Standby ConditionIn normal standby operation, the green AC POWER ON LED should be illuminated and no other indicatoroperating. The display will show the system name, “System Normal” announcement and the current date,day, and time.B. Alarm Condition1) Normal Alarmsa) In case of alarm, the system alarm LED will operate in a flashing mode and the buzzer will sound.Local audible and visual signals and remote alarm signals will operate, and the LCD panel display willindicate the zone or point initiating the alarm.b) On receipt of an alarm, proceed in accordance with the established emergency plan. Assure that allpersonnel are accounted for, and notify the Fire Department.c) To silence the audible after evacuation, where permitted by the codes and control unit programming,press ALARM SILENCE. The alarm audible will be silenced, the alarm silence LED will beilluminated and a system trouble indicated. Operating the ACKNOWLEDGE button will silence thelocal buzzer and change the LED alarm indicator from flashing to steady.2) Waterflow AlarmsAlarms detected on zones designated “waterflow” indicate sprinkler operation and the audible alarmscannot be silenced in this condition. Operation of alarm silence will produce no effect.3) Positive Alarm Sequence (PAS)a) Activation of a point programmed for PAS, including two-stage manual stations, activates the AlarmLED, display and buzzer (pulsing), but delays all other outputs (system and user) for 15 seconds.b) Operation of the ACKNOWLEDGE button within 15 seconds will add 165 seconds to the timer value,to make the total delay 180 seconds.c) If an ALARM SILENCE button is pressed or the sensor returns to a normal reading before theextended PAS delay time, the alarm sequence is aborted.d) An alarm condition on a sensor programmed for direct alarm response (such as the key switch on amanual station) will over-ride the PAS timer and activate the outputs.4) Pre-Signala) A point activated by a PRE-SIGNAL alarm activates the alarm relay, alarm DACT, alarm LEDs andbuzzers, and all user programmed outputs normally, but does not activate any NACs.b) Operation of the ALARM SILENCE button less than 180 seconds after initiation of the alarm preventsoperation of the NACs.c) Failure to act within 180 seconds will result in activation of the NACs.d) Receipt of another pre-signal or standard alarm during the delay period immediately sounds theNACs.e) A SYSTEM RESET is required to return the zone and input point to normal, whether or not the NACswere activated.NOTE: Do not reset the system until the alarm condition has been cleared. The LCD display on the willindicate the area in which the alarm was detected. The detector initiating the alarm will display a light. Ifmore than one zone is in alarm, the last zone to be alarmed will be indicated on the display. |
