Fig. 1 shows in perspective the security chain in its secure position.
Fig. 2 shows in perspective the security chain disabled.
Refering to the drawings the security chain comprises, a security chain 6 and a secure self releasing anchorage housing 2 releasably secured to the housing by, for example solenoid, catch or similar (not shown)
In order for the end of the security chain 1 to be released as shown in Fig 2. The solenoid 4 is activated or de-activated.
To re-secure the security chain the feed to solenoid 4 Fig 2 is reversed.
Details of drawings 1. End of Security Chain 2. Secure anchorage housing 3. Door 4. Solenoid 5. Piston 6. Security Cahin 7. Gap between Door and Frame 8. Anchorage to Door
