The EOL-32 is capable of monitoring a total of 32 end-of-line resistor, supervised alarm points with line resistance of up to 7,000 Ohms.  It provides the conversion of an analog alarm signal into the proper format to be processed by the System 3505 Prism LX. A ribbon cable of up to 25 feet connects the first EOL-32 with the System 3505 Prism LX. The System 3505 Prism LX can accommodate up to 15 additional EOL-32 interfaces, for a total of 512 alarm points. The second EOL-32 is connected to the first via a six-inch ribbon cable.  The third EOL-32 is connected to the second, and so on, up to 16 in a daisy-chain for a total of 512 inputs. The EOL-32 can be used in a chain of interfaces consisting of all EOLs or mixed with Reversed Polarity or Dry Contact inputs in groups of 32 zones.  

The EOL-32 interface can be ordered with 60 Hz filters.  

The EOL-32F is recommended for installations where the alarm lines travel via telephone company lines or over distances where induced AC is greater that 20 volts peak to peak. NFPA-72 compliant.
