. transformer. Coaxial cable running too close to mains cable. Coaxial cable is not of 75S type. Entrance cannot be seen at night. ! Picture does not appear when the phone is buzzed.
Bell View Video Entry System Miscellaneous Problems Telephone will not buzz. ! ! ! Telephone ‘DOOR’ button does not operate release. ! ! ! ! Trades, Exit button or Fire Switch inoperative. Lock release operates all the time. Telephone has not been called. Fault on 'Z' or 'O' line. Check shorting 'Z' or ’TRIG +’ to 0V at the Switching Unit (2 door) or Lock Timer (Single door M540/LT88) when live operates the release. Lock release supply low.
