CPI-800: Bi-Directional Contact Phone Interface   specsheet

Features: Bi-Directional Communication using Single phone Line Standard Dry Contact Inputs Form 'C' Relay Contact Outputs Uses Standard Class 'C' Voice Grade Line No Calibration or Setup Required Microprocessor Controlled for High Accuracy Power: 117 VAC 50/60 Hz (Optional 24 VDC) High Noise Rejection CSA and NRTL Approved (LR 51078)

Function:
The CPI-800 is a bi-directional telephone line communication system that exchanges the staus of 8 dry contact inputs between the master and remote unit. A complete system consists of one master station and one remote station each with 8 dry contact inputs and 8 'C' relay contact outputs.

Communication is in serial format using DTMF for greater reliability eliminating false transmissions. Maximum delay between contact closure and relay operation at the other station is 6 seconds and typically 3 seconds. A channel fail detection mechanism returns all relays to their de-energized position if communication is lost for 30 seconds or more.
