Flex (600x224)


The Flex infrastructure monitor provides status and control of critical equipment at unattended remote sites. Located with the equipment to be monitored and controlled, the Flex communicates with the technician over the Public Switched Telephone Network (PSTN) or TCP/IP Ethernet.

System Features

The base Flex contains one IOModule and can monitor up to eight general-purpose inputs and one audio line. A fully expanded unit has eight additional IOModules and can monitor up to 72 general-purpose inputs and nine audio lines. The general-purpose inputs may be configured to operate in analog or digital modes, with a variety of characteristics. Each analog configured input has user-defined upper and lower limits, time delay, qualifier, and schedule and can measure voltages of 0-50 VDC. Each digitally configured input has user-defined active level, time delay, qualifier, and schedule parameters. The Flex automatically maintains a cumulative count of each input’s active time for the current and previous day. In addition, all enabled input active times are logged in the History at the end of each day. The status of any input can be determined by remote or local connection. The Flex can be user-programmed to generate major or minor alarms upon change of state of any monitored input, and alert the user via the programmed communication paths. The monitor will also notify the user when an input returns to normal state, if so programmed.

The basic Flex has two relay outputs, which may be programmed to function as normal, latching, or momentary, and can be remotely controlled or can respond autonomously as programmed by the user. The Flex may be expanded to 18 relay outputs.

Additional Flex features include input activity tests, scheduling of relay activation and alert calls, and the logging of all monitored events to the History.

The user can interact with the Flex locally by RS-232C or USB port or remotely by modem or Ethernet. The Flex will automatically generate an alert call to a variety of devices over serial, PSTN or TCP/IP networks. The Flex can also make a status call at user-programmed intervals of one to 255 hours. This allows all PageTek products in a system to report in automatically if desired to meet FCC monitoring requirements.

The Flex is powered by direct 12 VDC input or via a 115 VAC wall transformer, with optional internal battery backup.
