Colt Shaft

Description
The Colt Shaft comprises:

- Duty and standby extract fans rated at 300°C for 2 hours
- Colt Seefire duct termination
- Colt Seefire stairwell ventilator
- Ducting to link builders work shaft (by others) to fans and duct termination
- (select) Motorised smoke damper and grille to each lobby (or) Doorman door actuator for each lobby (for a FD30 rated fire door provided by others)
- MCC/Fan starter panel linked to main control panel
- Pressure sensor to each lobby
- (Optional) Smoke detector to accommodation close to each lobby.

Builders work requirements
The builders work shaft is to be substantially straight, vertical and directly adjacent to the lobbies. The construction is to have a smooth internal face and minimum air leakage. The internal cross section is to be no less than 0.6m² and the aspect ratio no greater than 2:1. Where a fire door is used for connection to the lobby, the shaft is to be wide enough to accept a door of at least 655mm wide and deep enough to allow the door to open 30°. Where a fire door is used an open mesh grille is required in the shaft at each storey to prevent risk of falls down the shaft.

The fire door between the lobby and the accommodation will be fitted with smoke seals (FD30S rating).

Unless otherwise specified the ducting will be constructed from galvanised steel to DW144.

Please note that it is possible that the ducting is in a location that requires fire rated ducting.
