General Information

The GAI-Tronics Model 670-002 24 V dc Explosion-proof Speaker Station provides safe and clear
communications in hazardous areas, even in high-noise situations. This model is NRTL certified for use
in the US and Canada for the following areas: Class I, Div. 1, Groups C and D; Class II, Div. 1, Groups
E, F, and G; and Class III, Div. 1.

The Model 670-002 station enclosure is fabricated from cast aluminum and is suitable for indoor use. If
the station is to be mounted outdoors, it should be housed in a GAI-Tronics Model 10444-003
Weatherproof Non-metallic Enclosure. This enclosure is rated NEMA 4X, and can be purchased
separately.

This installation manual provides instructions on both the placement and mounting of the station. Refer
to Pub. 42004-183, which shows the conduit installation and station wiring details necessary to maintain
the explosion-proof integrity of the station.

WARNING

Explosion Hazard – Do not connect or disconnect equipment unless power

has been switched off or the area is known to be non-hazardous.

Installation

Whether installing an entire system or only an add-on station, consult the 24 V dc system layout diagrams
at the end of this manual. These figures, used in conjunction with the station installation information and
the cable layout guide, should provide all the information necessary to install the Page/Party

®

stations.

These figures do not show an explosion-proof station; however, the basic points of the system layout and
design still apply.

NOTE

A separate power feed is recommended for Page/Party

®

stations in Div.1 areas. With a

separate power feed, the Page/Party

®

stations can be shut off for maintenance without disrupting the

power supply to the other equipment in the Div. 1 area.
