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.
LED

is illuminated during the silence period.
Terminal block
(3)
is custom wired and should not be modified unless instructed by AirTest or it's
an authorized representative.
The 2 header pins
(4)
are connected to the front panel push button via an IDC plug.
