Remote LED annunciator is available as an optional accessory (Part No. Guide 1551B can be used with any one of a variety of plug- bases. Therefore, connect all wiring following the instructions provided with the base that was for use with the 1551B. As Figure 1 indicates, are equipped with screw all connections. All wiring must conform to applicable local codes, and regulations. Verify that all sensor bases are installed and that wiring polarity is correct at each base. power from the loop before installing sensors.
