Retard Adjustment
The retard time is selected by turning the appropriate switches to the off
position.
Example: For 45 seconds turn switches 1, 2 and 3 to the off position.
Approximate time is as follows:
| Switch Off | Time in Sec |
|---|---|
| 1 thru 8 On | 0 |
| 1 | 15 |
| 1 & 2 | 30 |
| 1, 2, & 3 | 45 |
| 1, 2, 3, & 4 | 60 |
| 1, 2, 3, 4, & 5 | 75 |
| 1, 2, 3, 4, 5, & 6 | 90 |
| 7 | not used |
| 8 | not used |

CAUTION
When supervised circuits are used the following must be observed: An uninsulated section of a single conductor should not be looped around the terminal and serve as two separate connections. The wire must be severed, thereby providing supervision of the connection in the event that the wire becomes dislodged from under the terminal.
Application Warning!
Due to the possibility of unintended discharges caused by pressure surges,
trapped air, or short retard times, waterfl ow switches that are monitoring
wet pipe sprinkler systems should not be used as the sole initiating device to
discharge AFFF, deluge, or chemical suppression systems.
Testing: The operation of the waterflow switch and the associated alarms
is to be tested upon completion of the installation and periodically
thereafter in accordance with the applicable NFPA standards and/or the
authority having jurisdiction (manufacturer recommends quarterly or more
frequently).
A minimum flow of 3 GPM (11,4 LPM) is required to activate this device
