LED Indicator
External Input Signals
The PS-A’s RAS interface connector uses the following input signals.
•
General Purpose Input (DIN 2 bits)
This standard digital input is used for alarm detection in external devices. The input signal uses two bits.
The System Monitor property of the control panel or the API-DLL can be used to enable or disable this
feature, as well as designate what type of processing is to be performed once a signal is received. (Only
the “ON” state of the DIN circuit is detected. The “OFF” state of the DIN circuit cannot be monitored.)
•
Remote Reset Input (Available with DIN1 only)
This is the reset signal sent from an external device to the PS-A. When this signal is enabled, a forced
reset of the PS-A is performed.
The System Monitor property of the control panel or the API-DLL can be used to enable or disable this
feature.
