1. Scorpion Product Presentation

2. Why test? Protect Lives and Property
Ensure system performs as expected: will the alarm activate if there is a fire?
Validate Insurance
Will your insurance still be valid in the event of an incident?
Statutory Regulations
Require functional smoke tests to ensure the detector goes into alarm (BS 5839)
The detector shall be tested in in situ (NFPA )
100% of all installed system components must be tested (DIN 14675: )
Supported by local and international standards such as 5839, VDS, etc.

3. Regulations
“Point smoke detectors should be functionally tested by a method that confirms that smoke can enter the detector chamber and produce a fire alarm signal (e.g. by use of apparatus that generates smoke or suitable aerosols around the detector). It should be ensured that the material used does not cause damage to, or affect the subsequent performance of the detector…”. BS Part 1:2002 Clause 45.4 d:
“… the entire system should be inspected and tested to ensure that it operates satisfactorily and that, in particular, …automatic fire detectors function correctly in accordance with the recommendations in 45.4” BS 5839 Part 1:2002 Clause 39.2 c:
“The detectors shall be tested in place to ensure smoke entry into the sensing chamber and an alarm response.” NFPA Table (Test Methods) 13.g.1
“… the functional testing of the automatic fire detectors is, at the very least, to be carried out through the simulation of the relevant physical characteristics of fire outside of the detector (e.g. using test aerosols for smoke…)” DIN 14675:
“100% of all installed system components must be tested and, in the case of automatic fire detector tests, the alarm be triggered by simulating the characteristics of the fire at the detector.” DIN 14675:
“Maximum transport time is measured by introducing a small quantity of smoke or aerosol into the furthest sample hole and measuring the time between first introducing the smoke and observing a “reaction” at the detector.” FIA CoP
Standards used around the world specifically ask for functional smoke testing to be carried out in situ, with a stimulus that is representative of a real fire (in terms of material and smoke travel), and that does not adversely affect the detector after the test.

4. The problem… How to test?
Accessing hard to reach detectors or ASD pipes
Physical access
Lifting equipment needed
Detectors or pipes hidden behind architectural facia
What to test with?
Safe stimulus
Stimulus does not affect detector sensitivity
When to test?
Disruption to the business environment
Cordoned-off areas
Out-of-hours working for test technicians
Health and Safety concerns
Repeat every six months, once a year, never?

5. Current solutions… ASD systems Test Pipe Sometimes not fitted
If fitted, what stimulus is used?
Reliability and safety of stimulus
How to tell if the system has changed (transport time)
How do you prevent overdosing detector (contamination risk)?
How long does it take for detector to clear (repeat alarms)?
Point detectors
Difficult to access
What stimulus is used?
Repeatability / reliability of stimulus?
High-reach poles
Maximum height of 9 metres
Need to be kept close to vertical (accessibility?)
Supported by local and internatiuonal standards such as 5839, VDS, etc.

6. Scorpion
Scorpion is a smoke generation system that can be mounted on the ASD pipe or alongside a point detector
Enables a functional smoke test to be run from up to 100 metres (cable length) away
Smoke delivered in a controlled and repeatable manner
Allows measurement of transportation time to verify integrity of ASD systems
Successfully tested on the majority of ASD and point detectors

7. System Features Separate heads for Point and ASD systems
Up to 8 heads running off a wall-mounted controller
Both ASD and Point can be run off the same controller
Battery power provides security from accidental activation
Smoke and Clear times can be customised and saved on the panel
Manual transport timer for ASD systems
Star topology, 4-wire cable used
Up to 100m cable distance between control panel and head

8. Technologies Scorpion has been proven on the following technologies:
ASD
Light scatter
Particle counting
Cloud chambers
Point
Optical / photoelectric
Ionization
Conventional or addressable

9. Scorpion Benefits Improved Access Benefits
Connecting a remote Scorpion head unit to a convenient controller means:
Additional (and unsightly) ASD pipe runs eliminated
Access challenges avoided
Disturbance and disruption averted
Transportation time evaluation avoids testing every sampling point periodically
Time and Cost Saving Benefits 
Huge time savings from accessibility gains (even where physical access equipment was not required)
Transport time integrity evaluations
Sequential testing of multiple units from a single location delivers radical time savings
Out of hours working minimized or eliminated
Physical access equipment costs eradicated

10. Scorpion Benefits Appropriate Stimulus
Benign consistent particulate delivered in a controlled and repeatable manner
Reduces possibility of overdosing or contaminating detector through excessive stimulant application
Approved by world's leading ASD and Point detector manufacturers
