Scout PLC 12/24

Specifications

The monitoring/alarm system shall be microprocessor based and have the capability to monitor 12 or 24 PLC registers via a Modbus serial connection. The system shall perform as a Modbus Master reading the user-specified registers in the PLC and assigning them to points. Each of these points shall be user-configured through the front panel as reading and writing coils and holding registers. The points shall be compared to limit conditions and if outside the conditions, but into an alarm. In addition, the monitoring/alarm system shall monitor the communication link, AC power and battery voltage continuously. Upon detecting an alarm on any of its inputs, a low battery condition or detecting loss of its AC power, the system shall begin dialing the first of up to 8 user-programmed telephone numbers.

The monitoring/alarm system shall speak user-recorded messages to the called party describing its location and the alarm conditions that are present. The monitoring/alarm system shall then verbally request that an acknowledgment be given. The called party shall acknowledge the call by momentarily depressing the '9' key on their telephone keypad.

If the system is not acknowledged during the call, it shall hang up, wait from 1 to 3600 seconds and then dial the next number in its phone list. If a successful acknowledgment occurs, the system shall give a sign-off message, allow access to program the system and hang up and then wait a user-programmed period of time for the alarm conditions to be corrected. If this period of time elapses and the alarm condition(s) still exist, the system shall begin the alarm notification cycle again.

The monitoring/alarm system shall support a relay output that shall remain energized as long as the system has any unacknowledged alarms. This output shall be available to allow for wiring to an external horn, buzzer, light or other local alarm device. Additionally, the user shall be able to remotely activate/deactivate the relay from a telephone keypad.
