Senior Locator Systems
LT-49, RPN-99 and BUN-152


LT-49 (locator), RPN-99 (repeater) and BUN-152 (base unit) are a senior locator system designed for senior care centers. When elderly people press their RF pendants for help, LT-49 and RPN-99 receive the pendants’ signals and report the locations of those who need assistance to the base unit.

The functions of the system components are as follows:
LT-49 (locator): Receiving device signals and transmitting them to RPN-99 or BUN-152
RPN-99 (repeater): Relaying signals containing the same group number and system ID
BUN-152 (base unit): Receiving signals from LT-49 and RPN-99

This system enables monitoring personnel in large care homes to quickly know the identities and locations of the seniors summoning help. Each base unit can work with up to 4,096 locators and 4,096 repeaters.


  • Each system can integrate up to 4,096 LT-49s and 4,096 RPN-99s

  • Individual ID code for each locator and repeater

  • Three frequency-hopping groups available

  • Each frequency-hopping group contains 25 channels
