The Aqualarm ZLM-500 zoned locating module is used to monitor combined leader / jumper and detecting cables for water leaks and cable damage.
The Zoned Locating Module generates Pulsed Echo Radar signals, which are transmitted along the entire length of the Leader / Jumper and Detecting Cables. When any change in the characteristics of the cable, whether water detected or open circuit, occurs, these are compared to pre-programmed limits and when these limits are exceeded, an alarm signal providing the meterage reading accurate to +/- 1metre, will be sent to the designated ‘Aqualarm’ master control panel.
The ZLM-500 is typically used for larger areas to monitor detection cable per zone. The module converts a zoned control panel into a locating system within a network-designed system when connected to either an Aqualarm i-Zone control panel or One-Touch system.

Power to the ZLM-500 is generated via the Aqualarm CAN network. A local, volt-free alarm contact is provided, and other alarm contacts are available from the Aqualarm master control panel.
