Power Supply Systems

Product Details:

The external power supply unit DB-2, built into a powder-coated metal housing, offers space for up to two 12 V / 45 Ah batteries. A connection to the fire alarm control panels IQ8Control and FlexES Control can be made directly via the optional adapter board (part no. HLSPS-ADPTR) with an esserbus® alarm tranponder (part no. 808623). Alternatively, a relay output with floating changeover contact is available for the transmission of faults (mains, battery and collective faults as well as earth fault). DB-2 offers external LED display for operation and collective fault in the lockable front door, internal LEDs for detailed detection of emergency power operation, individual monitoring of battery failure, ground fault, deep battery discharge as well as system errors and mains failure. The settings for battery capacities and combinations are made via DIP switches on the base board of the DB-2.

• Part-No.: HLSPS-DB2

Product Details:

External power supply in a compact metal housing for holding up to two 12 V / 17 Ah batteries for use in fire and voice alarm systems. Up to two 12 V / 38 Ah can be connected and charged via the supplied battery housing. The power supply allows an uninterruptible power supply.

Two potential-free relay outputs are available for the transmission of faults (common fault, battery fault). External LED display for operation and common fault on the front door.

• Part-No.: F-PSU-2405 
• Approval: VdS

• Two potential-free relay outputs
• Single monitoring of the batteries for emergency power supply
• Compliant with EN 54-4 (A2)

Product Details:

The converter provides a galvanically isolated 12 V power supply for a detector for special applications. The input voltage is 12 V, and it is supplied from the fire alarm control panel or from an external PSU. The module can be integrated into the 120240, 788600, 788601, 788603.10, 788650.10, or 788651.10 enclosures.

When planning the project, please pay attention to primary (12 V) current drain in case of a mains failure.
