Read the applicable Honeywell installation instructions before work. Verify 05704-A-0123 and the installed System 57 5704F Control System configuration.
1Verify the complete 05704-A-0123 marking and its assigned System 57 5704F Control System position before work.
2Isolate the energy associated with System 57 rack before disconnecting 05704-A-0123.
3Protect the 05704-A-0123 connectors and electronic assembly using approved ESD controls.
4Record the as-found Four Channel Control Card connections and configured assignment before replacement.
5Confirm Hex Relay Interface Card matches the approved installation record for 05704-A-0123.
6Restore 05704-A-0123 under controlled conditions and review its model-specific diagnostics.
7Complete a documented functional test for fire-zone alarm relays before release.
Technical notes
Confirm the paired control and relay cards occupy the documented slots, verify each relay assignment and test fire, fault and inhibit outputs without bypassing active protection.
