Registering RHUs and RDUs
An RHU or RDU cannot be registered until the MCP has
first sent it configuration data. When a device is powered
up for the first time, it will detect its status as unregistered.
Resetting the MCP causes it to try and communicate with
every possible RHU and RDU. Any unregistered devices
that reply at this time will subsequently receive regular com-
munications from the MCP. The MCP will generate a trouble
event for every unregistered device that it is in communi-
cation with.
An unregistered RHU will monitor its hazard circuitry and
generate any alarm, supervisory or trouble events that it
detects. These events will only be shown locally, i.e., at the
individual RHU display and will not be reported to the MCP.
If the RHU detects a decisive alarm, it will not activate its
release output.
An unregistered RDU will display a message that it is un-
registered on its display. Any troubles detected by it will not
be reported to the MCP.
Perform the following steps to register RHUs and RDUs:
1.
Press the down arrow to display the Main Menu.
2.
Select Set.
3.
Select Register.
4.
Select either Register RHU or Register RDU.
5.
To select an RHU, with the X in the first field, press the
up and down arrow keys to display the RHU that needs
to be registered. Note: Units with pre-existing Alarms
cannot be registered.
6.
Select OK (move the X under OK and press ACCEPT).
A confirmation message “RHU#X Registered” or
“RDU#X Registered” will display. However, if the mes-
sage “Not registered. Failed to respond” is shown on
the display, check the network.
