Strobe Turn On Delay; Strobe Minimum On Time; Configure Zones Submenu; Zone Controls - Macurco DVP-120 User Instructions

Notice that the strobe number, 5, is underlined. This indicates that the digit keys can be used to jump to a particular relay, horn or
strobe. The relays are numbers 1, 2 and 3; the horn is number 4 and the strobe is 5.
3.3.6.2

Strobe Turn On Delay

The default turn on delay is one minute and the maximum allowed value is fifteen minutes.
3.3.6.3

Strobe Minimum On Time

The default minimum on time is zero and the maximum allowed value is fifteen minutes.
3.3.7

Configure Zones Submenu

The DVP-120 ventilation control can support up to three zones. The zone functionality makes the DVP-120 very flexible. For example,
each zone can be configured to monitor a separate set of four sensors and control a single relay.
Another control scheme uses one zone to monitor all sensors and turn one relay on at a relatively low gas concentration. A second
zone monitors the same sensors and turns on a second relay if the gas concentration reaches a higher level. The third zone can also
monitor the same relays turning the last relay on as a signaling device to a live monitor station, as well as turning on the external horn
and strobe, under the assumption that the ventilation system is not working.
In addition to controlling the relays based on the gas concentration, each zone can have a timed function, e.g. turn on low volume
ventilation fans at 7:00 AM and turn them off at 8:00 PM.
The default Ventilation Controls are:

Zone 1 controls Relay 1

Zone 2 controls Relay 2

Zone 3 controls Relay 3
3.3.7.1

Zone Controls

This display example shows that Zone 1 is configured to control all of the relays plus the horn and the strobe. Each of the relays, the
horn and the strobe can be removed from (or added to) the zones control by pressing the indicated digit key. By default, Zone 1 will
control Relay 1, Zone 2 will control Relay 2 and Zone 3 will control Relay 3.
Definitions:

Zone – Defines Sensor Input & Relay / Alarm Output

Group – Set of Sensors of same type and output within the same zone.

Average – Activation based upon an average of sensors in a group

Voting – Number of sensors needed to be above trip point to activate output

Quorum – Number of sensors need to vote, 1 = any sensor.
