UL/ULC COMMERCIAL BURGLARY INSTALLATIONS continued...
Protection of the Control Unit:
The local control unit and the local power supply must be protected in one of the following ways:
- The control unit and audible alarm device must be in a protected area which is armed 24 hours a day.
- Each partition must arm the area protecting the control unit and the audible alarm device power supply. This may
require duplicate protection armed by each partition. Access to this protected area, without causing an alarm, will
require that all partitions be disarmed.
- In all cases described above, the protected area for the control unit must be programmed as not-bypassable
For installations employing packet switched (network) communications such as Cellular/Wi-Fi the following
recommendations shall be followed:
- Select the Internet Service Providers that have redundant servers/systems and Back-up power.
- Routers shall have Firewalls enabled and methods to identify and protect against "Denial of Service" attacks (i.e. via
"spoofing").
For UL Commercial Burglary applications the loss of communication with the monitoring station shall be treated as an alarm
condition by monitoring station personnel when the burglar alarm system is in the armed state, and as a trouble condition
while the system is disarmed. Packet switched data network (PSDN) interface equipment, manufactured by other than the
burglar alarm equipment manufacturer, that is not provided with the burglar alarm system and/or not required for the
processing of the signals shall be evaluated to the applicable requirements of the Standard for Information Technology
Equipment - Safety - Part 1: General Requirements, UL 60950-1, or the Standard for Audio/Video, Information and
Communication Technology Equipment - Part 1: Safety Requirements, UL 62368-1, as communication equipment. Any
network interface device which adds value or manipulates the original data packet such as changing transmissions formats,
adding encryption, and the like, shall comply with the applicable requirements noted in this standard.
