Pulsar EN54C-LCD series power supply unit Power supplies for fire alarm systems 27,6 V DC Remote monitoring (options). PSU has been adjusted to operate in a system that requires a remote control of parameters in a monitoring centre. Implementation of this function is possible upon installation of an additional communication interface. Data are transmitted using the modbus protocol, and their exchange may be effected through a RS485 bus or through the Ethernet. ETHERNET network communication.

Pulsar EN54C-LCD series power supply unit Power supplies for fire alarm systems 27,6 V DC Fuse modules EN54C-LB4 and EN54C-LB8. Fuse modules EN54C-LB4 and EN54C-LB8 allow to connect 4 or 8 receivers to the PSU. Output state is indicated by green LEDs. Blown fuse signal is transmitted to the input of collective failure EXTi (ALARM) and saved in the internal memory of PSU. Relay output of PSU fuse strip can be used for remote control, e.g. external optical indication.
