4.7 After a power failure

After any power failure, the user should check the system clock. While system parameters are maintained in memory, the system clock is backed-up by a limited-capacity button cell

battery.

4.8 Appendix A – Quick Set-up

IMPORTANT: To properly and effectively program the system you must conﬁgure the Sensors, Relays, Zones and Signals. If the user has not entered any parameters, the system

WILL NOT be monitoring the sensors or controlling the ventilation system. The relays will be in the not actuated state and the horn and strobe outputs will be off.

1. Conﬁgure System: allows the installer to set the time of day, day of the week, load the default conﬁguration, and change the password.

2. Conﬁgure Sensors:denestheSensortype-CO,NO2,EXorNoneandsetsAlarmLevel,WarningLevel,andSensorRange

3. Conﬁgure Relays, Horn and Strobe: deﬁnes operation as Normally Off or On, Delay Time, Minimum Runtime – this applies to all three relays as well as the horn and strobe.

Note: The Delay Time default is 1 minute. If the duration of a test procedure or gas exposure is less than 1 minute, the relays, horns and strobes may not engage even though the

DVP-120 display and the sensors respond. When testing the system disable the delay (set Delay Time to zero minutes/seconds).

4. Conﬁgure Zones: deﬁnes Sensor Input & Relay/Alarm Output and sets up the sensor Groups (set of sensors of same type and output within the same zone) - Sensor type, Sensor

Number, Rising Trip point and Falling Trip point

5. Conﬁgure Signals: deﬁnes the output of the Alarm, Warning and Trouble Signals (Buzzer, Horn and Strobe) as On, Off, Intermittent, Continuous, etc.

Note 1: The default Password is 1234. If the password has been changed and/or lost:

Note 2: When entering multiple digit values the Up arrow ( ↑ ) acts as an enter key and it is not necessary to enter all allowed ﬁelds. Any other key is ignored or cancels the current

parameter change.

Note 3: The MENU key will cause the system to shift to the Conﬁguration Menu. The up and down and left and right arrow keys will scroll through all conﬁguration parameters.

Setting the System Conﬁguration

The conﬁguration menus can be entered from normal mode by pressing the MENU key. While in conﬁguration mode, the user can review all conﬁguration parameters to check the current

operating conditions.

Figure 4-1 Hardware Summary

The MENU key is also used to return to a higher-level menu, exit the conﬁguration menus and ﬁnally return to normal mode.

When exiting from the menu system to normal mode, if any conﬁguration changes have been made, the panel will ask whether changes are to be saved.

Figure 4-2 Save Conﬁguration? Prompt

Pressing the zero (0) key at this point will cancel all changes except time and day of week. Pressing the one (1) key will save all changes to memory, and the changes will then become

immediately effective in controlling the ventilation system.

The numeric keys are used to change the particular parameter displayed. The underlined numeral, or space, on each display indicates what will be changed by the numeric keys. The left

and right arrow keys will enter the particular submenu and scroll through the items of the same type where appropriate, (e.g., enter the Conﬁgure Sensors submenu) and scroll through the

parameter lists for the existing sensors. The up arrow key scrolls through the menu entries in the order listed here, while the down arrow key scrolls in the reverse order.
