If you want to reset to default pulse times

* Change the module configuration (unplug a module temporarily) and cycle power

* Make sure the panel is powered off (circuit breaker or local disconnect)

* Unplug the power cable from the Power Supply Module that feeds high voltage to the DC Striker Modules

* Remove the output fuses from the module

* Set the multimeter to Diode Junction test mode

* Hold the red meter probe to the top power pin

* Check the top contact of each fuse holder on the module

** The voltage drop should be around 0.5 Volts - shorted outputs will be near 0 Volts (and fuse will be blown - do not replace)

** Return the module to Chime Master for replacement/rework if any measurement is less than 0.35 Volts
