VIMO C1SPR001 Network presence sensor card

The C1SPR001 network presence sensor board has been designed to allow the control of the presence of a Vca or Vcc voltage source and to activate an alarm signal to a telephone dialer if the controlled source ceases for a duly programmed time. For this purpose, its input must be connected to the secondary of the transformer for 24Vac operating voltages for controls (thermostats - etc.) < about 35Vca. The control timing is pre-available using jumpers for delays in the implementation of the alarm signal.
