DE10305326A1 - Escape door test and control system e.g. for buildings, uses RF signal communicated to monitoring control point - Google Patents

Abstract

For assembly of the components it is assumed that existing standard door fixtures are adopted. In a condition of panic, the door is opened by conventionally actuating the door handle. Monitoring of the state of charge of the power source is permanently indicated, with a signal (RF signal) communicated to a monitoring control point, and communicated from there to a mobile RF phone/ public network telephone.

Description

The subject of our invention is the implementation of a control and alarm system for escape doors, doors to security areas, etc.

This system, consisting of control / transmission unit and receiver unit realizes optimal monitoring of escape doors, Doors closed Security areas, etc. while ensuring optimal security for tenants or owner of the building.

field of use

A door fitting with opening control and multiple alarm triggering, for surveillance of escape doors, Doors closed Security areas and the like

The state of the art consists of a swivel bearing screwed to the door below the handle Metal housing, which blocks the ratchet inclination in the rest position.

This fuse must also be activated screwed on the door become.

Such a secured door can be only after this mechanical blockage has been twisted out of the inclination range the handle, open.

There is a device in the housing which, when the housing is rotated out of the blocking area, the Circuit between a battery / accumulator and an acoustic alarm closes.

Turning back the case will mechanically locked. Unlocking and alarm cancellation at the same time is done by turning the key in the locking cylinder of the housing.

Especially in moments of panic by the human being that is compulsory in these situations Confusion, the spontaneous understanding of the interaction between left and blockage underneath prevented or at least delayed.

III. - The innovative potential the invention -

A) - under the assembly aspect -

The TKS fitting can be used with the existing ones Mounting options on a door with a commercially available Mortise lock (e.g. according to DIN). Under normal conditions there are none additional mechanical connections necessary.

B) - under the performance aspect -

In contrast to the state of the art an optical signal source (LED) becomes an acoustic signal on site activated, which in the idle position arming the DCS, by flashing slowly, in green Light indicates.

After opening the door, the opt lights up. source red, and the acoustic signal source emits a warning tone.

In addition, the in the housing integrated transmitter, coded for this condition, high-frequency alarm signal to the receiver, in the alarm control display Posted.

Lights up after receiving the signal the door on the display assigned light source (LED) red, and a warning tone sounds.

The cancellation of the alarm state happens through introduction and rotation of the system key in the lock cylinder of the door fitting.

The board (PL1) initiates the transmitter with the emission of the corresponding frequency.

At the receiving module is after receiving this signal the arming of the DCS again, by slow Flashing of the corresponding light source, in green light, with approx.0.5Hz indicates.

The extension of the TKS with a mech. or electronic unit that the door opening from the non-latch side (from the outside) from registered, is already planned in terms of construction.

This option does the additional monitoring a door equipped with the TKS, superfluous with a standard alarm system.

C) - under the service aspect -

Reaching the critical state of charge the energy source in the housing the fitting is flashed on site by approx. 2 Hz in green light displayed and in addition by a frequency coded to this state, to the receiver in Control display sent.

In addition to the acoustic and optical Status displays of the control display on site, according to this system option is activated, the forwarding of the message of the current DCS State initiated on the telecommunications level.

D) - under the flight aspect -

In contrast to the state of the art the handle of a door fitted with the TKS fitting can be so, be used without prior unlocking.

This property is especially important in Emergency of considerable importance as a possible escape without the through twisting the above mechanical pawl blockade Loss of time, guaranteed is.
