Replacing The Security Controller Base Assembly - Honeywell SEC-H-602 Manual

SEC-H-602 AND SEC-H-616 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 8.
To replace the Security Controller base assembly in
the field, proceed as follows:
1. Using the backup feature within the Security Appli-
ance (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/U or SEC-ENC-H-
2/U 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 wir-
ing cables going to the Security Controller. If neces-
sary, label connectors 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 con-
nectors from the circuit board pins may
require gentle prying between the connec-
tor and the circuit board. When removing,
grasp the connector firmly at both ends,
31-00012—03
and pull out from the circuit board. See
"About Screw Terminal Connectors," page
11.
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/U or SEC-ENC-
H-2/U enclosure.
9. Remove the Security Controller from the DIN rail
(see Fig. 3 on page 10).
10. Remove the cover from the old Security Controller
(see "Removing and Replacing the Cover," page
10).
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 Con-
troller and install them into the replacement Security
Controller, if applicable.
12. Mount the replacement Security Controller on the
DIN rail, plugging it into the enclosure's power sup-
ply. See Fig. 3 on page 10. 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 con-
nectors onto the appropriate circuit board pins,
including the Reader Inputs, Supervised Inputs,
Relay Outputs, and Digital Inputs.
15. Reconnect any Ethernet, serial, modem connec-
tions to the Security Controller.
16. Reconnect the 6-position end-connector plug into
the Security Controller.
17. Restore power to loads switched through relay out-
puts, 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 Sta-
tus LEDs," page 24).
20. For software re-configuration details, see the
WEBs-AX Security User's Guide.
