The door terminal can comprise a housing accommodating therein an access opening. The door terminal further comprises a stationary attached mounting plate to which the housing is detachably connected and designed to be essentially tamper-proof. Further development of the door terminal intends to make the installation simple and more universal, therefore the mounting plate presents a pivot bearing and a stopper, and the housing presents a cut free web and a lock operable from the front side. The door terminal can also have a pushbutton to release a locking device, and a protection pane covering the pushbutton.

Description

The invention relates to a door terminal with mounting plate according to the preamble of claim 1. The door terminal has a housing in which a profile cylinder with an associated electronic circuit board, an audible alarm and / or visual display means, an emergency button in conjunction with a switching block for Activation of a locking device, a protective button covering the emergency button and a stationary mounted mounting plate on which the housing is releasably secured and can be secured by a sabotage contact, is arranged.

Such door terminals are used as a compact device for emergency exits in the access-monitored environment. Such a door terminal is from the DE 196 52 348 A1 In a stationary mounted in the door area housing is a profile cylinder, which is used for alarm acknowledgment and free / arming the door. Furthermore, light-emitting diodes for the operating state "secured / unlocked" are integrated in the housing. The housing also houses an acoustic alarm and an emergency button together with a positive-opening switch block. The housing, which is mounted on a mounting base that is firmly anchored to the wall, is protected by a sabotage contact. The emergency button is provided with a non-splintering protective plastic cover against unintentional operation. In the event of danger, spacers of the protective hood break off by a strong blow, whereby the emergency button is depressed simultaneously. The door can then be opened almost without resistance, whereby an audible alarm is triggered

The terminal housing is pushed onto the mounting bracket mounted on the wall and fastened to the underside of the mounting base. Due to this mounting arrangement flush mounting, especially in existing system housing is difficult or impossible. because the necessary mounting space is not available. In principle, accessibility from the underside of the housing is not particularly advantageous with regard to the monastic attitude of the fitter. Furthermore, there is the problem that the mounted in the terminal housing electrical components are wired with on-site leads. Consequently, the detached terminal housing must be fixed during assembly work with one hand, so that further activities can be performed only with one hand. The existing sabotage contact is arranged on a separate bracket and is activated by the lower-side housing attachment. The disadvantage here is that the attachment of the housing can be solved with commercial tools. The peripheral edge of the mounting base requires an adaptation to the Gehauseform of the terminal, so that for different Gehäusevananten a corresponding number of different mounting base must be made.

The invention is therefore based on the object, a door terminal according to the preamble of claim 1 further so that a simplified and universal mounting is possible, with optional sabotage protection must be feasible The door terminal should be both for surface-mounted as well as for flush mounting suitable.

The object of the invention is achieved by the features of the characterizing part of claim 1. Hereby, a possibility is provided to mount the terminal housing exclusively by a front accessibility with little displacement can. The assembly is considerably simplified, in particular, a mounting in confined spaces is made possible. This assembly situation arises in particular in the integration of a door terminal in already existing installatron boxes or profiles or flush mounting

The space available for installation must extend beyond the outer dimensions of the door terminal housing only by the depth of the pivot bearing. The installation space moves due to the small dimensions of the pivot bearing in the range below one centimeter, so that the front-side appearance is not affected by excessively formed joints between the door terminal and the surrounding installation housing.

A sabotage contact is placed directly on the circuit board and activated when mounting the housing by the stop of the mounting plate. Separate brackets and supply lines for sabotage contact omitted. The extension of a door terminal with the optional sabotage contact only requires an exchange of the circuit board, since the mounting plate is basically designed by the stop for such expansion variant

The mounting plate is z. B attached to a wall. Preferably screwed, mounting holes in the mounting plate are slightly flared to ensure a secure support on the wall In principle, all mounting vanes the housing is initially moved toward the wall on the mounting plate, the stop and the pivot bearing serve as a positioning aid. Subsequently, the housing is moved into a preferably C-shaped bearing shell of the pivot bearing, wherein the free end of the bearing shell engages in a slot of the housing. Furthermore, it is possible to fold down the housing for connection work, wherein the pivot bearing and a slot cut through the slot cooperate. In the case of flush mounting the pivot bearing must, however, due to the depth of the Turterminals be designed in the form of a fold-out and / or extendable storage variant. Due to the positive engagement of the bearing shell in the slot in conjunction with the support of the housing to the stop an exact positioning of the housing is provided to the mounting plate. The exact positioning, in particular with respect to the stop of the mounting plate is required for a reliable operation of the lock and located on the circuit board optional sabotage contact, the z. B. is executable as a microswitch or reed contact. The tamper contact triggers an alarm in a control center or on the door terminal, so that appropriate action can be taken immediately by the front operable lock whose locking lug engages behind the stop when actuated, the housing is fixed dismantling on the mounting plate, as in conjunction with the in the housing engaging bearing shell neither a horizontal nor a vertical movement of the housing relative to the mounting plate is possible The connections between the housing and the mounting plate are made inaccessible from the outside, so that abusive and non-destructive disassembly is excluded After removal of the key housing is only to be opened by authorized personnel.

The housing can be solved by authorized personnel from the mounting plate to z. B. repair, maintenance or adaptation work to unlock the terminal, the lock is closed back by means of the key and the housing opened. wherein a web of the housing moves in the case of a surface mounting in the bearing shell, so that an articulated connection to the mounting plate is formed. The housing is held by the articulated connection form-fitting to the mounting plate and is supported with the bottom of the wall. The fitter can work both hands and in an advantageous mounting position. Work can be carried out conveniently from above, existing electrical connection to the on-site wiring are not subjected to mechanical stress.

The terminal housing encloses the mounting plate with the exception of the pivot bearing completely Thus, the mounting plate is not visible, so that only a universal mounting plate is used for Variationen the housing which does not have to be adapted to the shape and color of the housing As-closing means are all known Locksmith plug locks are particularly advantageous due to the simple and robust operating principle. In particular, the simple removal and installation when changing the locking groups facilitates such modifications.

All optical and acoustic display elements of the terminal can be integrated centrally in a module. This results in a total compact and therefore inexpensive unit that has been optimized in terms of the use of the existing space in the housing of the door terminal.
