Roku Compact Interface

PIR_Z

PIR-Z and PIR-Z-MR (MR=Moisture Resistant for outdoor use)

'Passive Infrared Motion Detector' Suitable for HD410, HD810 & HD1010

Features:

Small footprint (2.5 x1.7 inches)
The PIR_Z_BOX (assembly) is 2.6 x 2.6 inches
LED for trip indication
Sensitivity adjustment available outside the enclosure
Pulse Delay adjustment available outside the enclosure
3.3 volt operation (direct connection to the various HMS interface boards)

'PIR-Z-MR' Version has moisture resistant clear coat applied to all surfaces of both the main board and the Z-DOTS PIR daughter board. The 'adjustment' openings and the LED opening should be protected from direct rain either with tape or mounted down. Although the box is not a moisture resistant design, it will self purge any moisture trapped inside and the clear coat will protect the board.. The Z-Dots board was coated with the 'Prism' in place to help protect the Infrared detector from moisture. No guarantee against failure due to the elements. The box is shipped with a moisture resistant compound applied to the phone jack connector. The box should be protected from direct rain!

The RJ/11 connections are as follows (requires 6 conductor telephone cable)

Note: It is recommended that both wires be tied together as specified below)

0V = Red and Green (GPIO-0V)

3.3V = Black and Yellow (GPIO-3V)

MD (Motion Detect goes low with detection) = Blue and White (GPIO-BTNx)

Description:

The 'Z-dots' PIR board is utilized and is mounted to the right end of the 'mother board' as show in the picture above.

This 'Z-dots' board has sensitivity range from about 10ft to 5ft. Counter-clockwise (from the box access) is maximum sensitivity or about 10 feet. Clockwise the sensitivity is about 4 or 5 feet

The Pulse Delay adjust the duration of the 'move detection' pulse. Counter clockwise (from the box access) is minimum pulse duration (about 2 seconds). Clockwise is maximum pulse duration of about 12 minutes. This feature is not linear. Very little clockwise movement of the pot sets several to many seconds of detection pulse duration.

Note: The typical connection to any most HMS interface boards is a 3 pin Molex connector (order the HMS-6PH-MX-xx Cable). Pin 1 is ground (0 volts), pin 2 is MD (Motion Detect) and pin 3 is 3.3V. Manual connections can be made to any HMS Interface board that has 3.3V interface. For connections to terminal block order the DB15-TB10-3V terminal block adapter and the HMS-6PH-TB-xx Cable (xx is the number of feet).

Note: The PIR 'averages' the scene over time. It may take a couple of minutes for 'storing' the scene in memory after power up.

Note: Does not work through glass.
