Technical Specifications
Wireless Keypad Model CRS5000


  • Compact case. Rugged ABS plastic construction.Styled to fit comfortably in hand.Wearable with optional lanyard.
  • Dimensions: 3 in. L x 1.5 in. W x 0.4 in. H.
  • Weight: Less than 1 ounce (0.8 ounce /23 grams) with battery installed.
  • Color: Black. (Other colors available. Cost premium, minimum order quantity, and special terms apply.)

User Identification

  • Each keypad has an RF device identity ("address") between 1-250 and a channel identity between either 1-15 (standard version; stocked item) or 1-72 (custom arena version; special order; special terms and pricing apply).Addresses may be changed by using an optional WRS960X-T portable programmer.
  • Each keypad also has a unique device serial number.Serial numbers are permanent and set during manufacturing.
  • Both address and serial number identification are transmitted with each keypad's response.

User Input

  • 5 elastomeric buttons for entering multiple choice responses. Buttons are labeled 1-5, A-E.
  • Entries can be "speed scored" to 0.05 second (50 milli-second) resolution to identify group response sequence ('fastest finger') during competitive events.


  • Green and red LED lights to confirm user keypresses and indicate when the Base Station accepts the keypad's inputs.

RF Technology

  • Two-way RF keypad uses eligible license-free/license-exempt frequencies to communicate key presses to the Base Station and receive from the Base Station control information and acknowledgments of successful entries.
  • Employs Fleetwood-engineered 2.4 GHz frequency hopping spread spectrum (FHSS) transceivers.FHSS offers excellent range, immunity to interference, and signal security.
  • Patented and proprietary radio protocol.Creates a secure communications network between keypads and their associated Base Station.User entries are acknowledged when received by the Base Station. This message acknowledgment method is just one of the many patented features of Reply® systems.Permits Reply® systems to operate in the presence of other RF devices (WLANs, PDAs, phones, etc.).Integrated error checking discriminates system signals from all other RF traffic to ensure data accuracy and enhance security.
  • Depending on version, 15-72 channel identities are available to provide installation flexibility and support up to 3,750-18,000 keypads per room.
  • Internal antenna is protected by the keypad enclosure.


  • Reply® Mini is designed to operate in an indoor area 300 x 300 feet. [Note: Other Reply® products offer greater range. See appropriate specification sheets or contact us.]
  • A room's geometry, radio propagation characteristics, and proximity to RF interferers will influence actual range experienced. Elevating the base station often results in a performance advantage.


  • 250 keypads per Base Station channel identity. [Note: Other Reply® products offer higher capacity. See appropriate specification sheets or contact us.]Stock configuration: Default. 15 identities available for 3,750 keypads per room/site.Arena configuration: Non-stock. Special terms and pricing apply. Up to 72 identities for 18,000 users per venue.


  • Determined by Base Station. See Base Station Model CRS940 specification.
  • Time stamping is available to identify each keypad's input sequence in group's response.

Power and Power Management

  • Powered by one replaceable lithium coin cell battery.
  • Keypad powers down after each response transmission to conserve battery life.
  • Battery life is ~20,000 responses or battery shelf life, whichever comes first.
  • Low battery indicated on display. Also, keypad can transmit a low battery warning to Base Station.

Communications Security

  • A proprietary response verification protocol integral to the radio design provides a high degree of signal security.
  • Frequency hopping and proprietary data communications are additional deterrents to clandestine interception.


  • Firmware resides in high performance microprocessor chips that can be reprogrammed to facilitate upgrade during the life of the product.
  • Adding keypads to an existing system requires them to be set to unused addresses. No change is required on the Base Station when adding keypads of the same channel identity.

Compliance and Patents

  • FCC, IC, CE certified. Call for details regarding these and other regulatory certifications.
  • U.S. Patent Nos. Re. 35,449; 5,724,357; 6,021,119; 6,665,000. European Patent No. EP 0 697 773. Other U.S. and foreign patents and patents pending.


  • 2 YEAR (limited warranty, factory parts and labor). Call for details.
