Flood Detector (EL-2661)
The EL-2661 is an indoor flood detector and transmitter intended for installation adjacent to hot
water heaters, washing machines, central air conditioner condenser pans and anywhere prone to
damage caused by an undetected water leak. In the event of flooding or leakage, the EL-2661
notifies the Control System after detecting the presence of water for a period of at least 30 seconds.

Batteries must be replaced within seven days of receiving a low battery indication. The
estimated battery life is 4 years (avg. 25 activations per day).
Installation Procedure
1.
To open the transmitter’s housing, insert a small screwdriver at the bottom of the unit
between the front and back cover and twist the screwdriver to release the cover.
2.
Remove the divider separating the battery from the contacts on the battery holder. When
you apply power and the tamper switch is open, the EL-2661 enters Test mode during
which a transmission is sent every few seconds. You can terminate Test mode by closing
the tamper switch.
Test mode is automatically terminated after approximately five minutes.
Due to the occurrence of voltage delay in lithium batteries that have been in storage, the
batteries may initially appear to be dead. In this case, leave the unit in Test mode for a few
minutes until the battery voltage level is stabilized.
3.
From the Programming menu, select Devices, Zones [911].
4.
Select the zone to which you want to register the transmitter; the system initiates Registration
mode.

6.
After registration, press the EL-2661’s tamper switch to terminate Test mode.
7.
Choose a mounting location. The transmitter should be positioned in a vertical position
high on the wall in order to optimize reception. The detector 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.
When handling the PCB, do not apply pressure on the antenna.
