Bell System 801 Door Entry Handset - White

Product Information

The grill covering the speech unit does not compromise audio quality, and the speech unit is securely fixed to the rear of the plate, making for a great door entry system.

One of the most popular kits on the market, the Bell 901 kit features a high quality intercom panel manufactured from 3 mm anodised aluminium with a brushed finish.

The model 801P handset is included in the standard model 900 and VRK audio door entry systems (more than 10 buttons on the door entry panel) as well as the CS and CSP series of combined keypad and proximity door entry systems. The handset uses traditional wiring which is 4 common wires, plus a call wire. Features: I should also point out the old handsets have an internal 'buzzer' within them, which buzzes when a visitor presses the Intercom.

The incoming wiring has red, blue (x2, for 2-way speech I presume), brown, grey (or at least it now looks grey after 20 or so years) and orange wires. The orange one goes to a single terminal (B) and then carries on to two other terminals (F and G). The others all go to single terminals. So...

Bell 801P | Door Entry Audio Handset With Privacy Of Speech

Unfortunately, but unsurprisingly, the new unit didn't come with any wiring schematics - or indications that it required 4+1 wires. In addition to the unit literally falling apart, the main issue was the fact that the caller couldn't hear the voice of the resident (using the handset in the apartment) while standing at the external Intercom (building entry door at street level). This issue increased the higher the apartments (the further away they were from the Intercom at street level).

The wiring is a 'loop' system feeding the left & right side of the building. (2 cables, 1 for either side) x aforementioned circuit cables (looping either side of apartment building), each side using 4 coloured wires (1 wire for each apartment) & common red. Posting in this forum as my 'issue' is similar to the OP - and desperately hoping for a swift reply. It had a speech unit (which allowed the 'resident' to hear the 'guest/visitor', and I assume the other way as well, perhaps?).

I've just bought a replacement handset (Bell 801) for my door entry system. The existing phone that I'm replacing has 5 wires going to different parts of the handset but their destinations are marked A B C etc. It appears to be an old "Entryphone" handset

My goal (if possible) is to simply replace the old 8-way Intercom system with a new unit, using the existing 8 internal handsets, using the existing wiring, and using the existing latch/door-release.The 'loop' system serves as a single cable supplying 4 apartments (4 apartments on the left side), and the same on the other (4 apartments on the right side). The kit comes complete with the 801 handset, which is one of the most popular handsets in the UK. Built from ABS plastic it is highly durable and with its smooth finish it is easy to keep clean. It is possible to have up to three handsets per button if required. However, upon installing it and trying to mimic the original wiring (from observing the original Intercom & speech module), it became clear that i needed more wires than i have (2 wires from each apartment) : ( The other coloured wires are present, but i now know that they feed the other apartments (see next point, Cabling).
