 SCP Installation Manual


The SI-16 is a multi-device interface panel that has the ability to monitor high concentrations of inputs together with a low requirement for output control.  The SI-16 is capable of supporting 16 general purpose input circuits which can be individually set for normally-open or normally-closed operations and can be declared supervised and non-supervised. Individually configurable parameters can be set for sensitivity ranges, timing parameters and end-of-line resistance values.  Two programmable relay outputs can be configured for fail safe or fail secure operation, supporting "On", "Off", "Pulse", and "Repeating Pulse" commands.
