Product information

Description

Ajax internal battery EN54 is a rechargeable Li‑ion backup battery designed to provide up to 24 hours of emergency power for compatible Ajax alarm and safety devices that require EN54‑compliant backup. With a nominal voltage of 7.4 V and a capacity of 5 Ah, this internal battery supports continuous operation during mains outages and maintains alarm signaling, event logging and monitored system status until primary power is restored or a controlled shutdown is performed.

Advantages

The battery offers a compact, factory‑tested Li‑ion construction that delivers stable voltage output and a high energy density for prolonged backup time relative to weight and size. Its 7.4 V nominal voltage and 5 Ah capacity are matched to the power demands of EN54‑compatible alarm modules, ensuring predictable discharge characteristics and reliable alarm transmission under load. Rechargeable chemistry reduces maintenance compared with single‑use cells and supports repeated charge/discharge cycles while maintaining consistent performance.

Подходит для

  • Backup power for Ajax alarm control panels and EN54‑compliant safety modules
  • Temporary power during mains failures to keep sensors and communicators active
  • Systems requiring a rechargeable internal battery with predictable runtime

Key specifications

  • Chemistry: Lithium‑ion (rechargeable)
  • Nominal voltage: 7.4 V
  • Rated capacity: 5 Ah
  • Intended function: Internal backup power for alarm and safety devices
  • Designed runtime: up to 24 hours under specified load conditions
  • Form factor: compact internal module suitable for compatible enclosures

How to use

Install the internal battery into the specified compartment of a compatible Ajax alarm or EN54‑compliant safety device following the manufacturer's installation instructions. Ensure connectors are fully seated and polarity is correct before closing the enclosure. Charge the battery via the device's integrated charging circuit; initial charging and periodic charging are handled automatically by the host unit. After installation, verify system status and battery charge level through the alarm system interface or monitoring tools to confirm proper integration.

Usage recommendations

Store and operate the battery within the temperature and humidity ranges specified by the host device documentation. To maximize service life, avoid long‑term storage in a fully discharged or fully charged state; if storing for extended periods, keep the battery at approximately 40–60% charge and check charge level every few months. Replace the battery according to the alarm system maintenance schedule or when runtime degrades noticeably.
