Wayfinder® Fire Resisting Partition
A range of wide span, laterally operating rolling shutters designed to prevent the spread of fire or maintain security between floors in areas representing a fire risk such as shopping centres, hotels and large commercial properties. The shutters can accommodate curves that harmonize with building structures and allows large spaces to be protected whilst minimizing requirements for special preparatory work. They are also designed to protect large areas of floor space without imposing restrictions on building design.
The shutter is mounted solely on its top track, along its entire length: floor tracks are not required. Structural supports are minimal and eliminate the need for unsightly vertical members.

A cold rolled track section with mild steel side plates to form a fire resisting section 150mm deep. 75 x 50 x 5mm angle brackets are provided at approximately 600mm centres for fixing to a suitable structural member. Tracks can be manufactured to suit infinite designs including curves and site applications. Fire resistant material above the track is available on request.
 

Finish
The shutter curtain is supplied bright spangled galvanised. All other components are protected by rust inhibiting primer paint. Additional finishes, including polyester powder coating, are available on request.

Electrical
Standard voltage: 415V, 3 phase, 50 Hz. The electrical equipment can be rated to suit the power supply available. The supply should be provided by others and terminated in a switched isolator box next to the coil box housing. The motor position can be handed to suit the site conditions. A control panel is provided which is usually installed outside the coil box housing which typically will include the following features as standard:
Open, close and stop buttons.
Key switch test facility.
Connection facility to the building fire alarm system, typically requiring a normally open/normal closed volt free dry contact connection.
An audible warning of the shutter closing.

Audible warning of the opening and closing of the shutter.
Variable time delay prior to closing.

Options
Battery standby. Battery backup or alternative powered systems to the standard range are available. Where a battery operated system is provided, the battery system should normally be housed within the control panel enclosure. The power output should give a minimum of 3 open/close operations. Full details are available from Northern Doors design office on request.
