Product quality and reputation are paramount to us at Starlite Security Devices, LLC. We would like to offer you a snapshot of the testing that randomly selected TW-8100 units are subjected to in order to help us determine the resilience of our product.
1) At approximately 68 degrees Fahrenheit the TW-8100 is connected to a service valve on a copper tube that has been charged to 240psi with nitrogen.
2) All leads are metered to make sure all internal resistors are within tolerance.
3) Two leads are connected to a zone of a security control panel (various brands of control panels are used) which is programmed for fast loop response. The security control panel is armed and remains armed throughout the duration of the testing procedure.
4) The TW-8100 is then heated until the core temperature reaches approximately 195 degrees. While at this temperature, all leads are metered to make sure all internal resistors are within tolerance, then the TW-8100 is subjected to multiple high impact shocks and then placed on a motorized table to be vibrated for approximately 15 minutes. The vibration is frequency is swept up and down continuously from 1000hz to 6000hz.
5) The TW-8100 is then immediately submerged into cold water for approximately 60 seconds, removed and subjected to multiple high impact shocks.
6) All leads are metered to make sure all internal resistors are within tolerance.
7) Next the TW-8100 is thermally shocked by reducing its temperature to approximately –5 degrees Fahrenheit for approximately 14 hours. While at this temperature, all leads are metered to make sure all internal resistors are within tolerance, then the TW-8100 is subjected to multiple high impact shocks and then placed on a motorized table to be vibrated for approximately 15 minutes. The vibration is frequency is swept up and down continuously from 1000hz to 6000hz.
8) While the TW-8100 is still cold, it is thermally shocked again by reheating it until the core temperature reaches approximately 195 degrees Fahrenheit. While at this temperature, all leads are metered to make sure all internal resistors are within tolerance, then the TW-8100 is subjected to multiple high impact shocks and then placed on a motorized table to be vibrated for approximately 15 minutes. The vibration is frequency is swept up and down continuously from 1000hz to 6000hz.
9) All leads are metered to make sure all internal resistors are within tolerance.
10) Finally, the TW-8100 is removed from the service valve in order to make sure that the internal contact will still open and activate the security control panel that it is connected to.
We are proud that out of all of the batches that we have produced, this testing procedure has not been able to cause a false alarm from any unit tested, but every unit has caused an alarm in step 10 (as it should) when removed and all metered resistors have been within tolerance.
