Bell Door Entry Telephone has been re-styled a number of times over the years and still maintains its classic design. This telephone operates from both 12V AC or 12V DC and is included in the standard model 900 and VRK audio door entry systems as well as the CS and CSP series of combined keypad and proximity door entry systems. The telephone is manufactured in white high-impact ABS plastic for high durability and complements most wall furnishings. It incorporates a ‘lock release’ push-button discreetly positioned on the base, and under the handset, to prevent inadvertent use. With its wide handset the model 801 is especially recommended for the elderly. The Electronic Ringing Tone has a useful safety feature whereby the tone is reduced when the handset is ‘off the hook’. The telephone has two levels for the ringing tone. A HI or LO position can be set within the telephone on installation or at future date.
