The automatic dialing alarm system shall be microprocessor based and have the capability to monitor 200 or 500 Modbus registers that are digitals (read/write coils) or analogs (holding or register) in any combination. In addition, the dialer shall monitor the 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 dialer shall begin dialing the first of up to 16 user-programmed telephone numbers.
The dialer shall support both Modbus Master and Modbus Slave modes allowing the SCADA/PLC system to be queried or the dialer be written to by the SCADA/PLC system.
The dialer shall speak user-recorded messages to the called party describing its location and the alarm conditions that are present. The dialer shall then verbally request that an acknowledgment be given. The called party shall acknowledge the call by momentarily depressing the '8', '9' or '*' key on their telephone keypad. If the dialer 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 dialer shall give a sign-off message, 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 dialer shall begin the alarm notification cycle again.
The dialer shall have relay outputs that shall remain energized as long as the dialer has any unacknowledged alarms or be programmed for other functions. This output shall be available to allow for wiring to an external horn, buzzer, light or other local alarm device. Alternatively, the user shall be able to program the dialer to allow remote activation of this relay from a telephone keypad.

All fuses shall be solid-state automatic resettable such that the user is never required to manually change a fuse.
|The automatic dialer shall be field upgradeable (without returning unit to the manufacturer) for the following:
- 14.4 Kbaud modem
|8 lists of 9 numbers, each number containing up to 40 digits
|5 seconds per input channel message
5 seconds for System Identification message
|200 or 500 Modbus RTU registers plus primary power, backup battery power, communications with Modbus devices
|Digitally recorded voice messages plus permanent library.
|5 second messages for, power loss, low battery message, user selectable via keypad or remotely for 1 alarm/normal messages for each input channel, 1 channel identification message per channel.
|The dialer shall be programmable from the integral keypad, remotely via a phone or locally or remotely via PC.
|Up to 144 available numbers up to 40 digits each.
Numbers can include '*', '#', delays, and detection of dial tone.
|The alarm dialer shall have the following alarm types:
- loss of primary power,
- low battery,
- Modbus communication loss,
- phone fault that can drive any relay
- Digital (read coil)
- on or off
- number of times in a condition - pulse totalization that can be multiplied by a scale factor and reported in engineering units
- accumulated time in a condition - total run time reported in Days Hours Minutes Seconds.
- Analog (read holding)
- a user-specified high or low limit for a specified period of time,
- a user-specified positive or negative rate of change.
All alarms shall be recorded with date/time in the event log.
|The automatic dialer shall have the capability to prioritize alarms by the telephone list designated to each alarm channel. Additionally, alarms shall be prioritized by time of day to different phone lists.
|The automatic dialer shall provide acknowledgement of alarms from:
- the front panel,
- a phone that is called with an alarm condition,
- a dial-in from a remote location with appropriate access codes.
All acknowledgements will be recorded in the event log with the date/time of the acknowledgement, the method of acknowledgement and the Caller ID if from a remote location.
|The automatic dialer shall have the capability of documenting all alarms, dial-out, dial-in, and alarm acknowledgement, activities with time and date to a standard parallel printer or over a modem connection to a PC.
The status report shall contain the last 1000 events. Each event shall have the date/time of the event and the action performed.
|The automatic dialer shall record the Caller ID in the event log of anyone calling into the dialer to acknowledge alarms or perform any programming functions.
|Each alarm channel shall be individually programmed to be either enabled for alarms, disabled or status only.
|The automatic dialer shall be capable of notifying of alarm conditions by the following methods:
- telephone and cell phone
- digital and alphanumeric pager
- modem call-out
- modem call-in
- relay activation (write coil)
Each alarm channel shall be programmable to continue alarm notification if the condition returns to normal.
|The dialer shall be capable of being armed or disarmed manually.
Arming or disarming shall be recorded to the event log.
|The dialer shall have internal battery back-up capacity sufficient for an 8-channel dialer to perform its alarm call-out function for a minimum of 48 consecutive hours upon loss of primary power.
|The automatic dialer manufacturer shall have a toll-free number for customer service calls. The automatic dialer shall have a 2-key sequence that can be entered from the local keypad that will place an automatic speaker phone call to the manufacturer's customer service facility.
|The automatic dialer shall meet:
- FCC Part 15, Class A and Part 68 requirements and shall have a valid FCC registration number per Part 68
- Industry Canada CS03 and have a valid IC registration number
