BELL DOOR ENTRY KIT 904 4 WAY
The Bell System 904 door entry kits are one of the more popular door entry systems due in the most part to their tough construction which offers both resistance to corrosion and general durability at a sensible price.
The units are both practical and aesthetically pleasing in all environments and locations and can be either surface or flush mounted.
The 904 system contains four model 801 telephone handsets which are especially recommended for use by the elderly due to their extra width. They incorporate a ‘lock release’ push-button which is cleverly located under the handset which helps to eliminate accidental activation or inadvertent use.
The ring tone has an added safety feature in that the tone volume is reduced when the handset if off the hook.
