Overview
ExP-1/-5 Explosion Proof Page/Talk Wall Stations
Guardian's Page/Talk Systems provide reliable and easy to use paging and communication within
industrial environments such as plants, mills and factories. Individuals can be paged from any
station and two or more persons can communicate on any available Talk line.
The Models ExP-1 (Single-line) and ExP-5 (Multi-line) stations described in this manual are designed
for use in Class I & II, Division 1 hazardous locations. Each ExP-1/-5 Wall Station provides up to
twelve watts of paging power for an external loudspeaker. A push button switch on the faceplate
puts the station into paging mode.
In order to avoid acoustical feedback from a loudspeaker receiving a signal from the station, a jumper
on the circuit board provides for the speaker to be muted when the Page button on the faceplate is
pressed. Group muting is also available for the same purpose, this feature mutes adjoining speakers
when the page button on any station in the group is pressed.
Guardian's Page/Talk stations and related equipment are compatible with systems provided by most
other manufacturers.
