The system shall not be installed in the fail-secure mode unless permitted by the local authority having jurisdiction, and it shall not interfere with the operation of Listed panic hardware. The use of panicUL UL has not evaluated the use of panic hardware.
For proprietary burglary system use, all status changes at the protected premise must be programmed to cause both an audible and a visual annunciation at the central receiving station, and an . Andgment acknowledgment signal and local annunciation must be programmed from the central receiving station to the protected premise.

For burglary use, all status changes at the protected premise must be programmed to cause both an audible and a visual annunciation at the central receiving station, and an acknowledgement acknowledgment signal and local annunciation must be programmed from the central receiving station to the protected premise.
If the user assigns Alarm Priority levels are assigned by the user, then the following priority must be assigned given for UL applications:
Fire alarm and industrial supervision where involve a risk of injury to persons, or damage to or destruction of property may be involved.
Hold-up or panic alarm.
Burglar alarm.
Watchman tour.
Fire-alarm supervision.
Burglar-alarm supervision.
Industrial supervision where a risk of injury to persons, or damage to or destruction of property will not be involved.
Other supervisory services.
Items (b) and (c) may have equal priority; items (e) and (f) may have equal priority; importance, and items (g) and (h) may have equal priorityemphasis.
The Alarm Stacking feature is not to be used for UL applications.
The Return to Normal feature is not to be used for UL applications.

Central Supervisory Station
The data processing equipment and office appliance and business equipment used as central supervisory station equipment shall be Listed under Office Appliances and Business Equipment (UL 114), or Information Processing and Business Equipment (UL 478), or Part 1: General Requirements of Information Technology Equipment (UL 60950-1).
A redundant server configuration should be employed, where the servers and workstations are networked via a dedicated Ethernet LAN. The network interfaces the protected premise units through an Xbox with a serial-to-Ethernet converter , or a SNIB2.
A “panel logged off” event may be a compromise attempt on the system.
Supply line transient protection complying with the Standard for Transient Voltage Surge Suppressors (UL 1449), with a maximum marked rating of 330 V, shall be used on Central Monitoring Station equipment.
If Suppose the XBox is not installed in the Central Monitoring Station, . In that case the signal line transient protection complying with the Standard for Protectors for Data communications and Fire Alarm Circuits (UL 497B) with a maximum marked rating of 50 V shall be used on communication circuits extending more than 25 feet from the computing systems.
Communication Secondary protectors for communication circuits shall protect communication circuits and network components connected to the telecommunications network shall be protected by secondary protectors for communication circuits. These protectors shall comply with the Standard for Secondary Protectors for Communication Circuits, UL 497A. These protectors shall be used only in on the protected side of the telecommunications network.
The Central Monitoring Station Equipment shall be installed in a temperature-controlled environment. A temperature-controlled environment is defined as one that can be maintained between 13–35°C (55–95°F) by the HVAC system. Twenty-four hours of standby power shall be provided for the HVAC system. The standby power for the HVAC system may be supplied by an engine-driven generator alone; a standby battery is not required to be used.
In addition to the main power supply and secondary power supply that are required to be provided at the Central Supervisory Station, the system shall be provided with an uninterruptible power supply (UPS) with sufficient capacity to operate the computer equipment for a minimum of 15 minutes. If more than 15 minutes is required for the secondary power supply to supply the UPS input power, the UPS shall be capable of providing input power for at least that amount of time.
The UPS shall comply with the Standard for Uninterruptible Power Supply Equipment (UL 1778) or the Standard for Fire Protective signaling Devices (UL 1481).
To perform maintenance and repair service, a means for disconnecting the input to the UPS while maintaining continuity of power to the automation system shall be provided.
The alarm system’s network settings shall be designed such so that the maximum time lapse from the initiation of an initiating a device circuit until it is annunciated at the Central Supervising Station shall not exceed 90 seconds.
The alarm system’s network settings shall be designed such that the maximum time for the Central Supervising Station to annunciate a single break, single ground, wire-to-wire short, loss of signal, or any combination of these, shall not exceed 200 seconds.
The alarm system configuration shall be designed such that the number of signals on a single channel shall be limited to 1000.
