System 3505 Prism LX

System 3505 Prism LX

The System 3505 Prism LX™ is a highly integrated alarm monitoring system that uses state-of-the-art components and circuitry to continuously monitor and display the status of all connected alarms. When an alarm condition occurs, the System 3505 Prism LX™ presents it to the operating personnel via a programmable System 3505 Prism LX™ Monitoring System audible alarm, color graphic display and a permanent printed record on the thermal paper tape. The System 3505 Prism LX™ can monitor up to 500 active alarm points simultaneously, and in any combination of multiplex, telegraph / McCullough codes, direct-wire, digital dialer, network, polling radio, and serial input alarm signals, as well as Ethernet utilizing the AlarmLan. Options can be tailored to your installation’s precise needs.

System 3505 Prism LX™ Enhancements

Remote Annunciator offers an interactive audio/visual display of System 3505 Prism LX™ activity at remote locations. Multiple Remote Annunciators can be added to the system, distributing filtered information to many locations. Remote Annunciator options include automatic Text-2-Cell & E-mail notification. See Cut sheet 750581.

Digitize AlarmLan™ option allows the System 3505 Prism LX™ to communicate with equipment practically anywhere in the world via Ethernet. Multiple Prism LX units can be connected in a LAN / WAN configuration and each Prism LX unit becomes an Alarm Server.

Test Mode Option masks user specified alarms by alarm point, groups of alarm points, or buildings, for a user specified time not to exceed 8 hours.
