Automatic Purging Unit: F-BO-AFE70-2FAAST™ Fire Alarm Aspiration Sensing Technology
OverviewThe FAAST Automatic Purging Unit provides a fully integrated
and compact solution with user-selectable preventative or event
triggered purging programs. An intelligent and installation-
friendly design ensures AFE70-2 is a cost effective and reliable
means of preventing pipe network contaminant blockages.
DescriptionASD systems continuously monitor the air in a
protected environment, potentially subjecting
the system to contamination over time. In order
to prevent the build up of pipe or aspiration hole
contaminates, regular ASD system purging with
compressed air is essential.
In contrast to conventional purging
systems,Honeywell’s compact and user-friendly
AFE70-2 unit features a single built- in Solenoid
valve, which initiates the release of air into the
ASD system. This valve also increases reliability
by protecting the unit from any compressed air
damage and can be accessed through a control
board that is integrated into the housing.
Installation time is greatly reduced, thanks to a
compact and fully integrated design, removing
the need for mechanical and electrical control
devices. Further cost savings can be leveraged
by a reduced need for cabling and pipe work to
commission the system.
With user-definable purging processes and
customisable program features, AFE70-2
delivers continuous and uninterrupted air flow
and is also optimised to assist with benchmark
preventative maintenance regimes, through
automatic purging processes that can be set
up at specific times. These purging processes
are independent of any fault-initiated purging
procedures performed by the system.
Designed with the engineer in mind, the system
offers excellent flexibility; external devices -
such as a push- button or a central timer – can
be connected to an input to allow initiation of
additional manual or automatic activations of
the purging process.

Cold storage & freezer application monitoring
Aspirating Smoke Detection (ASD) technology is ideal for installation in cold environments where traditional point or beam detection is unsuitable, due to high levels of moisture and ice particles in the atmosphere. FAAST LTTM combines the most advanced ASD technology and flexible pipe network design to deliver the earliest, most accurate smoke detection with false alarm immunity. Typical cold storage and freezer applications include:
• Pharmaceutical & medical stores
• Food/drink produce stores
• Leasire centres e.g. ice rinks
There are a number of factors that make many traditional fire detection systems unsuitable for cold environments:
• Temperatures from -45°C to +8°C / -49°F to 46°F
• Heavy condensation
• Water vapour clouds
• High airflows diluting smoke
• Poor smoke transport due to low thermal conductivity
• Inaccessibility for installation, maintenance, testing and
replacement
Fire risks in these applications are considerable and include:
• Electrical or mechanical faults in conveyors and transport
equipment
• Electrical equipment and wiring (in the environment or
housed in the roof space)
• Lighting systems
• Hot spots resulting from maintenance operations
• Discarded cigarette butts
• Arson
Typical areas where an ASD fire detection system provides an effective alternative to traditional detection methods include:
• Food processing plants
• Retail food distribution
• Ambient stores (pharmaceutical)

FAAST Fire Alarm Aspiration Sensing Technology®
Sampling pipe network
Achieving optimum performance, accuracy and reliability depends upon correct installation of both the device and the sampling pipe network. It is essential to ensure the unit is protected from any contamination and the following recommendations should be considered in order to leverage the full performance capability of the system.
Pipe installation considerations
PipeIQTM three-in-one design, configuration and monitoring software is provided as standard with FAAST LTTM. During the planning stage, PipeIQTM
will provide an isometric design of the pipework system and may not take into consideration the following factors that may impact final correct design:
• Environment• Feeder pipe run• Offsets• Obstructions
Environmental considerations
Environmental conditions can affect installation, operation and maintenance of the system, so please consider the following factors when designing the sampling pipe network:
• Temperature: from ambientto operational temperature; large fluctuationsoccur when doors are open/closed duringloading/unloading
• Humidity: High levels of humidity fog areprevalent during loading/unloading activities
• External influence: Internal trafficmovement, lorries, forklifts, conveyors,mechanical shovels and accumulative dirtbuild-up
Pipework application
Installation of the sampling pipe network
Most installations will use ABS Red or White sampling pipe work; this is approved and tested for FAAST LTTM. Optimum system design requires as much straight pipe work as possible. However, in reality bends and offsets will be required to create most application designs.
It is recommended to use the preferred fittings (shown in Figure 1 a-f below), designed for use with FAAST LTTM. Please note: 90° elbow bends (Figure 1a), should not be used.
Accessories image descriptions:
a. DO NOT USE a 90° elbow bendb. Standard pipe clipc. Girder clip for fitting standard pipe clip*d. Sweep bende. 45° elbow bendf. Flexible connector
* Please note: fixings and hangers are availablefrom a variety of manufacturers.

In all cases, the correct pipe clip should be used to accommodate for pipe slippage in the event of expansion and contraction from temperature fluctuations. Most pipes are affected by temperature fluctuations; the amount of expansion is generally 0.1mm / m for every 10°C / 50°F increase above installation temperature.
Using the appropriate clips allows expansion and contraction to occur naturally. However, positioning the pipe up against a wall or obstruction such as a girder (see Figure 2 below), can prevent expansion/contraction.
Expansion clip Flexible connector
Support clips need to be spaced as detailed in the table below.
Pipe Size Bracket spacing in metres
25mm 20°C / 68°F1m
30°C / 86°F0.95m
40°C / 104°F0.85m
50°C / 122°F0.75m
60°C / 140°F0.70m
70°C / 158°F0.60m
In cold environments where high water/humidity are expected, additional ASD pipe network protection is required.
A water trap can be fitted to the pipe network to ensure that water droplets do not enter the ASD unit; moisture simply falls into the trap and can be flushed out of the system during routine maintenance checks (see Figure 3 below).
Preventing water and high humidity detection issues
Figure 2.

Gradient of pipe system aprox. 1-1.5%
Please note: No offsets around obstructions in pipework, clear line of site to water trap
Figure 3.
Temperature impact on pipes
5
FAAST Fire Alarm Aspiration Sensing Technology®
Added system protection can be achieved by offsetting the sampling points. This prevents sample point
blockages from large water droplets and also prevents airflow faults from occurring.
Installing pipework on a slight gradient towards the ASD detection unit also encourages any moisture build-up
in the pipe network to flow towards the water trap. Please note: the offset must be towards the water trap.
FAAST LTTM is ideal for cold stores and freezer room monitoring, because the unit can be mounted outside of the protected area. To ensure correct system operation and performance, please consider the following guidance:
Cold stores and freezer monitoring considerations
Air return
It is important that the air sampled from the protected area is returned to prevent condensation build-up in and around the exhaust of the unit and to alleviate any flow monitoring issues that could arise from pressure differentials between the protected area and the unit position (see Figure 5 below).
Figure 5.
Pipe with hole in the bottom: risk of condensation blocking the aspiration hole and humidity is sucked in.
Pipe with hole at an angle: 30º angle allows condensation to drop down.
Aprox. 30º angle
Figure 4.
For additional protection, the aspiration hole can be situated at a 30º angle (see Figure 4 below); this prevents
water ingress into the pipe network, preventing the need for subsequent flushing during routine maintenance.
6
Electronics protection
Protection of the ASD unit electronics is essential in the coldest environments. This can be achieved by installing a length of pipe between the FAAST LTTM device and the inlet to the protected area.
The pipe length allows cold air taken from the protected area to warm up, preventing damage to the FAAST LT unit (see Figure 6 below). The following pipe length specification is recommended:
• Down to -20°C / -4°F environment: 5 m pipe length minimum• Below -20°C / -4°F environment: 15 m pipe length minimum
Please note: This guidance is based on a normal ambient temperature (~22°C / 71°F), outside of the protected cold area.
Figure 6.
Pipe lagging and insulation
Where build-up of condensation is an issue, lagging the inlet pipe from the protected area to the ASD unit should always be considered to avoid condensation or frosting of the pipe network. In extreme conditions,
extensive insulation / lagging of the pipe network is recommended (see Figure 5 below).
Figure 7.

FAAST Fire Alarm Aspiration Sensing Technology®
Manual blow through
A manual blow through system is recommended in a cold store, and should be used with a closed end-cap, removing the pressure relief valve
(see Figure 8 to the right). External in-line filter
Safety valve: close before blowing the compressed air into the pipeline
Compressed air inlet: e.g. snap-on fitting
Sampling points
It’s important to ensure sampling points are not sit-uated near entrance doors to the cold store, freezer or the blast chillers.
These locations are the most likely for high condensation and ice crystal formation on the
sampling points (see Figure 9 to the left).

Overview
The Honeywell Refrigerated Storage Sampling Kit provides
a standardised method of smoke sampling for Refrigerated
Storage facilities in a considerably improved manner
allowing simplified installation with reduced maintenance,
thus promoting more reliable and hassle-free operation.
The Honeywell Refrigerated Storage Sampling Kit has
been designed to replace standard cone-shaped sampling
nozzles installed at the ceiling in existing or new Refrigerated
Storage facilities. This kit can be installed in the entire facility
or combined with standard sampling points if required. The
aim here is to reduce direct ice blockage of the sampling
points hence this kit is recommended for installation in
areas where higher humidity is likely to occur as a result of
vehicle and pedestrian traffic (e.g. areas close to doorways or
perimeter of the facility).
This kit is treated as a standard sampling hole in the
Honeywell ASD system design, in terms of system
parameters (e.g. sampling hole location, hole size, transport
time, sampling hole sensitivity)
Description
The sampling kit consists of outer and inner parts with
the sampling pipe penetrating the Refrigerated Storage
sandwich panel. The sampling pipe through the sandwich
panel and inner parts are made of ABS plastic which is
suitable for low temperatures down to -40 °C (-40 °F). The kit
comprises a restriction assembly, placed above the sandwich
Refrigerated Storage SamplingVSP-860

• Eliminates the need for expensive HDPE (high density polyethylen
pipe inside the Refrigerated Storage facility
• Eliminates the need for costly access equipment hire for on-going
service/maintenance
• Eliminates the need for heat tracing
• Less prone to blockage due to icing
• Provides a generally more robust ASD installation for these unique
environments
• Provides considerably improved aesthetics
• Minimises the need for “Back Flush” systems
• Offers all round cost savings
