The Type 7011 flame detector comprises an outer housing within which is located an inner polycarbonate enclosure. The outer housing is connected to an air blower such as to keep a positive air pressure around the inner unit's sensor windows. A pressure switch signals a fault on air failure.
An adjustable bracket permits alignment in both vertical and horizontal planes. The inner module's fascia and back-box have a high level of ingress protection and are rated at IP66.
Removal of both outer lid and inner fascia provides access to terminals and maintenance features. Cable connection is at plug-in (two part) screw terminals, permitting PCB module removal without wiring disconnection.
The unit has open collector transistor type outputs which may be directly used for fire and fault signaling in "Low Power Mode". Alternatively "Relay Mode" may be selected which provides volt free change over contacts.
Sixteen LEDs provide indication of the dynamic status of the eight flame detection channels. These are principally used as commissioning and maintenance aids. During normal operation, in order to minimize supply current, the indicators are usually disabled by means of PCB jumpers.
Located at the rear of the fascia unit is a six pole SIL program switch for setting the sensitivity level and optical axis focal ‘zoom’ characteristics of the device.
