FIRE RESISTANT RANGE INS-240
Insulated Fire Resistant Steel Roller Shutter
GUARDIAN'S FIRE SHUTTER, the INS-240 Fire resisting roller shutter door is purposely designed for large openings, where insulation and fire resistance is a requirement.
Due to its unique and ground breaking construction, the radiant heat levels around the INS-240 roller shutter door drop from
65kw sq metre to an astonishing 2.7 kw sq metre,
WHAT DOES THAT ACTUALLY MEAN ?
This means that combustible materials can be stored half a metre away from a 1200oC inferno, increasing floor space and reducing risk and break down of fire compartmentation. Fire crews can safely tackle the blaze right next to the door, and anyone unfortunate enough to be trapped without an immediate exit can safely walk past the roller shutter, without fear of the radiant heat being as dangerous to them as the fire itself.
Exhaustive workshop and independent laboratory testing recently conducted on the INS-240, have provided conclusive scientific data to support these figures.
PRODUCT ACCREDITATIONS
The INS-240 shutters are constructed in accordance with clause 8 of BS476 part 22:1987.

Modes of activation
Fire Alarm Relay - Solenoid Release
On receipt of a 24 v signal from the fire alarm the solenoid releases the motor brake, which intern allows the shutter to close mechanically under controlled descent.
As a standard Guardian INS-240 fire shutters come with an auto resetting solenoid.
Fuseible Link Release
On activation the link, which is a soldered link, separates and releases at 68 degrees centigrade, in effect the temperature release of the link creates a signal to the relay which in turn powers the door down.
Again if there is no facility for a maintained supply the battery back up unit must be used.
Fire Door Interface (FDI)
In order to introduce safety into the system an FDI panel can be installed.
This includes an audio and visual warning.
Timed delay closing
Principally this unit is designed to delay the closing of the fire shutter; the fire alarm is linked to the audio visual unit.
On activation from the fire alarm the unit starts to “flash & sound”, this unit contains a programmable timer which effectively delays the signal to the solenoid release.
This unit is inclusive of a 24v DC battery backup system , which enables the unit to be linked into the fire alarm system by a set of volt free contacts.

Why have your door and shutter systems maintained?
- It is a legal requirement - as failure to show evidence of maintenance could mean prohibition & enforcement notices being served and fines up to £5000 and imprisonment for 2 years. 'Safety In Use', the New European CEN Standards legislation - States that all types of door should be maintained in an efficient state, in efficient working order and in good repair. For further clarification visit www.dhfonline.org.uk.
- Routine maintenance prolongs the operational life of the installation and ensures that the installation is kept in good working order.
- It ensures that the door is working in a safe and efficient condition - helping to prevent accidents and damage which in turn results in down time, effecting work flow, productivity and resulting in loss of revenue.
- It assists in identifying potential problems which can easily be rectified.
