Description

Outdoor surveillance and lighting center

Passive infrared detectors are usually used to monitor the outside area of an object (building). These detectors switch on one or more assigned lamps after detecting movement.

This leads to frequent, unnecessary and unwanted switching on of the outdoor lighting by animals or the residents of the building or guests.

The invention achieves:

1. that the surroundings (garden) of the property or the facade (windows) or parts thereof can be monitored selectively and without gaps.

2. that incorrect switching is avoided, since each sensor channel is assigned a time module, and thus the response delay and arming time of the channel can be adapted to the circumstances.

3. that different terminal devices can be switched individually or in groups, depending on which sensor(s) have been activated.

In addition, an input is provided for triggering a panic switch, which means that all end devices can be switched on by a command, e.g. via remote control.

A contact from an existing alarm system can also trigger this function.

A. Functional description of timer input 1-n:

A potential-free contact is provided as the input signal. (See Appendix A)

The following functions can be triggered:

1. direct switching of the signal

2, start a delay time (adjustable);

After the delay time has elapsed, the input is armed for an adjustable period of time.

This means that an input signal that occurs during the delay time will not be passed on.

An input signal that enters while the channel is armed will be forwarded.

After the arming time has elapsed, the channel returns to the standby state.

B Functional description coupling level

In the coupling level, the input signals influenced by the time blocks 1-n can be optionally linked to the power outputs 1-n.

An input signal can be switched to several outputs.

It is also possible to switch several input signals to one output or to distribute them to several outputs.

This allows both individual devices and groups of devices to be switched.

In addition, the following switching inputs are provided:

Panic button

Contact from any existing alarm system.

£ Functional description power output

The power modules 1-n have the task of switching end devices with higher power

H. Ertl Rotenburg, 27.01.95 Leipziger Strasse 31 27356 Rotenburg / W, gschutzansprüche 1. Outdoor area monitoring and lighting center for central recording and evaluation of alarm sensors and for switching end devices with various functions. characterized, that a time module is used which enables a sensor channel to be armed with a time delay and the duration of the armed state to be set, and which can switch on one or more power outputs for an alarm time. that a coupling level is available in which sensor channels and power outputs can be optionally linked to one another and which has additional inputs for e.g. panic buttons and alarm systems ; 2. Outdoor area monitoring and lighting control center according to protection claim 1, (attachment drawing input time module) Input time block: characterized in that the switching pulse of a sensor is given to IC2 and thereby an adjustable arming time is started, at the same time an adjustable dead time is started in IC3. The output signal from IC2 (arming time) is switched to AND-GATE IC4C, the output signal of IC3 (dead time) is negated and applied to IC4C, the switching pulse of the sensor is also applied to AND-GATE IC4C so that the output of IC4C only becomes logical 1 when: the time window of the arming time is pending, the dead time window has expired, and another switching pulse comes from the sensor. The output of IC4C starts the adjustable alarm time (IC5). The alarm time on signal is switched to the power outputs via the coupling level. 3. Outdoor area monitoring and lighting control center according to protection claim 1 { Annex drawing input time module Bus + output board) coupling level; characterized in that the ON signal of the alarm time can be switched to one or more power outputs simultaneously via the coupling diodes D1-D6 and switch Sl, segments 1-6. In parallel, a logical ON signal (+12 V) can be applied via the diodes D7-D12 via a potential-free contact (K7.1), thereby switching on all 6 power channels.
