CHUBB COMPUTER PROTECTION CABINETS
To minimize heat conduction an outer casing of the thinnest steel consistent with strength is used. The whole unit is reinforced in vital places to enable the cabinet to withstand a severe impact of a fall when heated to high temperatures without damaging its fire resisting properties. The cabinet is insulated throughout with no less than 3″ (76 mm) of Chubb tested and certified fire resisting material which is solid, stable and does not deteriorate with age.
The overall body thickness is 4″ (102 mm) at the sides, top and bottom and is 3″ (76 mm) at the back.
The total thickness of the door is 4″ (102 mm) the minimum thickness of insulation over the boltwork which secures the door is never less than 3″ (76 mm).
The especially designed inner container is fitted inside the cabinet. Two point clenching together with a substantial rubber seal fitted to the back of the container door ensures that the ingress of moisture is eliminated. In addition the body joints are sealed against moisture and added protection is given by the automatic clenching on the container door.
This equipment is secured by 4-way boltwork. The boltwork is operated by means of a lever handle. The standard locking is one Chubb 6 lever keylock with stainless steel keys in duplicate.
As the size of the spool can vary considerably the internal arrangements of these cabinets are made to suit
individual client’s requirements.
The body of the cabinet is painted medium grey with the door painted light grey. The furniture is chromium plated and all controls are mounted on a stainless steel panel plate running across the width of the door. The inner cabinet has a mahogany frame, plastic covered modern , medium grey painted interior.
Chubb Computer Data Protection Equipment – Under Test
Chubb currently spend 2% of annual turnover on research and development.
At the Chubb factory in Wolverhampton, which has one of the largest testing furnaces in the world, the computer data protection cabinets are subjected to tests aimed at simulating actual fire conditions.
The test programme is exhaustive and continuous and widely regarded as the most demanding in the field.
A Chubb CP4 cabinet undergoing a typical furnace and drop test under the close examination of independent witnesses.
1. The CP4, loaded with magnetic media, after 2 hours’ exposure in the furnace, when the temperature has reached a maximum of 1010°C (1850°F).
2. The cabinet is dropped 9.144m (30 feet) onto a bed of broken rubble.
3. The cabinet is opened and the contents examined. Despite the shelves collapsing due to a deceleration of 100g the media was check-read and found to be unharmed.
This test is one of several test-specifications designed to expose equipment to the various hazards encountered in real fire conditions:- high temperatures, steam, humidity, dust, impact, explosion – all fatal to sensitive (and often vital) magnetic media. Chubb simulate many such tests in order to ensure their equipment will protect such media – if called upon. However, the only true test is survival under real-life fire conditions – proof by performance-and case studies are available showing the effectiveness of Chubb Fire Resisting Equipment throughout the world.
