Modes of Operation

CHAPTER 3
The 411 digital communicator has five operational modes:

• Normal Mode

• Real Time Clock Mode
• Program Mode
• Troubleshoot Mode
• Default Mode
The operational mode for the digital communicator is Normal Mode. The operator is able to switch between any
modes of operation provided no alarm events are active in the system. It should be noted that the digital communica-
tor will not respond to input activations while in any mode except Normal Mode.
Access to any other Mode requires connection of the optional Fire-Watch 411 Series DACT Programmer which
consists of a keypad and display. Refer to Figure 3-1, "Programmer Keypad," on page 22:
3.1 Normal Mode
Normal Mode is the standard (default) mode of operation for the 411 digital communicator. The communicator
continuously monitors and reports to a central station, the status of the three input channels as well as the status of the
digital communicator itself. If no activity is detected on the three input channels (no shorts or opens) and the commu-
nicator is operating free of internal troubles, the digital communicator will display the following conditions:
Communication Fail LED is off
Onboard piezo sounder is off
The relay is in its normal deactivated state
Communicator is not transmitting to the Central Station
The 411 digital communicator transmits system status reports to a central station via the public switched telephone
network. Two supervised telephone line connections are made to interface the digital communicator to the telephone
lines. Both telephone lines are supervised by the 411 for proper voltage.
The 411 is capable of line seizure on both the primary and secondary telephone line interfaces. Any time the digital
communicator detects the necessity to call the Central Station, line seizure will disconnect any local premises phones
sharing the same telephone line. Sharing of phone lines, for fire systems, must be approved by the Local Authority
Having Jurisdiction. All transmissions to the Central Station will be sent over the Primary phone line. In the event of
a noisy or faulty phone line, transmissions will be sent over the backup Secondary phone line.
Transmission options exist to:
• send reports to the secondary phone number as backup only
• send reports to both the primary and secondary phone numbers
• send reports to the first available central station phone number
If 10 total attempts to communicate are unsuccessful, the digital communicator will turn on the Communication Fail
LED.
The 411 meets NFPA 72 requirements for Remote Station Protective Signaling Service and Central Station Signaling
Service reporting requirements for: (a) the type of signal, (b) condition and (c) location of the reporting premises.
See "Central Station Communications" on page 38, for additional information.
