Transmission Contact Switch • Automatic telephone dialer: ❑ Typically requires only a contact switch to activate dialing function. ❑ Is plugged (or wired directly) into an electrical out- let for power source. • Dialer power source is not supplied by control panel. ❑ With power to control panel, normally -closed con- tacts are at terminals 3 and 4. ❑ Terminals will open - providing the switching mecha- nism to activate dialer - when control panel goes into alarm mode.

CAUTION: Place wiring in watertight conduit and junc- tion boxes (to maintain leak detection capability). • Typical wiring diagram is provided for accessories re- uiring power such as light beacon. Contacts (see Figure B, page 30) can provide 120 volts AC. ❑ Optional warning device must be rated for 300 watts or less. D5. Alarm Bell Silence Button • Depress Bell Silence Button on control panel to silence alarm bell. ❑ The alarm bell will activate again if second alarm condition occurs. D6. Normal Operation • If"NORMAL" light is continuously illuminated, it means liquid level is in normal range. 18 • Inner and outer walls are leak -free if liquid level in reser- voir is stable. • Liquid level in reservoir will fluctuate as the tempera- ture of incoming stored product changes. • Reservoir is designed to provide adequate capacity for normal thermal expansion and contraction. D7. Testing and Maintenance Important: Check control panel warning system at least once per year. • Depress "TEST BUTTON" switch on front of control panel to verify that each internal circuit is operational. ❑ This does NOT test operation of monitoring sensors. • Use troubleshooting guide (See Figure A, page 29) to diagnose faulty circuit in control panel. • Contact Fluid Containment Field Service for control Panel replacement parts. Phone number listed on page 2. D8. Leak Detection • In the unlikely event reservoir totally drains: ❑ Control panel alarm will activate. ❑ Warning light will illuminate. ❑ Alarm bell will sound. ❑ Transmission contacts will activate any accessory alarm device. • Alarm bell can be silenced by pushing Bell Silence But- ton. ❑ "WARNING" light will remain on. ❑ "NORMAL" Light is off- 0 ff • See section C8 - Reservoir Leak Detection. D9. Control Panel False Alarms • Occur when panel goes into alarm mode, but reservoir liquid level is still in normal range. • Typically result from failure of an electronic component inside control panel. • To maintain the "NORMAL" condition: ❑ All electronic components must function properly. ❑ Any electrical component failure will result in an "ALARM" condition. Important: Refer to troubleshooting guide on page 29 to identify specific problem.
