Communication with
the control panel
The water sensors as well assending an alarm signal if the electrodes are immersed in water, also
periodically send a signal (IOK) to the control panel, indicating that they are present and functional. if
this signal is not received on schedule by the control panel, an alarm is
triggered. The water sensors also have an internal battery check, made on a
regular basis. An alarm will be triggered by a water sensor
with low battery voltage.
NOTE :
After detecting water, the water supply will be shut off. Make sure the sensor
is completely dry. If water has gotten inside the sensor, you must replace it.
To restore the water supply, press the
Open
button on the remote control (which
may take a few moments to respond) or the
Reset
button on the control panel.
The control panel has two main connection points. The main control panel is
also equipped with a concealed push button to be used during programming and
synchronization only.
Jacks (2) 3.5mm stereo connected in parallel for one or two shutoff
valves.
°The jacks are equipped with integral switches which close when a valve is plugged in. The control circuit will issue an
alarm if a valve becomes disconnected. In the event that only one valve is deployed, a dummy plug must be inserted in
the other jack.
Alarm system connection
For units configured for use with home alarm systems, the 886E control is fitted
with 2 relays. One alarm relay, which outputs NO (normally open) / NC (normally
closed) contacts to the alarm system in the event of a shutoff alarm, and a second
relay : a low battery warning - that outputs a contact to the alarm system if a low
battery signal is received from a water sensor.
Alarm output contacts from the 886E operate when there is an alarm that closes the valve – not when
the valve is deliberately closed by the rem ote.
Terminals are provided to connect with a local alarm system. The Alarm Input closes
when the alarm system is set -as when leaving the residence. After a delay of 2 hours
(to allow completion of washer/dishwasher cycles) the valve should close. It will
reopen when the alarm input contacts open.
If Alarm system is not used, no
connections need to be made to these
terminals
