SIGA-REL Technical Reference Manual 43
If your application requires use of the Drill switch to test the SIGA-REL, write a
custom rule to accomplish this. See Figure 19 for an example of the rules
required.
Caution: Do not program the Drill switch to test the SIGA-REL.
Figure 19: Optional rules for using the Drill switch
See “System testing” on page 52 for instructions on checking your work and
testing your system.
Programming the SIGA-REL in the QS-CU
Minimum system requirements
• A QS1 with an SLIC card and appropriately sized standby batteries
• A compatible power supply with appropriately sized standby batteries to
supply 24 VDC to the SIGA-REL
• The SIGA-REL, mounted in an MFC-A enclosure
• A SIGA-CT1 module to supervise the service disconnect switch
• A SIGA-CT2 module to indicate activation of the prerelease and release
relays
When you use monitor or supervisory event messages to indicate activation of
the service disconnect station, prerelease relay, or release relay, you must route
those messages to the panel.
Note: You cannot have more than 10 SIGA-RELs on one SLIC loop.
Step 1: Read this first
WARNING: This information was prepared for users who are proficient in every
aspect of QS-CU programming. Do not attempt to program the SIGA-REL
without a complete understanding of QS-CU and SIGA-REL operation. Incorrect
programming may result in loss of life, serious injury, or property damage.
