Ademco - 760, 760-6, 760-12 Ultrasonic Motion Detectors

Nos 760,760 6,760 12 r equally its own plug in and contains a rechargeable standby power can provide at the No 760 No 760 6 and INFORMATION Nos 760.769 6 and 760 l 2 Ultrasonic Motion Detectors emit invisible and inaudible sound waves which detect the of a moving object such as an intruder Each unit contains a receiver transducer and a transmitter may be independently aimed to achieve coverage straight ahead of the unit or up to 90 to either side The units may mounted against a wall or ceiling or in a comer without any need for brackets No 760 must be powered The Nos 760 6 and 760 12 require power from a 6V DC and 12V DC source respectively 4 hrs of standby power Except as noted herein these instructions 760 12 of the detectors can provide indoor protection for an area up to approximately 30 feet long and 14 feet wide Additional can be used in larger areas without interfering with each other note cautions in TYPICAL LAYOUTS and 2 pattern of sound waves emitted by these units is set up by reflecting off of walls ceiling floor furniture and other stationary in the area Any movement of objects or persons in the area causes some waves to be reflected at a changed fre known as the Doppler effect When the frequency of the received waves changes the shift is detected by the elec circuitry in the unit and an alarm signal is initiated via a relay wired into the protective circuit of the alarm system detector transmitters and receivers will operate at all times regardless of whether the control to which it is is ARMED or DISARMED Whenever and while motion is detected the units LED will light and its relay con will transfer Alternatively when the detector is connected to a control that can provide a suitable switched voltage to indicate the control ARMED or DISARMED state the detector can be programmed relay and transmitter operation See OPTIONAL OPERATING MODES herein Nos 760 6 and 760 12 have additional provision for use of an external LED which can duplicate remotely the indication the detector built in LED optional ultrasonic test meter is available such as the No 453 for connection to up to two detectors levels in the protected area s and can be used with a chart recorder for a permanent record of disturbance conditions Complete instructions accompany the ultrasonic test meter Only late production versions of the No 463 two YELLOW jumpers on their PC board are suitable for use with No 760 series detectors PRECAUTIONS the area to be protected carefully before installing any units Even though the detector contains circuitry to minimize effects there are conditions as described below which may appear as motion to the detector and result in unwanted When determining a location for the unit take care to avoid the following provide optional modes of indicates distur and CURRENTS such as created by space heaters air conditioning vents rising heat from radiators or baseboard heat and strong drafts such as those resulting from loose fitting doors and show windows or walls that shake when traffic passes the unit on a sturdy inside wall wherever possible SOUNDS from telephone be ls or radiator valves located directly in the area to be protected OBJECTS such as house pets or other animals on the premises as well as hanging objects that tend to sway or doors that can be moved by air currents best location for the unit is 4 to 7 feet from the floor safely away from drafts CONSIDERATIONS pattern of the ultrasonic waves set up by each pair of transducers in the detector is oblong and at maximum sensitivity a nominal range of up to 30 feet and a width of approximately 14 feet as shown in Diagram la Actual coverage how is affected by these factors AND AIMING Each unit receiver can be aimed in the same direction as fts transmitter or in a different Various coverage patterns can be obtained See Diagrams la and 1 b Coverage up to 90 to either side may obtained REFLECTION and easily reflect uttrasonic waves Glass tile floors mirrors walls and most solid surface areas are considered surfaces areas that have highly reflective surfaces coverage is greater because the surfaces are containing soft sound absorbing material tend to reduce the range of the unit Examples of this kind of surface carpeted floors draperies heavy plush furniture etc AND TEMPERATURE Ultrasonic waves are affected by atmospheric humidity and temperature Between the and worst combinations of conditions range Can change noticeably In general low humidity and high temperature the best longest range and high humidity and low temperature give the worst shortest range The actual range is a function of both these conditions straight ahead TYPICAL COVERAGE PATTERNS unit different dire ions and receiver aimed each other TO 30 I 1 b PATTERN VARIATIONS LAYOUTS keeping in mind the aforementioned coniiderations and other factors mentioned below the installation may be laid out number of detectors may be placed in the same area without interfering with each other as long as the following basic rules are observed Do not direct units at each other unless the distance between them exceeds 60 feet Diagrams 2c and 2e illustrate this Units may be placed on opposite walls or the same wall provided their centers are offset at least 12 feet from each if aimed straight ahead Diagrams 2a and 2f illustrate this Back to back installation may be considered See Diagram 2b Placement in adjacent wmers as shown in Diagram 2d is effective Don place units too close together as some range shortening can occur Note minimum spacings indicated in Dia 2 necessarily direction unit faces and shape determined by aiming of transducen 2 Typical Layouts AND WIRING detector is designed for mounting flat against the wall or in a comer Mounting brackets are not necessary Diagrams 4a 4b show the locations of the mounting holes unit should normally be mounted with its long dimension vertical to permit its transducer heads to be aimed to the side straight ahead as required If desired however almost any mounting position may be used including ceiling mounting Connections wiring well with break away wall for surface wiring is provided adjacent to the units terminals See Diagrams 3a 3b 4a 4b Connections should be made in this order T ninals Nb NC To connect a closed circuit protective system use terminals NO and C Note A tamper may be installed in the unit by using a TP 6 Tamper Pack instructions accompany it Remote Terminals GND and SIG are provided for optional connection to an ultrasonic test meter such as No If used see instructions with the meter The No 453 is powered cannot be powered from the detector power source For the No 760 6 or No 760 12 the GND wnnection must be taken from the negative DC power input the AC line via its individual transformer see Diagram 3b 760 6 or 760 12 Only Optional External LED Connect as shown in Diagram 3b Also cut the YELLOW on the PC board see Diagram 4b Note The LED positive lead may be run directly from the DC if the run is shorter than from the detector Control Post and Options See OPTIONAL OPERATING MODES If one of the options is to be selected run the between the detector s and the main control and cut the necessary jumpers CAUTION the Day Shut Off options is selected do not cut jumpers until completing steps 5 and 6 and the AND TESTING and
