Model OMA-VM500A-6 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-VM500A-6-LV monitors
up to 8 switch closures (dry contacts) or 24 Vac/Vdc inputs.
This dialer allows the user to program a “normal” state and a
time delay for each input. A 5-second message can be recorded
to define each input. An additional local identification message can
be recorded to identify the dialer. When an input is different from the
programmed “normal” state for longer than the time delay, the unit
will dial up to 4 phone or pager numbers. The integrated voice
tells the user which zone is in alarm and the current status.
Call the unit at any time to hear a status report, including power
status. The user can complete all programming over the phone by
following simple voice instructions.
When the dialer 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 that
caused the emergency state. The unit ceases to be in the
emergency state once contact is made with the unit. When the dialer
is in alarm condition, it will dial all programmed phone numbers until
contact is made. If contact has not been made after dialing all phone
numbers, the dialer will wait 20 minutes and then begin calling
again. This sequence is repeated until contact is made. When the dialer
calls a voice phone number, it will play the local identification message
and the current state of any input that caused an alarm and power
status. The dialer will then prompt the user to enter the PIN. When the
correct PIN is entered, contact has been made and the dialer will stop
calling. If the dialer calls an answering machine or voice mail,
the dialer will leave the warning message and will continue to call.
When the dialer calls a pager number, it will transmit the
programmed local ID number, any inputs that have caused an
alarm, and the line voltage (power) status.Contact is made when the
user enters the 4-digit PIN number, or—if the user is on site—presses
the cancel button located on the front of the dialer.
If the input(s) return to the programmed “normal” states,
the unit will also cease to be in the emergency state.
