22.2.2 The + and - terminals inside the connection box must be connected to the Z+ and Z terminals
at the control panel.
22.2.3 The end of line resistors at the control panel should be discarded.
22.2.4 It is advisable to leave off the lid of the connection box, until all testing is complete.
22.3 Remote Lamp Connection
22.3.1 In some installations, particularly in floor voids, it is desirable to identify the area in which
water has been detected, with a remote indicator unit mounted above the void.
22.3.2 This can be achieved by wiring a K2103 remote lamp unit to the - and rem. terminals in the
K2106 connection box.
22.3.3 Only one remote lamp unit should be connected to each connection box.
22.4 Testing
22.4.1 Once all terminations have been made and the system is powered, the Hydrowire is ready
for testing.
22.4.2 Testing is best done by dipping the thumb and forefinger into a cup of tap water, shaking off
the excess drips and then gripping the Hydrowire firmly whilst rolling it slowly. This should
produce an immediate indication at the control panel.
22.4.3 Over wetting the Hydrowire should be avoided as a great deal of time can be wasted by
waiting for it to dry out.
22.5 General Checklist
22.5.1 Avoid excessive wetting.
22.5.2 Observe polarity of all connections.
22.5.3 Long lengths of Hydrowire may be susceptible to high levels of electrical noise. Keep
lengths short wherever possible and do not install close to other cables.
22.5.4 Do not twist, bend sharply, stretch, stand on or crush the Hydrowire.
22.5.5 Do not expose to surface temperatures above 70°C.
22.5.6 Use only recommended Hydrowire system components.
23. Hydrosense Probe Commissioning
This is best achieved by dipping the tips of the probe pins into a cup of tap water.
This should produce an immediate reaction at the control panel, the LED mounted on top of the probe and, if
fitted, the remote lamp unit and or sounder.
