Apparatus and methods for entryway access control using serial discretely coded radio frequency transmissions initiated by a single user access request signal. The control apparatus is battery operated and includes a user actuatable input selectively generating a single electrical initiation signal. Circuitry provides first and second conditioned output signals responsive to receipt of the single electrical initiation signal, the output signals enabling first and second transmission channels, respectively, of an RF transmitter or transmitters. A signal delaying circuit delays output of the second conditioned output signal relative to output of the first conditioned output signal.

Access control using serial discretely coded RF transmissions initiated

Presence detecting apparatus and housing and mounts therefore are disclosed, the apparatus including control circuitry, an emitter array, detector array, and background compensation sensor mounted and housed to provide a safe and effective detection area characterized by substantially constant detection sensitivity over the defined detection area while avoiding undesired detection of objects present outside the detection area. The emitter array and detector array are mounted and housed so that the detector array is substantially isolated from transmission in the housing of selected electromagnetic signals from the emitter array.
