Product description
With this module, each sensor channel of the Water Alarm Central gets its own switching contact. This offers additional options, e.g. triggering an acoustic alarm on channels 1, 2 and 3 and activating a telephone dialer in the event of a message on channel 4. Many other combinations are possible.
Applications
Voltage-free changeover contacts
This provides you with a voltage-free make or break contact for each individual channel. For example, it is possible to switch on a device in the event of an alarm on channel 1 and to disconnect the voltage supply to another device in the event of an alarm on channel 2. Another example: in a cellar there are two sensors at different heights. If the lower sensor detects water, the alarm lamp on channel 3 switches on and as soon as the upper sensor also becomes wet, channel 4 activates a GSM alarm. Explanation: This module is built into the
Water Alarm Central, so that it has its own switching contact per channel. The alarm contact that is already present gives a message for all channels when at least one of these sensors gives an alarm.
