National Industrial Security System Listing Evaluation
Listing Evaluation
The UL Listing evaluation includes examination of 2 alarm systems.
These systems must be installed in compliance with UL681, Installation and Classification of
Burglar and Holdup Alarm Systems.


1 of these systems must be an Extent 3 closed area, alarmed room, or strong room
1 must be an Extent Complete alarmed container, safe, or vault
These systems must also be maintained, monitored and receive guard response in accordance
with UL2050, The Standard for National Industrial Security Systems
Finally, the monitoring facility, means of record keeping, and investigation procedures must
comply with the requirements of UL2050, National Industrial Security Systems.
With respect to signal handling, an important part of the UL evaluation is to determine if the
personnel responsible for monitoring can perform in accordance with UL2050. To evaluate this
capability, we will conduct a service test by creating signals that are sent to the monitoring
facility. These tests will be conducted from the alarmed locations submitted for our review. In
addition, we will audit the records maintained on these alarmed areas to determine if openings
and closings are made in accordance with UL2050.
Standards
UL681 is available for purchase from COMM 2000, at www.comm-2000.com or 888-853-3503.

If a receiver cannot tolerate a 30 second loss of power or if an automation system is used, then 15 minutes
of battery power is required in addition to the two generators.
The specific details for each external power supply must be captured on following pages. External power
supplies may be chargers and batteries, a UPS, or generators. Secondary power supplies that are internal to
a receiver need only to be examined to determine they provide adequate battery capacity based on the
supply configuration indicated above.
Describe how the Secondary Power Supply is configured. If batteries are used as part of the secondary power
supply, note if the charging source in within the receivers or external to them. Also explain what each source
(Battery charger, UPS or generator) is supplying.
