JK300A / JK300/2 Monitor Call Interface

The JK300A Monitor Call Interface is for use in applications where a simple interface is needed to connect the 'monitor' input of an IR300 series or IR400-P5 series station to an external dry contact closure. The JK300A will accept a standard 1/4" phono type plug input and will register a 'MONITOR' call, if plug is removed, or if the 'normally open' dry contact closure is activated (closed). A 1/4" 'dummy plug' is included for use when the monitor point is not connected to an external device. The JK300/2 Monitor Call Interface provides two (2) 1/4" jacks and two (2) dummy plugs.

The JK300A is typically used with the HC345C, NC300, NC300II and TC400-P5 systems. The JK300A and JK300/2 are not designed for use in a shower or 'moist' environment.
