MPC-6000 / MPC-7000 / RND-2 INSTALLATION, OPERATION AND MAINTENANCE MANUAL
25
If the control unit is programmed for “trouble acknowledge required”, when the indicated trouble
condition has been cleared, the system reverts to standby condition only after the ACKNOWLEDGE
button is pressed.
Some trouble conditions are latching troubles that require a system reset to restore the
control unit to supervisory mode.
Supervisory Conditions
In case of a supervisory condition, the system supervisory LED activates (ON – flashing) and the
sounder activates (ON – pulsing).
When the supervisory has been noted, pressing the ACKNOWLEDGE button will silence the buzzer
and change the supervisory LED to steady ON. If the panel is configured for Supv/Trouble Resound
Reminder and the supervisory condition is not corrected and the Supv/Trouble Resound Reminder
timer has elapsed, the panel will re-annunciate the supervisory condition.
The releasing zone will indicate a supervisory condition when it is disabled.
Detector Pre-Alarm Conditions
A pre-alarm condition is annunciated by pre-alarm LEDs and buzzers on the control unit and LCD
Annunciators and Remote Processors. The LEDs flash and buzzers are on steady until acknowledgment.
Acknowledging the pre-alarm condition puts LEDs on steady and buzzers off.
If pre-alarm has been acknowledged and the system restores to normal, the condition clears.
Fan Restart
If the fan restart feature is implemented, the input keyswitch (Independent Fan Restart procedure) with
fan restart usage must be initiated to deactivate the hold-thru reset output. A supervisory condition will
be annunciated that will clear when the keyswitch is restored to its standby state.
Fan restart can also be initiated from the front panel—user level. If fan restart is initiated from the panel
(Global Fan Restart procedure), all outputs with hold-thru reset output type will immediately deactivate.
If a Global Fan Restart procedure is initiated, precaution must be taken to prevent physical
damage to the fans, dampers, air ducts and other equipment. For example, staggering fan
activation to avoid power surges and verifying that dampers are opened before the fan
activates to prevent damage to the air ducts. These parameters must be monitored and
controlled by another method/technique that is not discussed in this manual.
Maintenance
In order to ensure continued safe and reliable operation of the fire alarm system, periodic inspection
and testing should be performed in accordance with applicable NFPA 72 standards.
If the system has remote connections to the Fire Department or other monitor, be sure to
disable the remote signals and/or notify the remote monitoring station before performing test
operations.
