Tuya OTD-40T 4 Tech Outdoor Detector
INTRODUCTION
OTD-40T is a special four-tech (PIR+PIR+MW+ASIC) complex detector for outdoor intrusion. The signals of 3 sensors are with super stable and dependability by its advanced multi-grades digital signal processing technology. And they can offer 3 different detection modes on 2 sensitive grades in order to choose the best detection way for spot environment and gets the best rate between the best detection ability and the minimum false alarm rate. With normal “AND” and “OR” modes, OTD-40T detector is also with “EI” mode to avoid the damage of dopes spraying on the lens. Its unique water-proof design is totally fit for outdoor installation. At the same time, OTD-40T is also with other functions such as anti-masking automatic setting and alarm type memory etc.

INSTALLATION GUIDE
Select the best installation point fit for PIR and MW technologies. Put OTD-
40T onto the selected place and keep it away from door, window, running
machine or heat sources. If one detection place needs two or more sensors,
please to refer to MWSY-8 control board for installation (see MW sync-
hronization section to avoid MW interference.
WALL FASTENING
In order to get the best signal covering scale, detector should be installed on 2.1m height and vertical adjustment to position A. Anyhow, detector can be installed to maximum 4 m height. Make sure that there are no counterwork in front of the detector and it is with a wide view. Remove the front cover, release the screws and then pull out the PCB. Break the pre-set hole, (Figure 4) , if necessary, disclose the “wall inlay pre-set hole” and tear open once “wiring hole” ; mark the point of the hole on wall and put the “wall inlay” label on the pre-set hole. Drill 3 6mm holes and screw in the “wall inlay screws” , let its front extremity be 5/6 mm from the wall. Cross the wire from the cable hole and fasten the bottom cover onto the wall, confirm its front extremity enter the obligate site.
TESTING
- DIP 1 switch on “OFF” (anti masking cover “OFF” )
- DIP 5 switch on “OFF” (LED actives)
Note:
During this mode, anti-masking is limited.
MW
Tune the microwave tuner to a minimum, (capacity can be adjusted from 2-15m) ; to the extremity of protection area; when LED indicator turns off, operation radial movement to the detector, check MW detection by green LED. If green LED doesn’t light, turn the MW tuner in clockwise to increase its capacity; repeat this test for several times till you get the required distance. Remarks: MW adjustment: turn the capacity to the minimum, for MW can penetrate wall while over high capacity is not helpful for detector function in its protection area. (MW gets highest sensitivity when it performs radial movement to detectors)
PIR
Close the front cover, when LED indicator turns off, perform the horizontal movement in the detection area, check the detection status of PIR through the yellow LED. This step can check whether there is deal corner in the detection area; when PIR gets highest sensitivity when horizontal movement to the detector. When all DIP switches are in “OFF” status, monitor is in standard operation. Anti-mask cover control /AND / high sensitivity /LED activation If want to get max. monitoring, please refer to “monitoring mode” section.
Note: When there is interference to the monitor, the anti-masking cover
function will be limited.
MONITORING MODE
AND
DIP 2 switch on “OFF” status If three sensors (2*PIR&MW) get the detection signal at the same time, alarm will be trigger. This mode is fit for installation with unstable factors.
OR
DIP 2 switch in “ON” position Any of the sensors gets detection signal, alarm will be triggered. This mode is fit for high stable environment and requires the detector with very high detection ability.
EL (MODE)
DIP 3 switch is in “ON” position During the status, DIP 2 switch is useless. If three sensors get the detection signal at the same time, (such as AND mode) , or if it they gets more MW signal while there i torth italian which needit as are provided. detection mode, but it may exist PIR shadow area, or somebody spray the dope onto the PIR lens willfully to damage the PIR detection.
SENS L
The DIP 4 switch is in the “ON” position Detection sensitivity of both sensors are reduced.
- PIR: During the time, signals detected by both negative and positive period of PIR are limited.
- MW: the detection response speed of MW is 0.5 seconds, running speed is 0.6m/second.
FUNCTION
Anti-masking function
Anti object block the MW may cause alarm by the twinkle of LED indicator, and the signal is transported to monitoring center by MASK connector. Alarm status will last till the causes of formation are cleared away.
Activation of anti-masking function
DIP 1 switch is in “ON” position The activation of anti-masking function is the final operation. After activation, OTD-40T enters self-check status; during the time, LED indicator will twinkle for 100 seconds. During the time, close the front cover and keep away from the detector, detector will enter automatic setting status and perform automatic addition- ustment of anti- masking height. The most important point is, during the time, there isn’t anything approaching the detector to avoid its automatic setting. LED OFF
DIP 5 switch
In “ON” position, it will limit detection display. When connecting INHIBIT cable or pulling out the equipment, detector will start its display for 30 seconds after the first detection.
MW OFF
- DIP 1 switch is in “OFF” position
- DIP 5 switch is in “ON” position
Note:
During this mode, anti-masking is limited. When LED indicator is in “OFF” mode, anti-masking function is limited. INHIBIT is connected, monitoring center is broken, LED indicator doesn’t activate, MW turns off to avoid radiation to the protection area.
Relay control
When INHIBIT is connected, monitoring center is broken, alarm relay is under limitation mode.
Memory
When INHIBIT is connected, equipment is disconnected and the first alarm will be displayed. (see figure 14). When equipm ent is re-connected, memory will be set again.
MW synchronization
Connect the INHIBIT cable of OTD-40T to MWSY-8 control board, each sensor will be synchronized, in this way, wrong detection caused by MW interference can be avoided. It is fit for the environment that needs 2 or more OTD-40T
WIRE UP THE TERMINAL
- The contact is closed normally, if the front small cover or the whole detector from the wall, contact will open. (sensor connects with wall in- lay style monitor)
- DC:9-16V / 30mA
- The alarm output is close normal and its contact will open during alarm.
- INHIBIT: recognition input for plug in/draw out. +12 tands for recognition of equipment drawing out.
- Anti-masking cover output, contact is closed when it is normal.
VERTICAL ADJUST
NOTES AND WARNINGS
Even the most sophisticated detcetors can sometimes be defeated or may fail to warn due to :DC power failure/improper connection, malicious masking of the lens,tampering with the optical system, decreased sensitivity in ambient temperatures near that of the human body and unexpected failure of a component part. The above list includes the most common reasons for failure and recommended that the detector and the entire alarm system be checked weekly, to ensure proper performance. An alarm system should not be regarded as a substitute for insurance. Home & property owners or renters shouldbe prudent enough to continue insuring their lives & property, even though they are protected by an alarm system. This device has been tested and found to comply with the limits for a Class B digital device, pursuant harmful interference in residential installations.

However, there is no guarantee that interference will not occur in a particular installation If this device does cause such interference, which can be verfied by turning the device off and on, the user is encouraged to eliminate the interference by one or more of the follow measures:
- Increase the distance between the device and the receiver.
- Connect the device to an outlet on a circuit different from the one that supplies power to the receiver.
- Consult the dealer or an experienced radio/TV technician.
