covered with a gauge cover shell to protect it from shock. The quadrant is luminous, with a full scale of 360 bar, a resolution of 5
bar and a reserve indicator under 50 bars. A second PSI scale is provided.
2.5. Automatic demand valve with audible warning device (pos. E in fig. 1,2,3 and fig. 5)
The demand valve consists of a reinforced plastic housing and contains both t both the device that delivers the air and the acoustic
warning device. The button (pos. 1, fig. 5) allows the air supply to be stopped and is deactivated upon the first inhalation. The
regulator can be of type A or BN depending on the mask version (see section 2.6). It is connected to the pressure reducer via a
medium-pressure hose with a swivel fitting.

Note: The operation of the SCBA, if equipped with connector EN 148-3, it is still possible with other masks conform to the same standard
exclusively in emergencies and in case it is not available (due to accidents) the correct mask.
• Type "BN" with positive pressure and DIN 58600 bayonet connector, to be used with Type BN demand valve. BN masks are also
provided with a special patented mechanism that enables use with negative pressure devices such as SCBA demand valves or
canisters having a standard thread connector to EN 148-1. (Rd 40x1/7").
Available models:
- TR 2002 BN CL3 (code 113010000), TR 2002 S BN CL3 (code 113070000) certified according to EN 136:98 class 3

EN 137:2006)
• Type "B" with positive pressure and DIN 58600 bayonet connector, to be used with Type BN demand valve. Available models:
- TR 82 B (code 112310000) certified according to EN 136:98 class CL3.
- TR 82 B CL3+ (code 11231FR00) certified EN 136:98 class CL3+ (flame engulfment test passed, as required by EN 137:2006).
- TR 82 B E CL3+ (code 112120000) certified according to EN 136:98 class CL3+ (flame engulfment test passed, as required by EN
137:2006), equipped with special hooks designed to be connected to firefighting helmets.
The TR 82 series masks are one size fits all, the TR 2002 Class 3 and 3+ series masks are available in two sizes (S/M and M/L) or
one size fits all. See the attached instructions of each mask for more information on their features and appropriate use. The mask
codes are shown in the table in par.11.
2.7. Accessories
2.7.1 Four-ways valve
The Automatic 4-way connection or 4-way valves is an accessory provided upon request that allows you to:
- feed a second operator who will be equipped with an individual warning device signal on their demand valve;
- connect the self-contained breathing apparatus to an alternative source of air to prolong its autonomy and/or to ensure a safe
escape whenever the main feeding source has suffered an accidental interruption. When fed by an alternative source (at 5.5
bar), the cylinder is automatically excluded.
The detailed instructions for use of the 4-way valve are attached to the accessory (instruction code 960040000).
2.7.2 Additional warning device
The additional warning device can be installed, upon request, on the RN series devices and allows you to have a continuous alarm
signal, in addition to the intermittent alarm signal already provided with the demand valve.
It is installed on the reducer and simultaneously activates itself with the main warning device.
2.7.3 Second outlet hose
The second outlet hose is an accessory mountable on request on all SCBA RN series and allows to connect a second demand valve
to the device for an additional user or a rescue hood. NB: when you use the second outlet hose to connect in a second operator,
accurately calculate the autonomy of the device, which will be halved.
2.7.4 Rescue hood
The escape hood for second operator is an accessory that can be used in conjunction with any SPASCIANI SCBAs.
To use the rescue hood, remove the second operator cap on the pressure reducer and mount the medium pressure tube supplied
in the set (see point 2.7.3). Detailed instructions for assembling and using the rescue hood are enclosed with the accessory itself
(instruction code 960250000). The bag is made of highly flame-resistant material and can therefore also be used in Type 2
breathing apparatus.
2.7.5 Excess flow valve
The cylinder valve can be optionally equipped with an excess flow valve, mounted in place of the dip tube. This valve enhances
the already high safety level of the valve/cylinder assembly by limiting the release of air to a very high flow rate in the event of a
failure (e.g., accidental disconnection between the valve and a charged cylinder).
2.7.6 ATEX self-contained breathing apparatus
On request, the self-contained breathing apparatus can be supplied in the "Atex" version, with specific marking for use in explosive
environments. See section 8 for details on this line of equipment.
2.7.7. Containers
Two types of wall-mounted containers are available, made of plastic and metal, which allow the self-contained breathing apparatus
to be stored in a ready-to-use condition. The plastic container is designed for wall mounting with four anchoring points and features
