AirTest Model CN9000 Feature Module

This custom feature module incorporates a timing circuit, output relays and external input/output

wiring terminal block.

Silence Timing Circuit

When the front panel pushbutton marked "Silence" is pressed the timer circuit silences the

audible horn for a period determined by the position of trim pot (1). After the time period expires

the audible circuit alarm will be enabled if the system detects a gas level above the Relay Trip

Point (RTP). The timer is adjustable from 0 to approximately 20 minutes. The image below

shows the trim pot set to offer a silence period of approximately 12 minutes.
