The EDAC 400-02 is a cost-effective, auto reporting dialler designed for industrial, domestic and small-business use. The EDAC 400-02 is an effective tool for alerting the user to events such as faults or changes in equipment state. It is physically compact, consumes little power and can be installed very quickly. Its ease of programming combined with simple installation make it highly attractive and cost effective in monitoring applications.

The EDAC 400-02 is activated by a contact closure, or opening, which results in the start of a user-defined dialling sequence, followed by the transmission of either an 8-second voice message or a 20-character pager/SMS message (subject to network availability). When an event triggers the auto-dialler, the EDAC 400-02 will make an alarm notification call. The EDAC 400-02 will pick up the phone line and call a list of people via telephone, cell phone or pager. The EDAC 400-02 speaks the pre-recorded message announcing the problem.

Upon receipt of an alarm call you may reset the EDAC 400-02 by simply pressing a numeric digit on your telephone keypad or by entering a user-defined PIN number. This will stop the unit making further alarm notification calls. Alternatively, the EDAC 400-02 may be interrogated by calling into it and listening to the voice message. This provides the opportunity to cancel/acknowledge the alarm inputs via the telephone keypad. This option would normally be used when the EDAC 400-02 is operating in conjunction with a pager and/or SMS messaging. Other options, such as Outputs, are user programmable either on site or remotely (via a telephone).

Once the EDAC 400-02 is in a cancelled state, the EDAC 400-02 will suspend its dialling sequence and remain cancelled until the event that triggered the alarm has been removed (cleared). If the EDAC 400-02 does not receive acknowledgment of an alarm, it will remain in dialling mode until the event that triggered the alarm is cleared, or the user-defined call count limit is reached.

All telephone numbers, messages, and functions are user programmable via a keypad and a single character display.

The EDAC 400-02 has numerous programmable features that enable it to be a flexible telemetry monitoring tool suitable for use in any situation. If you require information about the EDAC 400-02 and how it can be used with your monitoring application, please contact your supplier.

NOTE: Power supply should comply with Telecom PTC101 requirements if dialler is to be connected to Telecom NZ network and ACA requirements if dialler is to be connected in Australia. (Such as EDAC PB12)  Inputs Four, clean-contact, voltage-free trigger inputs such as relay contacts, a float switch or a micro switch are required. 

WARNING: Applying voltage to the Inputs of the EDAC 400-02 may damage the EDAC 400-02 and will void the product warranty. Outputs Up to four Outputs by jumper selection. Open collector type. Maximum current is 120mA per output. Each Output takes up one input channel.  

Telecom Line 

Two RJ11 sockets. A suitable cord can be provided compatible with the wall socket in your country. The inner two pins of the RJ11 socket are used for TIP + RING.  

RS232 Connector (DB9) Used for programming EDAC 400-02 configuration via Hyper Terminal and a PC. See section ‘Programming using RS232’ in ‘Application Notes’ for detailed instructions. Alternatively it can be plugged into a PLC/RTU or SCADA system, allowing the unit to provide a 2400 baud modem connection to an external device.  

Mechanical - Dimensions 192mm length x 110mm width x 35mm height. - Weight 250gm - Cabinet Aluminium base with screw on (M4 pozi-drive) aluminium lid. - Finish  powder coat. - Mounting 4 x 4mm mounting holes in the base of the cabinet. - Line in/Line out RJ11 standard (only the 2 inner pins are used as Tip + Ring).  

Messages 

- Site Message Four seconds of high-quality, user-recordable speech. 

- Acknowledged Four seconds of high-quality, user-recordable speech to identify when message inputs have been acknowledged. 

- Acknowledged Four seconds of high-quality, user-recordable speech to identify when message inputs have been acknowledged. 

- Idle Message Four seconds of high-quality, user-recordable speech to identify when the EDAC 400-02 inputs are in an idle state.  

Parameters 

- Maximum number of telephone numbers Four per Input or one list of 16 numbers 

- Maximum number of digits per number Twenty including pauses 

- Time duration of phone call (playtime) Variable 1 - 9 minutes -Wait time (between each call) Variable 0 - 9 minutes. 

- PABX access delay Two seconds for each user inserted pause - Recordable message time Up to eight seconds per Input 

- Dialling mode DTMF (tone dialling) Page 5 of 40  

Numeric Paging 

Twenty-digit numeric strings can be transmitted to a Numeric Pager to identify the site and active input trigger. Numeric paging can be configured via the EDAC 400-02 keypad.  

Alphanumeric Paging 

Multiple paging hosts can be used. A different host can be assigned to each Input trigger. - Paging host protocol TAP 

- Pager messages 20 characters per Input (i.e. 4 messages) 

- Max number of pagers 16 - Host password User programmable 

- Host ID User programmable (default PG1)  

Modem 

The EDAC 400-02 has an onboard 2400 baud V22bis modem (backward compatible with 1200 V22 connections) used for alphanumeric paging and remote configuration using Hyper Terminal. The EDAC 400-02 can also be put into transparent mode. This allows remote communications via a dial-up connection, to devices attached to the external RS232 connector such as a PLC or RTU.  

Programming 

Functions (including voice), are normally programmed using the keypad and single character display. The EDAC 400-02 can also be programmed through the inbuilt RS232 connector and Hyper Terminal; a Windows based application shipped with all versions of Windows. See section ‘Programming using RS232’ in ‘Application Notes’ for detailed instructions.   

Alarm Cancellation 

Alarm notification calls can be cancelled by using a DTMF touch-tone phone. The alarm can be cancelled by pressing any numeric key on your telephone keypad or by entering a PIN, depending on which option you have selected at the time of installation and programming.
