High efficiency cost effective power supply ideal for use in Fire and Access Control applications, where electromagnet door retainers on Fire doors need to be powered and controlled.
A 24V dc output is provided for direct connection to the door retainer electromagnet whilst versatile remote control inputs permit flexible connection to various remote control sources to switch off the output in the event of a fire alarm or other command:
The three input options for the remote control of the output are as follows:
- Removal of an external 24V dc supply (BS 7273 Compliant – See Typical Setup 1, page 3)
- Opening of a normally closed volt-free contact (See Typical Setup 2, page 3)
- Closing of a normally open volt-free contact
LED status indicators (internal) provide diagnostics showing the presence of a mains input or an output fuse failure. The products use energy efficient switch mode technology and have a universal mains supply input (90—264V ac).
Note this power supply should NOT be used for charging standby batteries.
