Request to exit (RX)
The RX feature is used to signal the use of an opening. This device is equipped with one internal SPDT switch
which monitors the push pad. The device can be connected to a security console, or may be used as a
single door alarm when used with a horn and power supply. The RX switch option should not be used to
control a load, but as a signalling switch (2 amps resisitive maximum).
