Model DA2DAC is a wired non-battery, DC powered door contact sensor and receiver set, used for doors
or entries that are always closed, with the added feature, of sending a wireless signal “only once while
the door is opened and not again, until the door is secured and reopened. The wireless signal is sent to
a Model DARD (receiver sounder, included), over 100 feet away.

Mr Chime offers the “Model DA2D”, Battery operated unit, if power is not available at the entry
