HIGH SECURITY PIRAMID “HS” VERSION GENERAL: The MEA (Electronic Assemblies) for the “HS” Version sensors are derived from our Models SDI-76XL and SDI-77XL. The microwave transceiver and main circuitry of the “HS” Series sensors are virtually identical in features and performance characteristics to the standard PIRAMID XL(2) Series dual technology sensors. However, the “HS” Version of the PIRAMID XL is classified as High Security, as it offers high security features such as “Anti-Masking” and “Remote Self-Test”. In addition, the “HS” version offers enhanced detection capability when compared to the standard PIRAMID XL and XL2 versions. The detection parameters are altered to enable the sensors to offer greater overall detection capability for slow moving, fast moving and crawling intruders. Technical Description: The current anti-masking circuitry is integrated into the tamper circuit and utilizes an FPGA (Field Programmable Gate Array) for convenience. The anti-masking and MW supervision is connected in series with the tamper output using a separate relay located on the Main Printed Circuit Board ("N" Revision). Microwave Anti-Masking - Detection of a MW anti-masking attempt varies depending on the material used to mask the sensor, but generally microwave anti-masking detection is effective within 4 inches (10 cm) of the sensor faceplate. The detection circuitry locks a relay into an alarm condition once the anti-masking is detected. The relay will reset approximately 12 seconds after any anti-masking violation is removed. When the anti-masking is activated, the tamper contact on the terminal strip will show an open circuit. Passive Infrared Anti-Masking - The passive infrared anti-masking utilizes an “active” IR sensor for anti-masking. An active infrared transmitter is located on the IR Printed Circuit Board and transmits through the IR Fresnel lens to a receiver located in the IR Lens Snout that protrudes from the top of the IR Lens Module. If the IR Lens is covered or masked, the receiver cannot receive the transmitted signal which causes the IR sensor portion to initiate a tamper alarm. The relay will reset immediately after any IR anti-masking violation is removed. The IR anti-masking is effective within approximately 5 cm of the IR lens. Housing Tamper – This tamper switch is mounted at the back of the main printed circuit board. It provides a normally closed output to terminals 8 and 9 on the main printed circuit board. The output of terminal 8 and 9 will OPEN if the electronic assembly is removed from the housing. Note: There is no reset time associated with the tamper switch. Note: There are no settings associated with the anti-masking alarm feature. It is activated at all times.

ADJUSTMENTS THE SENSITIVITY CONTROL SWITCH The Sensitivity Control Switch controls the amount of motion required within the surveillance area to create a sensor alarm. The Sensitivity Control switch adjusts the distance, in inches, that a target must move toward or away from the sensor to activate the microwave sensor portion. Note: The most critical adjustment for stability is the Sensitivity Control Switch as it is often necessary to adjust the Range Control Switch near maximum in order to attain the maximum specified range of the sensor. The Sensitivity Control Switch adjusts the exact (minimum) distance an object must move toward or away from the sensor to initiate a microwave sensor alarm. A field setting of 1, 2, 3, 4, 5 and 6 offer tremendous stability but reduced “transverse” detection. A field setting of 7, 8, 9 and 0 (0 = Maximum sensitivity) offer excellent transverse detection but reduced stability. Please refer to Figure 7 shown below for the actual movement in inches required by PIRAMID XL-MIL for microwave sensor detection to occur.

THE RANGE CONTROL SWITCH The Range Control Switch controls the range of the sensor as it automatically adjusts the range of both the microwave and passive infrared sensor portions. It is good practice to adjust the sensor’s range to the lowest setting possible to attain the desired security. However, the sensor is designed to provide stable performance even with the Range Control switch adjusted near the maximum ranges (8, 9, and 0 settings - Note: 0 = Maximum Range).

Caution: The distances noted are very conservative estimates of the actual range. You must verify the actual range by carefully walk testing the sensor. Note: “Rule of Thumb” - always adjust range and sensitivity to the lowest possible setting to attain desired coverage. This will enable the greatest stability performance!
PASSIVE INFRARED RANGE ADJUSTMENT There is a passive infrared sensor range adjustment. The small passive infrared sensor printed circuit board is equipped with a three position (HI, MED, LOW) IR Range Adjustment Switch. The greatest range for the infrared sensor is obtained by having the passive infrared RANGE ADJUSTMENT switch in the HI position. However, it is prudent to perform a careful walk-test as the desired coverage may be attained in the more stable MED or LOW positions. PROTECH recommends the lowest possible setting to provide the desired range.
PIRAMID HS Features The H.S. Models of PIRAMID offer several “special” high security features that were incorporated into the standard PIRAMID units to provide sensors that satisfy virtually all high security requirements specified by U.S. Government security regulatory agencies. The special features are listed as follows: HS Features 1) Anti-Masking – Special circuitry detects an obstruction of the sensor’s faceplate and causes the alarm relay to change state and register a continuous alarm condition.

2) Remote Self-Test – Enables the Stereo Doppler Microwave sensor and passive infrared sensor to be tested from a remote location in the same manner as if physically walktested. 3) Remote RF Power Shut-off – Enables the microwave radiation to be shut-off from a remote location. 4) Mechanical Tamper Housing – Normally closed tamper switch with terminal connection. 5) Conduit Equipped Wiring Entry – The wiring entry at the back of the unit is a ½” liquid tight conduit fitting that provides environmental and tamper-proof protection for the wiring.

MW SHUT-OFF PIRAMID “HS” VERSION – WIRING INSTRUCTIONS Note: 1. Power in is 8.5 to 20 VDC @ Approximately 200 mA. 2. Tamper switch is a normally closed circuit. 3. The voltage input for the MW/IR “Self-Test” is 5-15 VDC @ 30 mA maximum. The “SelfTest” circuit tests both MW and IR sensors simultaneously by causing the relay to change state. 4. MW shut-off voltage input is 10-14 VDC @ 12 mA maximum. 5. Terminal No. 2 on the main Printed Circuit Board is the ground return for all of above voltages. 5
Specifications
Control Voltage Input (SELF-TEST) ----------------------- 3 to 15 VDC (1000 ohms) Control Voltage Input (RF SHUT-OFF)-------------------- 9 to 18 VDC (500 ohms) 1. 2.
If RF SHUT-OFF is to be utilized with the same power supply that is powering the sensor, leave jumper J1 intact and route DC voltage (pos.) to SHUT-OFF terminal. If RF SHUT-OFF or remote SELF-TEST is to be utilized with a different power source than the one powering the sensor, cut Jumper J1 and route DC voltage (both pos. and neg.) to SHUT-OFF and COMMON TERMINALS. (Note: This procedure is for ground-loop prevention).
IMPORTANT: KEEP IN MIND THAT DURING THE 1 -MINUTE STABILIZATION TIME WHEN THE SENSOR IS FIRST POWERED UP THAT THAT THE SENSOR FACEPLATE MUST NOT BE BLOCKED BY YOUR BODY OR ANY OTHER OBJECT. BLOCKING THE SENSOR FACEPLATE MAY CAUSE THE ANTI-MASKING CIRCUITRY OF THE MW PORTION TO ACTIVATE. NOTE: UPON MICROWAVE ANTI-MASKING ACTIVATION THERE IS AN APPROXIMATE 12 SECOND TAMPER OUTPUT RESET TIME STARTING AFTER THE MICROWAVE ANTI-MASKING VIOLATION HAS BEEN REMOVED.
