A security system (100) to prevent unwanted entrance through a hinged barrier (10) having a first side and a second side is provided. The security system (100) comprises a deadbolt lock operable from the first side of the barrier (10); a member (35) associated with the barrier (10) and adapted to extend from a first length to a. second length; an actuation mechanism (20) coupled to the member and adapted to extend the member from the first length to the second length and to contract the member from the second length to the first length, the actuation mechanism being associated with the deadbolt such that operation of the actuation mechanism from the first side of the barrier (10) actuates the member (35) and the deadbolt; a receptacle adjacent the barrier (10) for receiving a portion of the member when the member is extended by the actuation mechanism (20); and an override mechanism (40), operable from the second side separately from the actuation mechanism, configured to selectively prevent the member from being contracted and the barrier from being opened when the override mechanism is engaged, the system being such that when the member is actuated to the extended position and the override mechanism is actuated, the extended member and the receptacle provide security to prevent forced entry through the barrier (10). |
