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 Figure B- 14.
12.
Thread the detector’s cable through the wiring hole.
13.
Connect the detector’s cable to the terminal block as shown in Figure B- 37.
14.
Replace the PCB inside the back cover making sure that it clicks into place.
15.
Before permanently mounting the detector, place a wet rag over the terminals
(located on the bottom of the detector).
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 detector’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.
The LED indicator does not function when the tamper switch is closed.
16.
Fix the detector to the floor using the two screws, spacers and wall anchors provided.
Alternatively, you can fix the detector to the floor using the double-sided adhesive tape
provided – see the following section.
17.
Close the front cover of the transmitter.
Detector Installation with Double-sided Adhesive Tape
If using double-sided adhesive tape to install the detector, 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 detector.
Do not touch the adhesive with your fingers.
3.
Peel away the backing from the other side of the adhesive tape.
4.
Fix the detector to the floor by firmly applying pressure for a few seconds.
