Control Options
|
|
A
choice of three Control Modes are located outside of the ductwork for easy access and installation. The motorised Control Modes 5 and
6 can be fitted in 3 positions through 180° allowing maximum on-site
installation flexibility. All Smoke/Shield Control Modes must be in
the released position prior to connection.
Control Mode 1
Manual reset – with
volt free contact for provision of external indication of
damper status. Not available on
Vent/Shield.
Note: Vent/Shield PTC™ Dampers
and associated control modes are
reverse action with spring opening
(only available on Modes 5 and 6).
Mechanical Fusible Link Control
Mode 1 (Smoke/Shield only). Fail-safe by means of a unique and
patented mechanical fusible link
which operates at approx. 72 °C, complying with BS5588 Part 9:
1999. The link assembly incorporates a safety feature that ensures
the fail safe status of the damper if the link is not fitted on to
the ductwork. A manual test may be performed by simple unscrewing the
wing nut situated on the fusible link.
Control Modes 5 and 6
Optimised motor/spring return
control modes with remote resetrelease
facilities, with volt free
contacts for provision of external
indication, monitoring and control by
means of an Actionpac damper
control system, or by a suitable
alternative proprietary control format.
Electrical Thermal
Release (ETR) Control Modes 5 and 6. Fail-safe by means of a unique and
patented electrical thermal release
which operates at 72 °C or if power
supply is interrupted, complying with
BS 5588 Part 9: 1999.
The ETR incorporates triple safety
features, including an ingenious
device that ensures the fail-safe
status of the damper if the ETR is
not fitted on to the ductwork.
A manual test switch allows periodic
operation of the damper for testing
purposes simulating actual fail-safe
release under smoke/fire conditions.
For safety reasons the ETR is
designed to operate once only when
72 °C temperature is reached.

Specification for SMOKE / SHIELD PTC
Automatic smoke and fire dampers shall be of double skin spigot case having
continuously welded corners and spigot connections. Stainless steel aerofoil
blades of double skin construction, interlocking within twin trailing edges, the
interlocking providing a double metal seal. Incorporated within the blade
profile is a synthetic seal to ensure low closed blade smoke leakage at
ambient temperature. Accurate bearing, alignment, positive cap and bar drive,
and blade retention combine to provide a slimline double skin casing of high
rigidity, complying with DW 144 classes A, B and C.
Automatic smoke and fire dampers shall be tested to and comply with BS ISO
10294/1 classification ES, and European Standard EN1366-2.
Automatic smoke and fire dampers to be complete with factory fitted
installation frames (where specified) to the HVC 06/05/83 specification.
Automatic smoke and fire dampers shall be fitted with a snaplock interface
and the relevant control mode specified on the drawings. The snaplock
interface and control mode to provide closure with proportional torque control
and give visual indication of damper status. Dampers will be fail-safe by
means of electrical thermal release which operates at 72°C or by loss of
power, complying with BS5588 part 9.
Automatic smoke and fire dampers to be type Smoke/Shield PTC as
manufactured by Actionair, telephone 01227 276100.
