Two-Way Radio Public Safety Enhancement




Project Information

























NFPA Compliance

The National Fire Protection Association (NFPA) code requires public safety signal enhancement equipment to be enclosed with a 24-hour power backup, monitoring capabilities, and hardened enclosures. The NFPA codes and standards have been adopted in many localities and strict compliance may have a notable impact on system costs. TESSCO Technologies has found that the following design solutions meet the requirements of many localities that have adopted the NFPA codes and standards:

Bi-Directional Amplifiers:
  • NEMA 4X enclosures - RED in color
  • Alarm Contacts
Power Backup:
  • 24-hour battery
  • Cream/White NEMA 3X with fan and vent covers or NEMA 4X enclosure
  • Alarm Contacts for A/C power loss and low battery

Tessco Technologies strongly advises all customers to consult with their local authority having jurisdiction for each specific project site to verify the specific local requirements, codes, and standards.
