5.4 Fire Silence/Reset
During a fire alarm, exit the premises immediately. Do not enter the premises unless accompanied by the appropriate
Emergency Services' personnel, or after they have given the OK to enter. When it has been determined that there is no
fire, you may silence the horns/bells to allow further investigation of the devices that initiated the alarm, or you may reset
the system to return it to normal operation.
Before the [Reset] key is used, determine which smoke detector has alarmed so the monitoring company may
verify its operation.
The [Silence] key turns off the horns/bells, but does not reset the alarm status and does not return the tripped input to
normal service. Detectors that were tripped will stay in alarm and can be checked (usually by means of an LED on the
device) to see which detector caused the alarm. Once the detectors causing the alarm have been identified, the system
should be reset to return it to normal service.
The [Reset] key clears the system alarm status, and briefly turns off power to the detectors to reset them. This command
is required after any fire alarm affecting a point programmed for latching operation (which is the normal configuration).
5.5 System Trouble
A system trouble will be indicated by a short beep from the panel or keypad sounders every 10 seconds. The LCD will
display “SYSTEM TROUBLE”, followed by a description of the trouble condition. The system can diagnose and display a
variety of trouble conditions, including those affecting the input points, NAC circuits, power, battery, system grounding, and
internal operations of the fire control panel. Notify your installing company immediately if the system trouble message is
displayed.
The system trouble beep can be silenced with the [Silence] key. After problems have been remedied, [Reset] should be
pressed to clear the “SYSTEM TROUBLE” display.
5.6 Fire Safety
WARNING: No fire detection device or system should be considered 100% foolproof.
This fire alarm system can provide early warning of a developing fire. Such a system, however, does not ensure protection
against property damage or loss of life resulting from a fire. Any fire alarm system may fail to warn for any number of
reasons (e.g. smoke not reaching a detector that is behind a closed door).
When considering detectors for residential applications, refer to NFPA Standard 72, “The National Fire Alarm Code.” This
standard is available at a nominal cost from: The National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.
