The Door Chime does not operate far away.
The range of the MiP Door Chime system is 150m unobstructed, as tested in laboratory conditions.
Walls, additional wireless signals, microwaves etc all reduce this range and in most cases the range can be reduced to 15-20m.
If you find that the distance is insufficient or you require a longer distance then Lloytron has now added an additional signal booster module that can be programmed with all MiP products.
It will allow the range to be extended by a further 150m unobstructed, can be linked to additional boosters and can also act as an additional door chime unit.
The product code for this Signal booster is B7890WH and is available at all good retailers.
