Fire-Lite Alarms MS-9200 Technical Manual page 66

The information displayed in the first line in the previous example provides the following information:
• The type of event - in this example TRBL indicates Device Trouble.
• The Specific Device Trouble - the # symbol will be replaced by a digit representing a specific trouble
condition. (Refer to the list of Specific Device Troubles below).
• Type of device - in this example MONITOR indicates monitor module.
• Point type and address - in this example M01 indicates monitor module assigned to address 01.
The information displayed in the second line in the previous example provides the following information:
• <ADJ> - user programmed adjective descriptor from library list or custom entry (five characters max.).
• <NOUN> - user programmed noun descriptor from library list or custom entry (ten characters max.).
• Zone - zone to which the point is assigned.
The # symbol in the display will be replaced by a digit that represents the Specific Device Troubles as listed below:
1 = Invalid Reply:
An Invalid Reply may be due to: (1) incorrect pulse width received from a module, (2) no answer from a
module due to either a complete device failure or removal from the SLC loop, or (3) an incorrect identifi-
cation code received, i.e. a monitor module replaced by a control module or vice-versa.
2 = Short Circuit Control Module:
A Short Circuit exists across a control module's Notification Appliance Circuit (NAC).
3 = Open Circuit Monitor/Control Module:
An Open Circuit exists on a control module's Notification Appliance Circuit (NAC) or the monitor
module's Initiating Device Circuit (IDC).
Pressing the Acknowledge switch will cause the piezo to silence and the System Trouble LED to go on steady.
This occurs regardless of the number of troubles, alarms and supervisory events active in the system (block
acknowledge). When Acknowledge is pressed, and at least one new alarm or trouble exists in the system, the
ACKNOWLEDGE message is sent to the printer and history file.
If the trouble clears, either before or after ACKNOWLEDGE, the CLEAR TROUBLE message is sent to the printer.
For example:
CLR TRBL_# SMOKE DET P01 <ADJ><NOUN> ZONE # TIME and DATE CLR TRBL_# SMOKE DET P01 <ADJ><NOUN> ZONE # TIME and DATE CLR TRBL_# SMOKE DET P01 <ADJ><NOUN> ZONE # TIME and DATE CLR TRBL_# SMOKE DET P01 <ADJ><NOUN> ZONE # TIME and DATE CLR TRBL_# SMOKE DET P01 <ADJ><NOUN> ZONE # TIME and DATE
If all troubles clear and there are no supervisory or fire conditions active in the system, the system returns to
normal operation status, and the SYSTEMS ALL NORMAL message is shown on the LCD display and stored in the
history and printer files. Trouble restore occurs even if the troubles were never acknowledged (auto restore).
If ALARM SILENCE is pressed when only troubles exist, it will have the same effect as ACKNOWLEDGE/STEP.
The ALARM SILENCE LED will not be illuminated unless there was also an alarm in the system.
If multiple trouble conditions exist in the system, they will be scrolled on the LCD display automatically at a three
second rate. If a combination of alarms, troubles and/or supervisory conditions occur in the system simulta-
neously, only the alarms are scrolled on the display . If the ACKNOWLEDGE/STEP key is pressed, the display
stops on the present item for one minute, or until the ACKNOWLEDGE/STEP key is pressed again. As the AC-
KNOWLEDGE/STEP key is pressed, the MS-9200 displays events in the following priority order:
