Description

The SJE Rhombus Tank Alert I Alarm SJE1009207 features a robust design with a float-activated sensor that accurately detects high or low liquid levels in tanks. The alarm system includes an audible siren and a visual indicator, ensuring that users are promptly notified of any changes in the tank level. It operates on a 9V battery or can be connected to an external power supply, providing flexibility in installation and use.

This product is designed to be user-friendly, with easy-to-follow instructions for setup and operation. The durable plastic construction ensures long-lasting performance even in harsh environments.

INSTALLING THE ALARM & FLOAT SWITCH

1. Determine indoor mounting location for alarm panel.
2. Insert screw (supplied) at desired wall location. Note: Screw is to be located over wall stud or used with a wall anchor sized for a #8 x 1.25 self tapping screw.
3. Make sure power to alarm panel is disconnected.
4. Hang alarm panel using keyhole on panel back. Install second screw between tabs located on bottom of panel.
5. Mount the cord by placing the cord into the clamp as shown in Figure A.

6. Locate the clamp at the desired activation level and secure the clamp to the discharge pipe as shown in Figure A. 
   Note: Do not install cord under hose clamp.

   

7. Tighten the hose clamp using a screwdriver. Over tightening may result in damage to the plastic clamp. Make sure the float cable is not allowed to touch the excess hose clamp band during operation.

8. Bring cable leads back to alarm device and wire according to Figure B.
   Note: All hose clamp components are made of 18-8 stainless steel material. See your SJE-Rhombus supplier for replacements.
   Note: When used with a pump application, connect alarm to a circuit separate from the pump circuit. This allows the alarm to operate if the pump circuit fails.

   

9. Plug the panel in to apply power. The green "power on" light should come on.
10. Check installation by manually tipping the float. The horn and warning light should come on.
11. Move the horn silence switch to silence, the horn should silence while the red light stays on.
12. You must manually reset alarm after activation. Push horn button back to horn position and press "push to test" button. The light and horn should activate.
13. Test unit once per week to ensure proper operation.

14. Using the provided cable clasp, secure cord to outlet as shown in Figure C. Use existing receptacle faceplate screw and supplied washer.
