Abstract

Abstract Security system for use with a plurality of swinging doors having individual key-released locks, comprising a plurality of deadbolts with a single electrically operable power means for each door controllable by control switch means located at a remote control point, safety switch means controlled by each door to prevent operation of the associated power means unless that door is closed and operable, after actuation of the control switch means, to cause automatic locking actuation of the associated plurality of deadbolts when the door is closed, and signal means for indicating at the control point closed and open positions of each door and active or inactive positions of the deadbolts.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 79 words
An institutional security system for use with a plurality of swinging doors, comprising control switch means located at a control point spaced from said doors, and a plurality of deadbolts electrically controlled by said switch means for preventing opening of each of said doors, said switch means being effective of moving deadbolts of a closed door to a locked position and of moving deadbolts of an open door to a locked position after said open door has been closed.
Claim 2
Dependent Claim 79 words
An institutional security system for use with a plurality of swinging doors, comprising control switch means located at a control point spaced from said doors, and a plurality of deadbolts electrically controlled by said switch means for preventing opening of each of said doors, said switch means being effective of moving deadbolts of a closed door to a locked position and of moving deadbolts of an open door to a locked position after said open door has been closed.
Claim 3
Dependent Claim 28 words
In a security system according to claim 1, a key-released lock mounted on each of said doors, and electrically operable power means for actuating said plurality of deadbolts.
Claim 4
Dependent Claim 35 words
In a security system according to claim 2, door position safety switch means controlled by each of said doors to prevent energization of the associated said power means unless said door associated therewith is closed.
Claim 5
Dependent Claim 48 words
A security system according to claim 3, wherein operation of a said safety switch means in response to closing of the associated said door will cause automatic locking actuation of said plurality of deadbolts cooperating therewith if said control switch means previously has been moved to closed position.
Claim 6
Dependent Claim 29 words
In a security system according to claim 3, signal means for indicating closed and open positions of said doors and active or inactive positions of said deadbolts associated therewith.
Claim 7
Dependent Claim 27 words
A security system according to claim 5, wherein each said power means includes an electric motor and said signal means includes position switches actuated by said motor.
Claim 8
Dependent Claim 38 words
A security system according to claim 5, wherein each said power means includes a vertically movable lock bar and actuating means for moving the same, and said signal means includes a switch actuated by each said lock bar.
Claim 9
Dependent Claim 14 words
A security system according to claim 7, wherein said actuating means comprises solenoid means.
Claim 10
Dependent Claim 37 words
A security system according to claim 8, wherein said actuating means comprises a pivotally mounted actuating lever interconnecting said solenoid means and said lock bar for lifting the latter in response to energization of said solenoid means.
Claim 11
Dependent Claim 66 words
In a security system according to claim 9, a deadbolt latch lever, spring means for moving said latch lever into active position to cooperate with said actuating lever to hold said lock bar in raised position, and an unlocking solenoid connected to said latch lever to move the same against the action of said spring means to inactive position to permit lowering of said lock bar.
