NOTE: Oxygen sensor readings is an exclusion for 4-20mA output i.e. its reading is not considered while computing output value
for 4-20mA output.
Next, the output mode can be set to PEAK or SCALE.
PEAK – In this mode the gas reading active in the zone (except for the oxygen) corresponding to highest mA output is used to
control the analog output assigned to the specific zone. In this case, any active gas reading, that is part of the zone will be taken
in consideration, and the sensor reading corresponding to highest mA output will be used to control the analog output. E.g. If a
CO and NO2 sensor is assigned to a zone and CO Sensor reading is 50ppm (which corresponds to 8mA) and NO2 sensor reading
is 10.0ppm (which corresponds to 12mA) then 4-20mA or Analog output assigned to the zone will output 12mA.
SCALE – In this mode, the 4-20mA value for all detectors added to a zone are computed (for all sensor types except oxygen), and
the output is the average of the 4-20mA value for all detectors assigned to the zone. E.g. If a CO and NO2 sensor is assigned to a
zone and CO Sensor reading is 50ppm (which corresponds to 8mA) and NO2 sensor reading is 10.0ppm (which corresponds to
12mA) then 4-20mA or Analog output assigned to the zone will output 10mA.
To select the output mode for 4-20mA output, select OUTPUT MODE from the 4-20 O/P menu and press ENTER. Then, select
PEAK or SCALE from the 4-20 O/P MODE menu and press ENTER. The display will return to the 4-20 O/P menu and the output
mode selection will be updated as shown in Figure 4-29.
When the status of the zone is TROUBLE then 4-20mA output assigned to corresponding zone will switch the output to 20mA.

The DVP-1200 includes 4 standard onboard relays with the option to add an additional 4 onboard relays. Additionally, remote
relays can be added to the system. It also has an onboard buzzer and includes 4 outputs designed to operate standalone
horn/strobe units. This section includes directions to configure those components.
From the CONFIGURE SYSTEM menu, select CONFIGURE RELAYS, H/S, BUZZER? and press ENTER. The display will show the
CONFIGURE RELAYS, H/S, BUZZER? menu as shown in the images below.
