CAN Annunciator
Illustration 1 g02278719The OCP CAN annunciator serves to display system alarm conditions and status indications. The CAN annunciator has been designed for use on the OCP accessory CAN data link. The annunciator may be used in either local or remote applications, providing customers with enhanced site flexibility.In local application, the CAN annunciator may be mounted on the package generator set with the OCP to provide a complete package-mounted monitoring solution.The annunciator may also be mounted locally on the package generator set or remotely up to 800 feet on the Accessory CAN data link.A maximum of four CAN annunciators can be mounted locally or remotely and connected to the accessory CAN 2 data link.Features
Sixteen (16) LED pairs for annunciation of up to 32 system events
An additional pair of LEDs provides status indication of the CAN data link connection
Can annunciate alarm conditions received from any module on the CAN data link
Alarm horn with lamp test and alarm acknowledge pushbuttons
Can be mounted either locally on the package generator set or remotely (up to 244 m (800 ft)) on the accessory CAN data linkSpecifications
