MPS-4100 Transmitter

The Model MPS-4100 Transmitter consists of two major sub-assemblies, the 
antenna assembly and the Transmitter circuit board.

The antenna assembly is a planar or linear patch array (see Figure 1-3) coupled to 
a pulse modulated dielectric resonant oscillator located on the back of the 
antenna. The antenna directs the microwave energy toward the Receiver. The 
antenna assembly and associated DRO attaches to the Transmitter circuit board by 
means of stand-off fasteners so that the two form a single removable assembly.

The Transmitter circuit board includes the modulator circuit to drive the 
oscillator. One of six modulation frequencies can be selected via jumpers located 
on the board.

The Transmitter includes a Tamper switch with selectable NO/NC output that 
signals when the cover on the rear of the housing has been removed. The Tamper 
switch is a 2-position plunger (secure, alarm) and includes a pull-out position that 
disables tamper notification, for servicing the unit.

An optional method for Tamper detection (switched power) which requires no 
additional tamper wiring, has been incorporated in the Transmitter. With this 
option selected, the power to the Transmitter is interrupted whenever the 
enclosure cover is removed. This stops the transmission of microwave energy, 
resulting in an alarm condition at the Receiver.
