Frequently Asked Questions About The DWA-S Sonachron Program Timer

1.  

Can the DWA-S be used as both an on/off controller and a signalling device at the same time?

The DWA-S Sonachron Program Timer is designed to operate as either an on/off controller or a signalling device. The timer cannot be used for both operations at the same time. 

2.  

Can the DWA-S be configured to synchronize with analog or digital wall clocks?

The DWA-S Sonachron Program Timer is designed to operate as either an on/off controller or a signalling device. The timer cannot be used to synchronize time on other devices. The DWA-S Sonachron Program Timer comes equipped with an RS485 receiver which can be used to receive the time and date from other equipment.

3.  

Does the DWA-S communicate with the Lathem Masterlink software?

The DWA-S Sonachron Program Timer is a standalone unit with the optional capability of getting it's time from another hardware time source. The DWA-S does not have the ability to communicate through any Lathem software products.

4.  

Can the DWA-S be wired to provide a dry contact closure to wire the signalling device to a paging system or tone generator?

Yes. The DWA-S Sonachron Program Timer can provide a dry contact closure to wire the signalling device to a paging system or tone generator. 

5.  

Can the DWA-S be wired to provide a dry contact closure for a paging system or Tone Generator AND be used as an ON/OFF controller or a signalling Device at the same time?

No. If the DWA-S Sonachron Program Timer is being used to provide a dry contact closure to wire the signalling device to a paging system or tone generator, it cannot be connected as an on/off controller or as a bell ringing device. The timer only has one connection circuit.

6.  

Can I program events in less than full minute increments (ie. 15 second time periods)?

No. The DWA-S Sonachron Program Timer can only be programmed in minute increments. Events cannot be programmed in seconds.

7.  

Can I back up the programmed events on the DWA-S in the event that the clock is reset or loses the programming?

The DWA-S Sonachron Program Timer does not have the ability to be backed up electronically. In the event of programming being lost, it must be reprogrammed manually.

8.  

Do I need a step-down transformer if I want to connect a DWA-S to a 24-volt bell or horn?

The DWA-S Sonachron Program Timer has an output of 110 volts or an optional 220 volts. If connecting a 24 volt bell or horn, a Step-down transformer must be connected between the DWA-S and the bell or horn to drop the voltage to 24 volts. Failure to connect a step-down transformer can cause damage to the DWA-S as well as the bell or horn.

9.  

In the event that the DWA-S loses power, is there anyway to recover the programming that was previously set?

The DWA-S Sonachron Program Timer completely loses power, both AC Power and the battery backup, the clock will show 01/01/88 on the display for the date. If this is the case, the programming is irretrievably lost.

10.  

Can the contrast on the DWA-S display be adjusted?

The DWA-S Sonachron Program Timer's display contrast can be adjusted to increase or decrease the darkness of the characters.

11.  

Can the DWA-S be programmed with different signal lengths for different Signal Events?

The DWA-S Sonachron Program Timer's signal length is global for all events. The signal length cannot be programmed differently for different events.
