Patol 700-811 Digital LDM-519-DDL 2km Output Module - Legrand Enclosure

The LDM-519-DDL, with Location Display, combined with the programmable relay output module offers nine individually programmable relays used to provide location identification outputs if a Fire condition occurs along the installed LHDC.

The result of the combined units is a system designed to monitor a length of Digital Linear Heat Detection Cable (LHDC) for both Fire condition and Fault status (open circuit). It has a 3½ digit LCD which activates on Fire condition and displays the distance into the zone the alarm has occurred up to 2km (1999m). The unit has an adjustment to accommodate interposing cables and has signalling of Fire and Fault status by means of volt free contacts.

These contacts can then be integrated with an operator panel, automation system or connection to fire zone trigger circuits or addressable interface modules.

Key Features:

• Display of Alarm Location: Distance in metres
• Fault monitoring of LHDC for open circuit conditions
• LED indication of Fire, Fault and Supply status.
• Test & Reset functions
• VFC outputs for Fire & Fault conditions – Selectable
• IP65 Rated Shock Resistant Polystyrene
• RS 232 (separate cable required)
• Programmable Relay Output Contacts
