TraceTek TT-FLASHER-BE independent battery-powered light module, EX | 300 m
nVent RAYCHEM TraceTek TT-FLASHER-BE is an inexpensive, battery-powered device that emits an easy-to-see flashing light signal whenever a TraceTek sensor cable or probe detects liquid. Because it is completely self-contained and requires no external connections, installation is simple and inexpensive. It monitors up to 300 meters of sensor cables or up to 1 fuel detection probe TT-FFS.
Spark safe and suitable for use in hazardous areas
TT-FLASHER-BE runs on two long-life "AA" alkaline batteries. Since the available voltage is limited to 3.3 volts and TraceTek sensor cables and probes require a very limited amount of energy, this device is approved for use in hazardous areas. The sensor cables, probes and the TT-FLASHER-BE itself can be installed in most hazardous areas (see the approvals section for details). TT-FLASHER-BE can monitor any sensor cable from the TraceTek family TT3000, TT5000, TT5001 and TT7000. The device will also monitor a fast-acting fuel detection probe nVent RAYCHEM TT -FFS. No external ZENER guardrails are required; sensor cables and probes are connected directly to TT-FLASHER-BE.
Visual signaling only
TT-FLASHER-BE provides simplicity of operation at the highest level: A flashing RED light indicates that a leak has been detected. There are no external relay signals or connections to other alarm systems. A TEST button makes it easy to check battery voltage and sensor cable integrity.
TT-The FLASHER-BE will signal a low battery condition with a double flash for about 1 month before the battery voltage drops to an unusable level. However, batteries should be replaced as part of an annual preventive maintenance schedule.
Compromise: simplicity vs. human factors
Because TT-FLASHER-BE is designed to be visible to the operator, it is not suitable for all installations. No relay contacts or other means of remote alarm signaling are provided. For the system to be effective, the TT-FLASHER-BE must be visible and facility personnel must respond to the visual signal. Similarly, if the battery is completely discharged, TT-FLASHER-BE will not be able to signal a leak.
The TT-FLASHER-BE module has been approved for use in hazardous areas. The module can monitor intrinsically safe TraceTek sensors placed in hazardous locations, as shown below.
The light module monitors sensor cables placed in drainage pipes under aboveground tanks. The TT-5000 series sensor cable reacts to hydrocarbons, it does not react to water. The same solution can be made under pipelines buried in the ground.
TraceTek TT-FLASHER-BE also works well as an independent leak detector for double-bottomed / double-walled tanks, whether buried in the ground or mobile.
