The EN54 series is mainly used to operate external alarm devices in fire alarms where an SBF110:8 approved or EN54-4 certified battery backup is required. The EN54 family of battery backups has high flexibility, advanced alarm features, long spare operating times and high load handling. Battery backups in the EN54 series also perform battery tests to indicate when batteries need to be replaced. To maintain certificates, UPLUS 10+ Design Life AGM batteries shall be used. The EN54 has intelligent charging which means that when the batteries are fully charged, they will be put in electronic standby mode for up to 20 days or when the battery voltage has reached 26.7 V. By discharging the batteries in a controlled way and recharging them cyclically (instead of not using them), the service life is extended by up to 50%. The batteries automatically connect in less than 50 microseconds, if needed. The alarm devices should be able to be controlled and monitored for possible interruptions on the loop. We therefore recommend the optional Fire module 4 outputs to complement the battery backup. Mounting: EN54 can be mounted on wall or in 19″ racks, reversible brackets included. Installation and Deployment: Fixed Installation. Battery types: UPLUS 10+ Design Life AGM batteries. Connectable battery boxes: One to four battery boxes with space for two 45Ah batteries in each battery box. Typical uses:
- External alarm devices in fire alarms
Expected operating time in case of power failure:
