Normally, trouble points do not require acknowledgment of the cleared condition. If the system
does not clear, read the display. Check for devices still in trouble (pull stations with their handles
down, smoke detectors with their LEDs ON). If the source of the trouble cannot be located, call
Simplex to repair the system.
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.
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:
2. Press the DISABLE key. The alphanumeric display shows the following message.
Note: XX represents the point to be disabled.
