Model OMA-VM606 monitors up to eight switch closures (dry contacts) which allows you to connect a wide variety of sensors such as magnetic door or window switches, thermostats, fluid level switches and motion sensors. The OMA-VM606 allows you to program a “normal” state and a time delay for each dry contact input. A five-second message can be recorded to define each input. An additional local identification message can be recorded to identify the OMA-VM606 dialer. When an input is different from the programmed “normal” state for longer than the time delay, or the power is out for longer than five minutes (default is 5 minutes however this is user selectable) the unit will dial up to eight phone or pager numbers. If contact has not been made after dialing all phone numbers, the OMA-VM606 will wait 20 minutes and begin calling again. This sequence is repeated until contact is made. The integrated voice tells you which input is in alarm and the current status. You can call the unit at any time to hear a status report including power status. All programming is accomplished over the phone following simple voice instructions. When the OMA-VM606 goes into an emergency state it will energize the alarm relay, activate the alarm buzzer and begin making emergency calls. When the unit dials a voice number it will first play the local identification message and the current status of any inputs which caused the emergency state. The unit ceases to be in the emergency state once contact is made with the unit. Contact is made by the user entering a personal identification number (PIN) after receiving a call from the unit, by entering the PIN number when calling in to the unit or by pressing the pushbutton located on the top of the dialer. If the input(s) return to the programmed “normal” states, the unit will also cease to be in the emergency state. If the OMA-VM606 calls an answering machine or voice mail, the warning message will be left and the unit will continue to call. When the OMA-VM606 calls a pager number, it will transmit the local identification number, any inputs which have caused an alarm and the power status.
