Advanced Smoke Group Limited – RTC Smokeclear Real Time Control Pressure Differential System

Description of Product

This is an assessment of the RTC Smokeclear

Real Time Control Pressure Differential System

manufactured by Advanced Smoke Group

Limited, incorporating the use of Door Position

Sensors (DPS) for close control of precise

closed door design pressures and open door

velocities, applicable to all pressure differential

systems.

The RTC Smokeclear Pressure Differential

System incorporates the use of a Door Position

Sensor (DPS) on each relevant door in the

system to communicate the location and

opening angle of each door in real time. This

information is communicated to the system

control panel. This information is used to

control fan speed to ensure the maintenance

of accurate compartment pressure or door

face velocity.

Key Factors Assessed

Mechanical Resistance & Stability

Safety in case of Fire

Safety in Use

Durability serviceability and identification

Issue Dated 30th October 2019

Certificate No: EW602

The scope of application for this product, in accordance with this Registered Detail, is considered to include all applications

where a pressure differential system designed, installed and commissioned in accordance with the current edition of BS EN

12101-6 Smoke and heat control systems - Part 6: Specification for pressure differential systems – Kits.

It is considered to be an acceptable solution, in accordance with the applicable volume of the current Approved Document B or

BS 9999 Approved Document B - Fire Safety, BS 9999:2008 Code of practice for fire safety in the design, management and use

of buildings and BS 9991:2011. Fire safety in the design, management and use of residential buildings. Code of practice and as

approved by the relevant Building Control body.

This Registered Detail only covers the applicability of Door Position Sensor technology as a part of Advanced Smoke Group

Limited’s

RTC Smokeclear – Real Time Control Pressure Differential System designed, installed and commissioned in accordance with

BS EN 12101-6 and does not cover the overall pressure differential system design nor the range of scenarios in which a

pressure differential smoke ventilation system is considered to be a suitable solution in order to achieve compliance with

the Building Regulations, but may be applied in such applications after full consideration of the design – see below.

The pressure differential system, of which the Door Position Sensors (DPS) form a part, shall be designed, installed and

commissioned in accordance with the current edition of BS EN 12101-6 Smoke and heat control systems - Part 6: Specification

for pressure differential systems - Kits

It is the responsibility of the Building Control body, in consultation with the Fire Authority, to determine if the use of a pressure

differential system is an acceptable solution as part of any particular application under the Building Regulations, either as part of

a code-compliant design in accordance with Approved Document B, BS 9999, BS 9991 or as part of a performance-based ‘fire

engineered’ solution utilising the approach outlined in BS 7974 Application of fire safety engineering principles to the design of

buildings. Code of practice

This Registered Detail is not intended to indicate the suitability of the RTC Smokeclear – Real Time Control Pressure Differential

System, incorporating Door Position Sensors (DPS) technology, for any particular application under the Building Regulations as

this will need to be determined on a project specific basis.

This Registered Detail confirms that the Advanced Smoke Group Limited’s RTC Smokeclear – Real Time Control Pressure

Differential System and Door Position Sensors (DPS) are suitable for use wherever a BS EN 12101-6 compliant pressure

differential system is considered to be applicable.

The provision of indicating equipment and override controls intended for Fire Service use shall in all cases be in accordance with

the standard specification referenced in ‘Supporting Documentation’ below, but for specific projects it may be considered

necessary to incorporate additional indication equipment and/or override controls, for example manual control points local to

protected lobbies, in addition to the central override control specified in paragraph 2.4 ‘Fire Service Control’ of the standard

specification. In all cases, the incorporation of additional controls must be agreed on a project specific basis with the Building

Control body, Fire Authority and any other Authorities Having Jurisdiction, as applicable.

The precise location(s) for remote monitoring of the system (noted in the “standard specification) and as required by any

relevant standards and specifications shall in all cases be agreed on a project specific basis with the Building Control body, Fire

Authority and any other Authorities Having Jurisdiction, as applicable.

All system cabling shall be in accordance with paragraph 5 ‘Cabling’ of the standard specification and with the current edition of

BS 8519 Selection and installation of fire-resistant power and control cable systems for life safety and fire-fighting applications –

Code of practice.

Suitable information shall be provided for the use of Fire Service personnel regarding the coverage and operation of the system,

including system indication and all override controls. It is recommended that the scope of this information be agreed with the

applicable Fire Authority. This information shall be encapsulated and placed in a suitable location, such as a premises information

box or within the Fire Control Centre where one is provided.

The Door Position Sensor (DPS) devices will be clearly marked to indicate that they should not be removed, as they part of an

active fire protection/life safety system (as “standard specification”)

On completion of the installation and commissioning of the pressure differential system, the Building Control body shall be

invited to attend acceptance testing of the system, including at minimum a demonstration of the following:

• That the system is activated by the appropriate fire alarm system input devices;

• That the pressure differentials and air velocities, or the extract volumes, are in accordance with the design specification, as

appropriate for the type of system, for the worst case protected space (e.g. the protected space furthest from the system fans)

and for any other areas, as requested by the Building Control body;

• That, where stand-by fans and drive mechanisms are provided in accordance with clause 11.7 of BS EN 12101-6, upon failure of

the duty fan, the stand-by fan(s) run automatically within a reasonable period of time;

• That, on failure of the primary power supply to the pressure differential system, changeover to the secondary/backup power

supply takes place automatically and the pressure differential system resumes operation within a period of not less than 30

seconds, or within a time period otherwise agreed between the Building Regulations applicant/the person carrying out the work

and the Building Control body, in consultation with the Fire Authority;

• That a simulated fault with the following system components are registered and displayed on the remote indication panel:

A. Door Proximity Sensors

B. Motorised Smoke Dampers

C. The duty fan(s) and, where applicable, the stand-by fan(s)

D. The primary power supply;

• That all system override controls operate as intended and are appropriately labelled as to their function;

• That all doors on means of escape routes can be opened using less than 100N pressure when the system is operating;

• That all components are provided with suitable and agreed signage, including marking to Door Proximity Sensors in

accordance with paragraph 3.5 of the standard specification.

On completion of the installation and commissioning of the pressure differential system, the Building Control body shall be

provided with a Completion/Commissioning Certificate issued by the system installer certifying that the system has been

designed, installed and commissioned in accordance with BS EN 12101-6 and the standard specification. This shall include

documentation indicating that the key system parameters (pressure differentials, air velocities or extract volumes, as appropriate)

have been measured as part of the commissioning process and the performance achieved is within acceptable tolerances of the

design specification.
