7. Choose a mounting location. The transmitter should be positioned in a vertical position high on the
wall in order to optimize reception. The sensor should be placed in a position where water will
accumulate rapidly in the event of a flood.
8. Before permanently mounting the unit, test the transmitter from the exact mounting position.
9. To remove the PCB, press the PCB release tab, carefully lift the board and slide the board away from
the back cover.
Caution: When handling the PCB, do not apply pressure on the antenna.
10. Knockout the wiring hole in the back cover.
11. Mount the back cover to the wall using two screws and replace the PCB. Use #6 x 3/4" countersunk
wood screws (ISO 7050 - ST3.5 x 22) or similar countersunk screws so that the screw head will not
touch the PCB – see p. 97, Figure B- 8.
12. Thread the sensor’s cable through the wiring hole.
13. Connect the sensor’s cable to the terminal block as shown in Figure B- 29 (p. 112).
14. Replace the PCB inside the back cover making sure that it clicks into place.
15. Before permanently mounting the sensor, place a wet rag over the terminals (located on the
bottom of the sensor).
The EL-2661 transmits an alarm 30 seconds after detecting the presence of water. This 30-second delay
verifies that the alarm is caused by a significant amount of water and is designed to prevent false
alarms caused by humidity or condensation. Similarly, the EL-2661 sends a restore signal 30 seconds
after the sensor’s terminals are dry. When the Tamper switch is open, the 30-second delay is canceled
in order to speed up the test procedure. Make certain that the LED is lit during transmissions.
Note: The LED indicator does not function when the Tamper switch is closed.
16. Fix the sensor to the floor using the two screws, spacers and wall anchors provided. Alternatively, you
can fix the sensor to the floor using the double-sided adhesive tape provided – see the following
section.
17. Close the front cover of the transmitter.
Sensor Installation with Double-sided Adhesive Tape
If using double-sided adhesive tape to install the sensor, perform the following procedure for best results:
1. Clean all surfaces using a low strength solvent such as isopropyl alcohol to ensure that the surfaces are
clean, dry and grease-free.
2. Peel away the backing from the pieces of adhesive tape and attach them to the underside of the sensor.
Note: Do not touch the adhesive with your fingers.
3. Peel away the backing from the other side of the adhesive tape.
4. Fix the sensor to the floor by firmly applying pressure for a few seconds.
Repeater (EL-2635)
The EL-2635 is a wireless repeater designed to extend the range of wireless devices registered to the Control System.
Up to four repeaters can be registered to the Control System with 32 transmitters registered to each repeater. The
repeater is powered by either 9VACwith a 6V rechargeable backup battery pack or 12VDC. Registration and
maintenance tests are performed using a plug-in LCD programming keypad that provides a comprehensive interface to
the repeater.
