Operating principle
EN54 Internal Battery (24h) and EN54 Internal Battery (72h) are internal batteries used as a backup power source for the Ajax EN54 CIE or range extender.
Selecting an installation site
The battery must be installed only in the EN54 Fire Hub Jeweller or EN54 Fire ReX Jeweller enclosure. When selecting the CIE or range extender location, consider the factors that affect the battery operation:
- Operating temperature range.
- Permissible humidity level.
Consider the placement recommendations when designing your Ajax system. Only professionals must design and install the system. The list of recommended Ajax partners is available here.
Where not to install the device with EN54 Internal Battery
- In places with high temperature. For example, near heat sources, such as radiators, heaters, direct sunlight, etc. High temperature can cause battery overheating, rapid self-discharge, damage to its components, explosion, or fire.
- In places with high humidity. Moisture can corrode the contacts or cause a short circuit.
- Near flammable materials. Never place the battery near flammable liquids or materials. Doing so increases the risk of fire or explosion, especially if a short circuit occurs.
Installation
Before installing the battery, ensure that you have selected the optimal CIE or range extender location and read the EN54 Fire Hub Jeweller and EN54 Fire ReX Jeweller user manuals. The battery can be installed in the CIE or range extender, even if an external power supply is connected.
During Ajax system installation and operation, follow the rules and requirements of regulatory legal acts on electrical safety.
Do not dismantle, open, or shred secondary cells or batteries. Do not insert your fingers, hands, or foreign objects in any battery gaps or openings, such as vents, terminals, etc.
