Alarm Annunciator (24 channels)

The DKM-0224 is a 24 channel, 144x144mm alarm annunciator, designed to be used in energy and automation systems. Optically isolated digital inputs are equipped with noise cancelling filters and are capable of operating smoothly in high electrical noise environments. The detection delay of inputs are adjustable between 2 and 500ms. The module features 3 relay outputs rated at 5Amp. Relays provide Horn, Bell and Internal Failure functions. An additional buzzer is provided inside the unit for audible alarms. The unit features ultra-bright, bicolor (red-green) led indicators. Alarms may be assigned to different priority levels in order to reduce confusion. Using front panel pushbuttons, alarms may be  acknowledged and reset, the unit tested.


  The configuration of the module is performed with DIP Switches placed on the back panel. Additional programming may be performed from the front panel or through programming software. The isolated RS-485 MODBUS RTU communication port is free from ground potential differences and allows safe transfer of measured parameters to automation and monitoring systems. It is possible to monitor the module and keep records with Datakom  Rainbow+ software. The supply input is isolated from other terminals. The module has two supply versions  being 19150V-DC or 85-305V-AC (88-400V-DC).  

FAST FLASH: at the first detection of the fault.

SLOW FLASH: activated when the ACK (alarm acknowledge) pushbutton is pressed and if the fault signal is still active.

STEADY ON: activated if the fault signal disappears at SLOW FLASH condition.

LED OFF: the alarm led turns off when RESET pushbutton is pressed and fault signal is not present.
