We’ve recently rolled out a major update to our elevator control system (ECS), which allows the ButterflyMX system to assign zones to elevators. Zoned elevator controls allow for selective control of different elevators within a building.
Please note that you can still wire in parallel to control multiple elevators in the same manner. Combining parallel wiring with zoned control means that Butterfly can accommodate a wide range of lockout schemes and resident-visitor interactions.
Below, we outline a potential scenario that would benefit from zoned elevator controls. Then, we describe how ButterflyMX solves the elevator access problem in that scenario.
Your building has two entrances with ButterflyMX video intercoms. There are also two separate residential towers, North and South. Each tower has a bank of 3 elevators with 10 floors.
You want visitors to access only the correct tower, and they must enter from the corresponding entrance. In other words, visitors to North Tower must enter at North Entrance and South visitors at South Entrance. However, they should be able to use any of the three elevators in the correct tower.
We assign zones to the towers. Zone 1 is North Tower and Zone 2 is South Tower.
Zone 1 residents only appear on the directory for the intercom at the North entrance. And Zone 2 residents only appear on the directory for the intercom at the South entrance.
Each tower requires two small ECS modules. The module in each tower is wired in parallel so that all three elevator cabs are unlocked on one request. Each tower has a floor-by-floor lockout.
