6 R-Series Remote Annunciators and Expanders Installation and Operation Guide
Installing annunciators and expanders
For correct operation, the annunciator must be configured with a unique address,
must have the correct baud rate setting, and must be in communication with the
FACP.
If you are installing a Remote Annunciator and Remote Expanders into RA-ENC2
or RA-ENC3 enclosures, you must install the expanders first. Refer to the
installation sheets for the enclosures for the correct sequence of steps.
If you are installing Remote Annunciators and Remote Expanders using separate
electrical boxes, the wire runs between the boxes must be enclosed in conduit.
If you are installing a remote key switch, the switch must be located within the
enclosure or within 3 ft. (0.9 m) of the enclosure with the cabling installed in
conduit or equivalent protection against mechanical injury.
To install an annunciator:
1. Secure the mounting ring to the electrical box, as shown in Figure 4.
2. Use the DIP switch to set the correct address and baud rate. See Table 3 on
page 5 for DIP switch settings.
3. Connect the control panel annunciator circuit to the appropriate annunciator
terminals. See Figure 5, Figure 6, Figure 7, and Figure 8.
Tip: Leave enough wire to remove and position the annunciator when setting
the DIP switch.
4. Attach the expander cable to the annunciator, if applicable. See Figure 9.
5. Attach the remote key switch wiring to the annunciator, if applicable. See
Figure 8.
6. Tilt the annunciator up and slide the mounting slot onto the top flange of the
mounting ring, as shown in Figure 4.
7. Tilt the annunciator down and push the bottom of the annunciator over the
stud-nut.
8. Secure the bottom of the annunciator to the mounting ring using the captive
screw.
9. Cover the screw hole with the product label plate.
To install an expander:
1. Complete and insert the zone card (labeling sheet) into the expander.
2. Secure the mounting ring to the electrical box, as shown in Figure 4.
3. Connect the expander cable to the expander. Attach an expander cable for
interconnection to a second expander, if applicable. See Figure 9.
