DFL detector
How to replace the batteries
1.
Insert a slotted screwdriver to the slot at the bottom of the detector and remove the cover.
2.
Remove the batteries and place new batteries. Observe polarity! The green LED will flash once.
When placing new batteries the detector warms up for 3 minutes - the tamper switch is ignored during this time.
3.
Replace the cover.
4.
Test the DFL.
How to install the DFL
You can mount the detector using the supplied screws or stickers. In any way, the water sensor must be placed as near as possible to
the surface where water can leak, or wherever else water can leak. The detector must be mounted where leaking water cannot reach it,
at least for a time which allows the detector to transmit a flood event.
To mount the detector using screws, do the following.
1.
Insert a slotted screwdriver to the small slot at the bottom of the detector and open the enclosure.
2.
Remove the batteries.
3.
Remove the PCB (printed circuit board): insert a slotted screwdriver on any side of it, push it gently and lift it over the retainers.
4.
Remove the knock outs on the back of the enclosure (no. 7 in the figure on the first page) and fix it to the surface using the screws.
Make sure to use the tamper's screw (no. 7 in the figure on the first page) for the DFL to
alert when it is removed from the mounting surface.
When using the stickers to mount the DFL, the tamper will not alert when it is removed
from the mounting surface.
5.
Replace the PCB and insert the batteries. Observe polarity! The green LED will blink one time.
6.
Set the DIP switch; see how below.
7.
Connect the two wires of the sensor to the terminal block (no. 5 in the figure on the first page).
8.
Fix the sensor to a firm surface vertically, with the sensor facing down, as seen in the figure on the first page (no. 9). Securing the
cable with clips (not supplied) is recommended.
9.
Enroll the DFL and test it; see the alarm system's installation guide for details.
10. Test the sensor; see below how.
11. Close the detector's enclosure.
