Simplex 4008 Fire Alarm Control Panel Control Panel (needs programming)
This Simplex 4008 fire alarm control panel is functional other than the annunciator on the front panel cover. Otherwise, it will need a lot of re programming and potential service in order to get back to a fully normal functioning status. I personally don't know what I am doing so I am sure someone with basic knowledge regarding Simplex fire alarm panels will know exactly what to do. Also, the NAC circuit has been in trouble even with a resistor, so there could be an issue there. Otherwise, it is a great fire alarm panel to have.
