Main features

A RELAY with remote control by mobile phone

Two output terminals (X or Y) can be used as:
  • An SMS-controlled switch. SMS texts for switching particular terminals on/off are configurable (e.g. "light on", "light off" and "sunblind close", "sunblind open"). Any such instruction can be automatically echoed by David sending you an SMS report.
  • A time-switch which can be activated remotely via a mobile phone. (the switch-on period is configurable from 1 second to 10 hours).
  • A relay with dialling-in remote control. Up to 50 tel. numbers can be authorized for each relay. Because calls are not answered dialling-in control within GSM is free of charge. (David only checks the caller’s number and – if the number is authorized – responds with relay activation.) This can be used for parking access control, door lock control, switching lights etc.
Each authorized number can have a limit to the number of calls. For example, when the customer is only allowed to open the parking lot entrance for 30 times at most, any further access is denied to him/her. The customer can then be re-authorized for entrance control via SMS by the administrator.

Reporting to mobile phone

Four input terminals (A to D) can have their switching on/off reported by SMS (e.g. "freezer mains dropout" or "freezer mains recovered")
  • SMS reports can contain up to 30 characters.
  • Each input can have up to 8 tel. numbers programmed for where reports are sent to.
  • SMS reports can be emphasized by subsequent calls.
  • David’s current status (input/output terminal states) can be interrogated remotely via SMS instructions.
  • David can perform periodical calls every 24 hours allowing you to monitor its functioning.
  • If you use a prepaid SIM card, David can send you a warning SMS whenever a critically low credit balance is detected on periodic interrogation.

  Accessories
The GD-04A back-up module is a back-up battery imbedded in a specially-enlarged cover. The module provides David with the ability to work approx. 12 to 24 hours continually without an external power supply. The battery is auto-charged during normal operation.
The GD-04P link cable allows you to link David to a PC through a USB port and perform any desired configuration using GDLink software (supplied on a CD with the package). This fully-fledged configuration tool is especially suitable for those who perform frequent installations.
The GD-04D DTMF module allows relay X and Y control by entering numeric codes (DTMF codes) on the telephone keypad during calls. (First call David’s tel. number and wait until the beep response, then enter the DTMF code and finally terminate the call.) The module can be installed by plugging it in to the appropriate digital bus.
The GD-04R radio module provides David with wireless connectivity to devices of the Jablotron OASiS system. By plugging the module into the digital bus connector your David is able to report the following:
  • Panic alarm triggered by a panic (RC-80, 87, 88 or 89)
  • Movements in the protected area (detected by JA-80P or 85P detectors)
  • Fire alarms or threats (detected by a JA-80S)
  • Breaking glass (detected by a JA-85B)
  • Window / door opening (detected by JA-80M or JA-82M detectors)
  • Gas leaks (detected by a JA-80G)
  • Exceeding the maximum/minimum allowable temperature limits (detected by TP-82 or TP-83 thermostats). In addition, the current room temperature can be acquired via SMS. Up to four different locations can be monitored – each A to D input can have a single thermostat assigned. This feature is suitable e.g. for anti-freeze protection in a conservatory or for fire protection in a server room.
  • Any contact switching on/off (detected by a JA-80M)
