System Reset
System Reset resets part or all of the system.
The green LED flashes when the system, or part of the system, can be reset. The
yellow LED flashes when there are conventional smoke detector circuits in alarm.
Press System Reset to reset the smoke detectors. The yellow LED also flashes if
the ground fault relay is activated. Press System Reset to deactivate the ground
fault relay to check for restores and additional ground faults. If ground faults
remain, the relay will be re-activated after 5 to 30 seconds.
Pressing System Reset with no LEDs flashing will operate any relays that are not
used by the system and deactivate any Aux Power outputs. The time they remain
open is determined by the Duration time programmed. If the Duration is 0, the
relay or Aux Power output will not operate.
Notes:
1.The system cannot
be reset until all circuits and devices are reset.
2.If both LEDs are flashing, the green LED function has precedence.
3.The green LED will remain flashing after System Reset is pressed
until addressable devices have had their LEDs reset.
Automatic
Alarm Signal
Cancel
(Second Stage
Inhibit)
Prevents the automatic operation of second stage operation. This applies only to
panels with ALERT or STAGED type bell systems. For ALERT systems, pressing
the Automatic Alarm Signal Cancel will prevent the panel from going into second
stage. For STAGED systems, it will prevent the system from going to the next
stage. Automatic Alarm Signal Cancel has no effect on an EVAC type bell system.
The green LED will flash when Automatic Alarm Signal Cancel is available, and the
yellow LED will flash when it has been activated.
Fire Drill
Activates all the bell circuits, both regular and coded, in Alert mode. Press a
second time to have all bell circuits sound in Evacuation mode. Press a third time
to end the Fire Drill. The red LED will flash while the Fire Drill is happening. The
Fire Drill cannot be performed if the bells are already activated, or if AC power is
off. The Fire Drill is automatically ended if an alarm condition occurs.
Relay
Disconnect
Causes the function relays and control modules to ignore any new alarms. Press
again to restore normal operation. The red LED will flash while active. If no relays
nor control modules can be disconnected, Relay Disconnect will do nothing. This
function can be set to Privilege Level 0 or 1.
Test Mode
Places panel into test mode. Press again to return to normal mode. The red LED
will flash while in test mode. This function can be set to Privilege Level 0 or 1. It
follows the Disconnect privilege level (set in MHI). During test mode, the remote
annunciator zone LEDs becomes non-latching for the zone(s) under test. The
common indicators, bells, and relays are not activated and no commands are sent
to other units and no signal is sent out of Port 3. Test signals can be archived or not
as required.
Before beginning testing, the circuits/devices to be tested must be selected. All
unselected circuits/devices will operate normally. Be sure that the panel is in test
mode. To select circuits/devices, select PROGRAM from the Main Menu on the
LCD. The arrow keys move the cursor and the <Enter> key selects the item.
Then select ADDRESSABLE, then TEST. Enter the device circuit and address for
each device to be tested. <Clear> will return to the previous menu.
When test mode is ended, all zones and devices selected for testing automatically
return to normal operation.
Note: There is no Ground Fault isolation while Test Mode is active.
