ZoneGuard Single Channel Fixed Gas Detection from Sperian Biosystems
(discontinued January 1, 2011)

The ZoneGuard is a microprocessor based fixed gas detection system designed to accept the input from a single oxygen, combustible or toxic sensor. ZoneGuard systems are designed to provide continuous round-the-clock monitoring for a variety of common atmospheric hazards including oxygen deficiency and/or enrichment, combustible gases and vapors, and specific toxic contaminants such as carbon monoxide (CO), hydrogen sulfide (H₂S), sulfur dioxide (SO₂), chlorine (Cl₂), phosphine (PH₃), and nitrogen dioxide (N0₂). Sensors may be integrally mounted to the ZoneGuard controller housing, or remoted up to 50 feet away from the controller. Remote detector assemblies are available in explosion proof or non-explosion proof versions.

All normal procedures, including fully automatic calibration adjustment, are controlled with a single button located at the controller.

Other standard features include two independently adjustable alarm set points, built-in audible alarm, easily-read, backlit LCD display, bright LED alarm light indicators, and relay contacts for low and high alarm conditions. Optional accessories include externally mounted high intensity strobe lights and high intensity horn.

Weather Protection

Controller housing: NEMA 4X enclosure (IP rating of 654)

Dimensions

ZoneGuard controller: 10" (25 cm) x 7.5" (19 cm) x 5.25" (13 cm)

Wiring:

For oxygen remote detectors use (minimum) 22 gauge AWG, 6 conductor twisted-pair shielded with drain.
For toxic use (minimum) 22 gauge AWG, 4 conductor twisted-pair shielded with drain.
For combustible use 18 gauge AWG, 4 conductor twisted-pair shielded with drain.

Each ZoneGuard system includes the controller with all standard alarms, relays and electronics installed in a NEMA 4X fiberglass housing, and sensor. When remotely mounted sensors are specified the components provided include both the sensor and remote detector housing. Specify the type of sensor and whether the sensor is to be housed in an explosion proof or non-explosion proof sensor housing at the time the system is ordered. (Combustible sensors may only be mounted in explosion proof remote sensor housings.) Note: conduit, wire and other components necessary to connect remotely located sensors with the instrument controller are not included.
