Product overview

The STX2410-E is a fully featured EN54-4 approved power supply ideal for use in fire system applications. It features intelligent battery charging, monitoring and signaling. Regulated 27.6 VDC output will source up to 10 A into the load as well as providing up to 0.7 A for charging the standby batteries. The power supply output features electronic short circuit protection under both mains and standby battery operation. Maximum battery life is assured through continuous active battery monitoring and a three stage charger, comprising bulk, absorb and temperature compensated final float phase depending upon battery condition. Once fully charged the product operates in Eco power saving mode, whereby the batteries are charged for 4 hours in every 24 hour period while still being continuously monitored. This reduces wasted energy in charging already fully charged batteries and extends their working life. Deep discharge protection prevents premature battery failure when operating from standby for extended periods.

Installer Friendly

A STX2410-E power supply is supplied in a self-contained, wall mount housing that can also house up to two 17 Ah batteries (not included). The housing features a center keyhole on the back for initial fixing to the wall, which is supported by 4 additional mounting holes. A potential-free contact is used to signal faults due to output failure, battery fault, charger fault or internal fault. A second potential-free contact signals the loss of mains power. These ensure any fault conditions are reported to the monitoring equipment, and that appropriate action is taken in the event of loss of mains power. The battery charging circuit is energized only when a battery is correctly connected and the battery voltage is greater than 14 V. In addition there is an RS232 serial interface that can provide diagnostic and fault reporting information to supervisory systems.

Key features:

  • Approved to EN54-4 / CPR
  • Up to 10 A current to load at 27.6 VDC nominal regulated output
  • Self contained box houses up to two 17 Ah batteries with intelligent load enhancement
  • Deep battery discharge protection
