C5. Fiberglass Reservoir Sensor (con't) For RS -10 Reservoir Sensors: • Pipe fitting connections provide quick, easy access to sensor and reservoir without disconnecting any electri- cal or piping connections. • Sensor includes riser pipe cap with a length of flexible conduit which is connected to a NEMA 4 or NEMA 6 electrical junction box (contractor supplied). • PVC riser pipe cap slips on and off the PVC fitting in- stalled on top of riser pipe.

This should be tested periodically. • To test, simply push button on top of cap. Light shows green for liquid in reservoir, red for no liquid in reser- voir. No light indicates loss of battery power. 16 C6. Electrical AWARNING • Do not place intrinsically safe sensor wiring in the same conduit as non -intrinsically safe wiring. DO • Make certain all electrical work conforms to local codes. • Wire reservoir sensor to the control panel using wiring specified on control panel wiring diagram. CAUTION: Place wiring in water tight conduit and junc- tion boxes (to maintain leak detection capability). C7. Testing To simulate low liquid level condition: • Remove sensor from fiberglass reservoir. To activate low level alarm: • Remove sensor from fluid in reservoir. To activate high level alarm: • Fully immerse sensor into a bucket of water. C8. Reservoir Leak Detection What to do for an alarm condition: • Remove the riser cap. • Extract reservoir sensor. • Use dipstick to measure reservoir liquid level: ❑ If dipstick measurement is 1.25" (2" for tanks 15,000 gallon capacity or larger) or less, reservoir has drained, indicating a low level alarm. ❑ If dipstick measurement is 14" or higher, the high level alarm has been activated. For a Low Level Alarm: • Refill the reservoir to 1/2 full. • Continue monitoring. For a High Level Alarm: • Remove liquid from reservoir until it is %2 full. • Continue monitoring. If alarm occurs and reservoir level is normal: • Consult your local electrician. ❑ Control panel is improperly wired or has a defec- tive component. • See section D9 on Control Panel False Alarms. Important: If a second low level or high level alarm occurs, call Fluid Containment Field Service. Phone number listed on page 2. is • •
