Installation for protection against break-ins |
摘要 |
In the event of an alarm being raised (e.g. by a sensor 34) by an attempt at breaking into a protected space (36) such as a safe or a strong room, a rapidly hardening foam is suddenly projected around or into the space to be protected. The expanding foam can also be used to drive additional door-barring means into position. The foam may be made by mixing two components that react together. The components can then be stored in tanks (23, 24), where they occupy little volume until the alarm is raised. The components are mixed in a mixing head (27) and projected into the space through a nozzle (28).
