• Break away the Cable Knockout wire entrance. • Open two holes for surface or corner mounting (See Figure A). • Mark the location for the mounting screws. - Use the enclosure as a template. - Pre-start the mounting screws. • Route wiring as necessary. Route to the rear of the base and through the wire entrance. Make sure all wiring is unpowered before routing. • Securely attach the base to the mounting surface. • Return the circuit board to the base. • Install the mirror. 4.0 Wiring Apply power ONLY after all connections have been made and inspected. Do NOT coil excess wiring inside the detector. • Terminals (-) & (+): Power limits are 6 to 15 VDC. Use no smaller than #22 AWG (0.8 mm) wire pair between the detector and the power + NC C source. • Terminals C & NC: Alarm relay (reed) contacts. Do not use with capacitive or inductive loads. Alarm Cover • Tamper contacts: "T" Models only. Off Connect to a 24-hour Protection Circuit Plug the wire entrance hole with the foam plug provided after all wiring connections have been made. 6.0 LED Operation The detector uses a tricolor LED to indicate the various alarm and supervision trouble conditions that may exist. See the following chart: LED Steady red Steady yellow Steady green Flashing red Flashing red (4 pulse sequence) Cause Unit alarm Microwave activation (walk test) PIR activation (walk test) Warmup period after power-up Microwave or PIR failure Replace Unit If the detector experiences a Microwave or PIR self-test failure, it is in need of replacement. During walk testing, the LED will light for the first technology (microwave or PIR) and then light red to indicate a detector alarm. The LED will not indicate activation of the second technology by lighting its color. 7.0 Feature Selection LED ON/OFF JUMPER PLACEMENTS • LED On/Off Pins: Placing the Program Plug in the jumper across the LED selection ON Position LED pins allows operation of the Edge of Pins tricolor LED. If the tricolor LED Circuit Board indication is not desired after setup and walk tests are LED completed, move the jumper from Program Plug across the LED selection pins. in the OFF Position Moving the jumper to the OFF position does not prevent the Edge of Circuit Board LED Pins tricolor LED from indicating a supervision trouble condition. LED 8.0 Setup and Walk Tests • Select the vertical starting angle from the chart. Broad Coverage Mirror Mounting DS825 DS840 Height 25 (7.5) 40 (12) 6.5 (2.0) -6° -4° Required Settings for Pet Applications 7.5 (2.3) -10° -8° 8.5 (2.6) -12° -8° Height and desired Range listed in feet (meters) • The angle adjust markings are on the mirror. Slide the mirror forward or back until the angle hash marks are in-line with the markers on each side of the frame. NOTE: See Section 11.0 for Pet Applications. • Place the LED Jumper in the ON position. • Wait at least two minutes, after applying power, to start walk tests. NOTE: During the warm-up period, the tricolor LED will flash red until the unit has stabilized (approximately one to two minutes) and has seen no movement for two seconds. When the LED stops flashing, the detector is ready to be tested. With no motion in the protection area, the LED should be OFF. If the LED is on, recheck the protection area for disturbances affecting the microwave MW Adjustment (yellow) or PIR (green) technologies. Establishing PIR Pattern Coverage • Turn the Microwave range adjust to minimum and replace the cover. Minimum • Walk test across the pattern at its farthest edge, then several times closer to the detector. Start walking from outside of the intended protection area, and observe the tricolor LED. The edge of the pattern is determined by the first green, PIR activation of the LED (or the first red activation if the yellow microwave LED activates first). • Walk test from the opposite direction to determine both boundaries. NOTE: The center of the pattern should be pointed toward the center of the intended protection area. • While standing 10 to 20 ft. (3 to 6 m) from the detector, slowly bring your arm up and into the pattern to mark the lower boundary on PIR alarm. Repeat from above for the upper boundary. NOTE: The center of the pattern should not be tilted upward. If the desired coverage cannot be achieved, try angling the coverage pattern up or down to assure the pattern is not aimed too high or low. Establishing Microwave Coverage Wait one minute after removing/replacing the cover so the microwave portion of the detector can settle. Wait at least ten seconds between the following walk testing procedures. • The tricolor LED should be OFF before walk testing. • Walk test across the pattern at the intended coverage's farthest end. Start walking from outside the intended protection area and observe the tricolor LED. The edge of the microwave pattern is determined by the first yellow, microwave activation of the LED (or the first red activation if the green PIR LED activates first). • If adequate range can not be reached, increase the Microwave Range Adjust slightly. Continue walk testing (waiting one minute after removing/replacing the cover) and adjusting the range until the farthest edge of desired coverage has been accurately placed.
