Mounting the Activation Module
The activation module receives a signal from
the flood sensor when a discharge is detected. If the
discharge meets the conditions of a qualifying event,
the normally open contact is closed to provide a signal
to the BMS input terminal.
1. Use the Phillips screwdriver to remove the dust
cover from the flood sensor.
2. Remove the O-ring from the cover and place it on the
activation module to create a seal between the module
and the flood sensor.
3. Attach the activation module to the flood sensor with
the four attachment screws.
NOTICE
Retain the dust cover to protect the flood sensor during
temporary instances when the activation module may
need to be removed or replaced.
Custom Flood Sensor Settings
DIP switches on the activation module can be used to specify the wet threshold (sensitivity to
water discharge) through SW1 and the timer delay (duration before alarm) through SW2. Scan
the QR code for more information.
Connecting the Module Cable to the BMS Controller
The 4-lead conductor module cable should be attached to the BMS controller to transmit a normally open contact
signal and provide power to the activation module. The contact signal closes when a discharge is detected. Follow
the procedures below to connect the cable, ground wire, and power adapter (optional) to the controller. (See the
wiring diagram for visual reference.)
To wire the cable to the controller
1. Use the wire stripper to cut away enough insulation
to expose 1 to 2 inches of the conductor wires.
2. Insert the white and green wires into the input terminal.
Insert the red wire in the power terminal. (A power
source ranging from 12V to 24V is required.)
NOTICE
Either the BMS power source (ranging from 12V to 24V)
or the 24V DC power adapter provided can be used.
With each power source, an earth ground connection
is required.
If using the optional power adapter, skip to the next set
of instructions. Be sure to use the ground wire provided
if there is no other earth ground on the BMS controller.
3. Insert the red wire in the power terminal. (A power
source ranging from 12V to 24V is required.)
4. Insert the black wire in the ground terminal.
The earth ground must be connected to the BMS
controller before the flood sensor is put in operation.
To use the optional 24V DC power adapter
Distinguish the positive wire from the negative one.
The positive wire has white stripes and must be inserted
into the power terminal; the negative wire, into the
ground terminal.
1. Connect the positive power adapter wire (black with
white stripe) to the red wire of the activation module
cable and insert the wires into the power terminal.
2. Connect the negative power adapter wire (black with
no stripe) to both the black wire of the activation
module cable and the ground wire (if needed) then
insert the wires into the ground terminal.
3. Plug the power adapter into a 120VAC, 60Hz,
GFI-protected electrical outlet.
The flood sensor LED is steady green when the unit
is ready.
