EDC Turnstiles Alvarado's EDC turnstiles are the perfect choice for high volume patron counting applications. The EDC (shown at right) and EDC Bullnose (shown below) feature precision cast internal components, a smooth, hydraulically dampened arm rotation, and a very comfortable patron passage width. For installations were power is not available, the EDC uses a mechanical microswitch to output counts to a local battery powered digital counter, and/or Alvarado's GateWatch™ computerized patron counting software. For applications where power is available, electrically controlled EDCX models utilize a state-of-the-art controller with opto-interrupter rotation detection. This feature, offered exclusively by Alvarado, eliminates the need for mechanical microswitches and the accompanying adjustments that are often required. All EDC models are available as fixed or portable units, and may be ordered in extended configurations, with longer arms and cabinets. Cabinets are available in satin stainless steel, as well as a variety of durable powder coat finishes.
