Zone Controllers (LD310)

Key Features

Accommodates:

up to 300 feet (91 meters) of conductive fluid sensing cable and/or spot detectors, or

up to 210 feet (64 meters) of chemical sensing cable

Visible alarm indicator

Two Form C output relays for leak and fault alarms

Audible and visible alarm notification

Adjustable leak alarm sensitivity thresholds

Configurable for supervised or non-supervised operation

Distinguishes normal conditions from alarm conditions

Quickly returns to normal

Included Equipment: LD310 controller, leader cable, end-of-line (EOL) terminator

Additional Requirements: Power supply WA-DC-5-ST, sensing cable and spot detector (as needed for application)

Power: Requires an isolated power supply.

5VDC Isolated (±10%) @ 100mA max; requires RLE power supply WA-DC-5-ST (not included)

Inputs

Leak Detection Cable: Compatible with all SeaHawk sensing cables as well as SD-Z and SD-Z1 spot detectors (not included)

One Cable Input: Requires 15ft (4.6m) leader cable and EOL terminator (included)

Maximum Sensing Cable Length: 300ft (91m) of conductive fluid sensing cable, or 210ft (64m) of chemical sensing cable

Detection Response Time: When used with conductive fluid or chemical sensing cables, less than 20sec; 10sec typical.
