Consumers Security Group can supply your business with Underwriters Laboratories Certificates if required. The three main types of certificates are as follows:

A central station system is one in which the operation of electrical protection circuits and devices are signaled automatically to, recorded in, maintained and supervised from a central station having trained operators and runners (alarm investigators) in attendance at all times. Runners are dispatched to make an investigation of unauthorized entry or opening of protected properties from which signals are received. System arming and disarming is supervised by the central station.

A central station Certificate displays the following information about an alarm system.

• Type of system - premise, stockroom, safe, vault, night depository, automatic teller machine or holdup.
• Extent of protection - numbers 1, 2, 3 and 4; complete or partial.(Definitions can be found in UL 681. For example, extent 1 is the highest level of protection and extent 4 the lowest).
• Area covered/location - text that clarifies exactly what is protected by system.
• Alarm sounding device - none, inside, outside, or inside and outside.

• Monitoring location - the address of the monitoring station.
• Systems with no investigator response (for extent no. 4) - the party notified in case of alarm - may be law enforcement, subscriber or subscriber's agent.

A mercantile alarm system is one in which the operation of electrical protection circuits and devices activates an alarm sounding device inside and/or outside of the protected premises. A mercantile alarm system may or may not provide remote location transmitting equipment that will transmit a signal off premises. The operation of a mercantile alarm system is primarily under the control of the owner or others interested in the property to be protected.

Any supervision of system arming and disarming is not audited by UL. Alarm investigators are not required or audited by UL.
