6 ALARM CONDITIONS
Under alarm conditions the panel is operated from the buttons located on the main
section of the panel. These can be seen through the inspection window.
When a detector zone is in alarm, the red alarm LED will be flashing and the panel
buzzer will be sounding. To silence the local buzzer the alarm needs to be
acknowledged.
6.1 ACKNOWLEDGING ALARMS
To acknowledge alarms use the following procedure:
STEP 1 Open the panel door. The bell isolated light illuminates because the door
switch has operated which has silenced the alarm bell outside the
building.
While the door is opened the alarm light continues flashing and the buzzer
still sounds until all alarms are acknowledged.
CAUTION
Do not touch the keypad on the right of the panel as this is for the
use of technical staff only.
STEP 2 Read the displayed alarm message.
- The top line of the display is showing location and details of the first
alarm which operated.
Zn6 Level 4 East V-Smoke
Alarm # 1 of 3 11:27:00
- The left of the bottom line is showing the present state of the zone
or circuit. In the centre, it may be showing 1 of 1 which means
there is only one alarm, or it could be showing 1 of 2, or 1 of 3
depending on how many alarms there are. The time the alarm was
activated is displayed on the right.
