De-Registering RHUs and RDUs
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 that
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.
Note that after an RHU or RDU has been de-registered, it
may not be re-registered until the MCP first sends it its con-
figuration data. Also, an RHU or RDU can be de-registered
whether or not it is communicating with the MCP. After it is
de-registered, any troubles created by that unit in the MCPs
"System Active Event List" will be removed.
If the device that is de-registered is still in communication
with the MCP, the MCP will generate a trouble event "Com-
municating with unregistered device."
De-registering an RHU will cause any RDU previously as-
signed to that RHU to become unassigned. Manual Re-
lease and Abort switches attached to such unassigned
RDUs will generate Trouble signals.

Optional Relay Boards
Optional Relay Boards can be mounted on the MCP and
each RHU on the system. ORBs provide 5 Programmable
Form C Relays, each of which can be configured to re-
spond to any one of several local events:
Once the Optional Relay Board is installed and the con-
nector is plugged in, configuration parameters should be
entered through the menu system as described below:
1.
Press the down arrow key to access the Main Menu.
2.
Select Set.
3.
Scroll down the menu and select Set Opt Rel Act St.
4.
Use the up and down arrows in the first field to scroll
through the list of units. When the relay that needs to
be edited is displayed, press ACCEPT.
Note:
The default factory configuration for the ORB Re-
lays is “Rel#X No Active Set” i.e., there is no acti-
vation set for Relay #X. There are two items for
each relay: an Activation state and a De-activation
state.
5.
To set the Activation state for relay #1, move the X to
the Change field and press the down arrow key to Rel
#1.
6.
With the X in the Sel (Select) field, use the up and down
arrows to scroll through and select one of the following
Activation states for that Relay:
a.
Local Indecisive (or First Stage) alarm condition
b.
Local Pre-Discharge condition
c.
Local Discharge condition
d.
Local Manual release condition
e.
Local Waterflow condition
f.
Local Supervisory condition
g.
Local Trouble condition
h.
Local Abort condition
i.
No Activation (the relay is effectively disabled)
7.
Select OK to save the changes. When configuring pa-
rameters for the Remote Hazard Unit, the change is
also sent to the unit. The change is accepted when the
message confirmation message is displayed.
De-activation states automatically mirror the Activation
states. For instance, an Activation state of “Set on Trouble”
will result in a De-activation state of “Unset Trouble Off” in
all but the following Activation states:
1.
The Activation state of “Set on Indecisive Alarm”
may have the deactivation states of either “Unset
Decisive Alarm Off” OR “Unset at Silence”
2.
The Activation state of “Set on Decisive Alarm” may
have the deactivation states of either “Unset Deci-
sive Alarm Off” OR “Unset at Silence”
If an ORB is subsequently removed, a trouble will be shown.
This is removed by setting all the activation states to “No
Activation”.

Configuring Device Tag Names
RHUs and RDUs are commonly referred to in the Display
and logs by their addresses, for example, RHU #7 or
RDU#12. However, these units can be assigned Tag Names
for easier identification by using the following procedure:
1.
Press the down arrow key to access the Main Menu.
2.
Select SET.
3.
Scroll down and select "Set Device Tag."
4.
Use the up and down arrow keys to display the unit to
change.
5.
Move the X under Change and press ACCEPT.
6.
Starting in the left-most field, use the up and down ar-
row to select a character. Then proceed to the second
field and choose the next letter. The Tag Name can be
a maximum of seven (7) characters.
7.
Select OK. A confirmation message displays. Press
ACCEPT.
