MPC-6000 / MPC-7000 / RND-2 INSTALLATION, OPERATION AND MAINTENANCE MANUAL
Operation of the ACKNOWLEDGE button within 15 seconds will add a number of seconds (60-
180) to the PAS timer. If the ACKNOWLEDGE button is not operated within 15 seconds, the system and user outputs activate.
If the initiating device and the panel are reset before the PAS timer times out, the alarm sequence is aborted.
An alarm condition on a detector programmed for direct alarm response (such as the key switch on a manual station) will override the PAS timer and activate the outputs.
A point activated by a PRE-SIGNAL alarm device activates the alarm relay, alarm DACT, alarm LEDs and buzzers, and all user-programmed outputs normally, except NACs. Only presignal type NACs operate at this time. Pre-signal type NACs are for constantly attended central locations manned by trained building personnel.
Operation of the SYSTEM RESET button within the pre-programmed time (60-180 seconds) after initiation of the pre-signal prevents operation of the general alarm.
Failure to act within the pre-programmed time (60-180 seconds) will result in activation of the general alarm.
Receipt of a general alarm during the delay period immediately sounds the general alarm building NACs.
Do not reset the system until the alarm condition has been cleared. The LCD will indicate the area in which the alarm was detected. The detector or module associated with the device initiating the alarm will display a light indicating activation (if applicable).
When the alarm condition has been corrected, return the system to standby operation by pressing the SYSTEM RESET button.
Trouble Conditions
In case of a trouble condition, the system trouble LED and any programmed trouble LEDs activate (ON – pulsing), the LCD identifies the problem and the buzzer sounds (pulsing). Refer to the applicable section of the system manual to determine the probable cause of the trouble and the action to be taken.
When a trouble has been noted, the buzzer may be silenced by pressing the ACKNOWLEDGE button. The trouble LEDs will change to ON - steady. If the trouble has not been corrected when the trouble resound reminder timer expires, the trouble display reverts to its original condition and the buzzer resounds (pulsing).
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 require a system reset to restore the control unit.
