Sensitivity to 1 Sq. Ft. Gasoline Pan Fire
1.5 Configuration Settings
The SS4-A/-A2 Detector may be reconfigured in the field and thus optimized
for special applications. The configuration of the Detector is set using DIP
switches located on the middle circuit board of the Detector Module. The DIP
switch settings for each configuration are listed in Table 2.
These configurable options include:
1. Fire Verify Relay - The Verify Relay may be disabled or enabled with
several Verify Time settings. It also may be set to act as another Fire
Relay. The Verify Time may be set from 5 to 30 seconds in 5
seconds increments. The Factory setting: Verify Relay Disabled.
When the Verify Relay is enabled and Verify Time is set the Verify
Relay will energize and the Fire Relay will de-energize if the fire
conditions are still present at the end of the Verify Time period. In
the opposite case, the Detector will wait for 5 seconds plus another
Verify Time period to test for the fire conditions. This wait and verify
cycle will repeat 10 times, or until the presence of the fire is
confirmed. This concludes the verification process. If the presence
of the fire is not established the Fire Relay will remain energized
unless Non-Latching mode is set. In case a subsequent fire is
detected the entire verification process will be repeated. The state of
the Fire and Verify Relay after the verification process will depend on
the choice between Latching and Non-Latching modes.
NOTE: When the Verify Relay is enabled and Verify Time is set,
the Fire Relay will de-energize when the Verify Relay is energized.
2. Latching / Non-Latching - The Fire Relay and Verify Relay may be
set in a Latching or Non-Latching mode. The Factory setting for the
SS4-A is Latching and the SS4-A-2 is Non-Latching.
