Individually acknowledging troubles

When individual acknowledge is used, the tone-alert re-sounds when the condition clears. Individual acknowledge must be selected if the
panel is providing proprietary receiving service in accordance with NFPA72. Follow these steps to use individual acknowledge.
1. Unlock and open the enclosure door. The alphanumeric display shows the trouble condition. For example:
2. Press the TROUBLE ACK key. Repeat this step and read the reports. You need to do this for each trouble event. The following
occurs:
- The tone-alert silences and the LED glows steady.
- The alphanumeric display shows the area and type of problem, as shown below.
3. Read the alphanumeric display. Investigate the trouble to determine its cause. Restore or replace defective device (switch, wire,
notification appliance, etc.) in accordance with the manufacturer's instructions.
When the trouble clears, the TROUBLE LED flashes and the tone-alert sounds steadily.
4. Press the TROUBLE ACK key. The display shows the system status. Press the TROUBLE ACK key again. After a delay, the display
shows that the system status is normal.

If the trouble doesn't clear

Normally, trouble points do not require acknowledgment of the cleared condition. If the system does not clear, read the display. If the
source of the trouble cannot be located, call your Simplex branch office to repair the system.

System Reset Key

Some troubles latch until they are reset manually, or are reset by pressing the SYSTEM RESET key. Try pressing the SYSTEM RESET key if
the trouble is any one of the following:
• Style D initiating device circuit trouble.
• City Circuit trouble.
• 24 Point I/O trouble.
If pressing the SYSTEM RESET key does not clear the trouble, or if the trouble toggles (clears and then reappears), you may choose to
either disconnect the device or to disable the point, using the procedure outlined in the next section.
4.7.2

Disabling a point with a trouble condition

Keep the following in mind when disabling points:
• Disabling a point causes the point to NOT report alarm conditions or other status changes. A point should not be disabled unless it
is clearly understood that fire detection or security for the area of the building covered by that point would be lost. Appropriate steps
must be taken to provide alternate means of protecting the area of the building covered by the disabled point.
• Repair or replace the failed device or circuit as soon as possible. Once repaired, the disabled point should be enabled as soon as
possible.
1. Press the TROUBLE ACK key to display the point's information on the alphanumeric display. For example:
