SKU: WDK-ERA
Build a custom ERA commercial alert system around the ERA-DCRX receiver: pick a sensor, the receiver, and an alert accessory. It carries a wireless range of up to 4,000 ft, four programmable zones with a 12V DC output each, and support for up to 12 transmitters, which suits warehouses, factories, and large commercial spaces that need a warehouse entrance alert or loading-dock signal.
Use ERA when the distance between the door and the person who needs to hear about it is the actual problem.
Use ERA when the alert path has to cross a facility, yard, gate, driveway, warehouse floor, or separate work area.
Add receivers, push buttons, driveway sensors, motion sensors, strobes, sirens, and relay-capable accessories as the site grows.
Place the transmitter at the entrance and put receivers exactly where people act: shipping desks, counters, offices, shops, and service areas.
Use ERA for warehouse doorbells, loading dock alerts, entrance alerts, driveway alarms, doorbell extenders, curbside pickup, and remote visitor notification.
Most ERA projects are not won by the loudest receiver. They work because the trigger, receiver, and visual alert are placed around how the building actually operates.
Identify the entrance, gate, dock, or approach first. Then choose the transmitter or sensor that fits that trigger point.
Shipping desks, service counters, stockrooms, and offices are better receiver locations than a hallway where nobody is responsible for responding.
A strobe near the work area helps when machinery, distance, closed doors, or hearing protection can make a chime easy to miss.
Both cover a doorbell. The difference is how far the signal has to go, and how much you need to expand later.
