The 790-8ZB annunciator system comes completely wired for operation. Installation is a matter of connecting the sensors to the 790-8ZB. The system comes complete with power supply and a 7 ampere hour backup battery. Either normally open or normally closed sensor contacts can be used. The two conductors to each sensor should be 22 gauge AWG or heavier.

The display and bypass panel comprises eight lamps and push-button switches, a piezo audible sounder, a bypass inhibit keyswitch and a reset lamp and reset push-button switch. Each lamp represents one sensor and each lamp displays the status of a specific sensor. For example, when a door is open and remains open the lamp for that door illuminates and remains illuminated. When a door closes the lamp for that door extinguishes and remains extinguished as long as the door is closed. When a push-button is depressed, the lamp for that door constantly flashes indicating that door is out of service. The keyswitch on the panel is used to inhibit the bypass mode to prohibit unauthorized personnel from bypassing any of the doors. The audible piezo sounds when a door opens and remains sounding until the door is closed. A mode is possible when a door opens and closes again, the lamp remains illuminated and the audible piezo remains sounding until both are manually reset by attending personnel. When reset, the audible stops sounding and the lamp indicates the true status of the door.
