Description
The PC-359B call holding circuit board delivers essential latch functionality for remote stations within the NEM series Lamp Memory System. This circuit board facilitates the configuration of a speaker and a “Normally Open” call button as remote stations in scenarios where a traditional sub-station setup is not feasible. Given the NEM system’s impedance of 20 ohms, it is recommended to use a 20-ohm speaker, or alternatively, an 8-ohm speaker paired with an LT-1 matching transformer to ensure optimal performance.
