SURVEILLANCE AND ALARM DEVICE FOR ROOM SPACES

Abstract: A surveillance and alarm device for room spaces, comprising an infrared radar (8) for controlling the lights as well as a fire and burglar alarm (8, 9, 10, 11). A basic alarm (2) is provided with a light controller (12) to be connected in series with a ceiling light fixture (1) in a room under surveillance, and is further provided with a microprocessor (9) or some other intelligent control circuit, adapted to control the alarm actions of said device either on the basis of a command issued by a lamp light switch (3) or a wireless remote controller (7) or on the basis of a command issued by a key switch (4). The light controller (12) included in the basic alarm (2) switches on said lighting fixture (1) as someone enters a room under surveillance or flashes said lighting fixture (1) in connection with an alarm.

Description: Surveillance and alarm device for room spaces. The present invention relates to a surveillance and alarm device for room spaces, comprising an infrared radar for controlling the lights as well as a fire alarm and a burglar alarm. An object of the invention is to provide a line of simple safety equipment for homes and offices that can be readily adopted and connected to existing electric and telephone equipment. This object is achieved according to the invention on the basis of the characterizing features set forth in the appended claim 1. One exemplary embodiment of the invention will now be described in more detail with reference made to the accompanying drawing, in which fig. 1 is a schematic view showing the wiring of a device of the invention to electric and telephone equipment and fig. 2 shows a block diagram for the components included in a basic alarm 2. The device comprises a basic alarm 2 to be connected in series with a ceiling light fixture 1 in the room to be placed under surveillance, said basic alarm including a fire detector 11 and a burglar-alarm infrared radar 8 and also a light controller 12 integrated in a single unit. The basic alarm 2 is provided with a microprocessor 9, which is adapted to control the actions of said device either on the basis of a command issued by a light switch 3 for lamp 1 or a remote controller 7 or on the basis of a command issued by a key switch 4. In its basic embodiment, the actions of alarm 2 are controlled by means of light switch 3. The control is effected by means of successive shorter or longer switch-on periods, issued by light switch 3 and set by a user. One or a plurality of basic alarms 2 can also be controlled by means of a basic shunt switch, which is a key switch 4. the key switch 4 is connected either to light switch 3 or to a supply line for an array of lights. The key switch 4 is used for cutting away one haIf-wave whenever the alarm is active. Thus, the basic alarm 2 produces an alarm both by sounding a siren 10 and by flashing the lights of lamp 1.Especially in the dark, such alarm is easily detectable from outside, even from a fair distance away. The basic alarm 2 includes also an automatically rechargeable backup voltage source 13 and, thus, the replacement of batteries is avoided. When a light controller 12 included in basic alarm 2 is in activated state, it switches on the light in a normal manner when somebody enters the room under surveillance. As an accessory, the device includes a robot alarm 5 to be connected with a telephone line by means of a tap socket 6 and including no keyboard for identifying the alarms by means of sequencing the siren sound of basic alarm 2. Hence, the robot alarm 5 does not require any input or output delays. The programming of robot 5 can be effected by means of a normal telephone and such robot can be connected as a separate unit without acutal installation or fixing of sensors. The robot alarm 5 includes a microprocessor for analyzing an alarm signal and calling the emergency numbers. Thus, this microprocessor is set in various operational states through the intermediary of a telephone. Furthermore, in addition to or instead of a light switch, it is also possible to employ a wireless remote controller 7 for the alarm control. The invention is by no means limited to the above exemplary embodiment but there are several alternatives for a skilled person to utilize the following and most important characteristics of the invention: connectable to a lighting fixture three devices in one: a fire and burglar alarm as well as automatic control for lights flashing of lights in alarm situation wireless transmission of alarm to a further alarm and/or additional alarms as a sequenced sound or a radio-frequency code connection of several alarms in series For example, said microprocessor 9 can be replaced with other intelligent circuit designs possessing a sufficient data processing capability for a sufficiently reliable analysis of the messages received from sensors 8 and 11 and for controlling said signalling devices 10 and 12 on the basis of such analysis.

Claims: Claims 1. A surveillance and alarm device for room spaces, comprising an infrared radar (8) for controlling the lights as well as a fire and burglar alarm (8, 9, 10, 11), c h a r a c t e r i z e d in that a basic alarm (2), provided with a light controller (12) to be connected in series with a ceiling light fixture (1) in a room to be placed under surveillance, is further provided with a microprocessor (9) or some other intelligent control circuit, adapted to control the alarm actions of said device either on the basis of a command issued by a lamp light switch (3) or a wireless remote controller (7) or on the basis of a command issued by a key switch (4), whereby said light controller (12) included in basic alarm (2) switches on said lighting fixture (1) as someone enters a room under surveillance or flashes said lighting fixture (1) in connection with an alarm. 2. A surveillance and alarm device as set forth in claim 1, c h a r a c t e r i z e d in that said key switch (4) is connected either to light switch (3) or to a supply line for a series of lighting fixtures. 3. A surveillance and alarm device as set forth in claim 1 or 2, c h a r a c t e r i z e d in that said device includes an accessory which is a robot alarm (5) to be connected with a telephone line and including no keyboard for identifying the alarms on the basis of the sequencing of the siren sound of basic alarm (2), said robot alarm being provided with a microprocessor for analyzing an alarm signal and for calling the emergency numbers.
