Replacing The Security Controller Base Assembly - Honeywell SEC-H-600 Installation Instructions Manual

SEC-H-600 SECURITY CONTROLLER

REPLACING THE SECURITY CONTROLLER BASE ASSEMBLY

CAUTION
Before handling circuit boards, discharge any accumulated static by touching the metal surface of the Security
Controller. For details, see "Static Discharge Precautions," page 9.
To replace the Security Controller base assembly (SEC-H-600) in the field, proceed as follows:
1. Using the backup feature within the Security Appliance (or the appropriate NiagaraAX software tool), back up the Security
Controller's configuration to your PC.
2. Disconnect the Backup Battery.
3. Remove primary power to the Security Controller by de-energizing the SEC-ENC-H-1 or SEC-ENC-H-2 enclosure power
supply. The unit should power down automatically.
4. Remove power to loads switched through its relay outputs, such as door strikes.
5. Note positions of all communications and other wiring cables going to the Security Controller. If necessary, label connec-
tors to avoid mis-connection later, after the Security Controller is replaced.
6. Unplug all Ethernet, serial, modem, and security I/O connectors from the Security Controller.
NOTE:Removal of the larger screw terminal connectors from the circuit board pins may require gentle prying between the
connector and the circuit board. When removing, grasp the connector firmly at both ends, and pull out from the circuit
board. See "About Screw Terminal Connectors," page 12.
7. Unplug the 6-position end-connector plug from the Security Controller, if present.
8. Remove the screws in the two mounting tabs, and slide the Security Controller away from the integral power supply of the
SEC-ENC-H-1 or SEC-ENC-H-2 enclosure.
9. Remove the Security Controller from the DIN rail (see Fig. 3 on page 11).
10. Remove the cover from the old Security Controller (see "Removing and Replacing the Cover," page 11).
Note the position of installed Option Cards, if any. You must transfer them to the replacement unit.
11. Remove the option cards from the old Security Controller and install them into the replacement SEC-H-600, if applicable.
12. Mount the replacement SEC-H-600 controller on the DIN rail, plugging it into the enclosure's power supply. See Fig. 3 on
page 11. Re-secure by fastening the screws into the two mounting tabs.
13. Reconnect the Grounding wire to the grounding connector lug.
14. Reinstall the other security I/O screw terminal connectors onto the appropriate circuit board pins, including the Reader
Inputs, Supervised Inputs, Relay Outputs, and Digital Inputs.
15. Reconnect any Ethernet, serial, modem connections to the Security Controller.
16. Reconnect the 6-position end-connector plug into the Security Controller.
17. Restore power to loads switched through relay outputs, turn the devices back on, or reconnect power to them.
18. Reconnect the Backup Battery.
19. Restore power to the Security Controller.
It should boot up as a new unit (see "Check the Status LEDs," page 27).
20. For software re-configuration details, see the WEBs-AX Security User's Guide.
