Many people have a need to extend chimes to an office in the garden, or to the back of a property, to avoid missing the visitors or deliveries, which can mean delays and inconvenience. While wiring a system is the most robust method, it can be expensive, and a wireless system would seem the most popular option.
Getting a wireless signal from the front, through the house, and out to the back office, puts a limit on the capabilities of standard domestic systems. The first thing to consider is the front door frame. If it is UPVC or a metal type, the wireless signal is significantly weakened before it even enters the property. UPVC door frames have metal supports behind the plastic front, to strengthen them for security purposes, and it is this metal backing that shields wireless signals. It is often better with UPVC door frames, to place the wireless bell push button on a wall to the side of the door frame, or onto the door itself. Alternatively, if it possible to get a small length of wire around the doorframe, then a wired to wirefree converter/extender can be connected to a standard wired bell push button, and send a strong signal from within the property. Wooden doorframes are normally good for wireless systems.
There should be at least 2 chime units running from a single bell push button (always available with a wireless system). The office chime should be the maximum 200meter type. With Byron models we recommend the TX-501 twin pack, which includes the 200m chime, and which can benefit from the Byron EX-1 Signal booster, should the signal to the office is beweakened by thick walls etc. For Friedland models, we have found the Libra+ D917 chime to have the longest distance of all domestic chimes, and we suggest combining this unit with a Libra+ model D913. Unfortunately, there are no options for boosting signals in the Friedland range.
If all domestic chime options fail to bridge the distance by wireless signals, then the only remaining option is a Daitem Wireless Doorphone System. Although these are normally used for door or gate entry, they have the advantage of the much longer wireless distance of 400m (typical 100m). They also have the advantage of using an intercom handset to talk to visitors, and there is also the option of buying additional handsets to leave around the house to use as a doorbell. The online brochure Doorphone.pdf describes how these systems can help solve the "Office Doorbell" problem.
