Potter 2020001 BSC Break Safe Contacts Owner's manual

  • I've reviewed the datasheet for the Potter BSC Break Safe Contact. This document details the device's specifications, including its tamper-proof design, contact materials (silver and gold-treated copper), and mounting instructions. The device is designed for safe installations, and I'm ready to answer your questions.
  • What are the contact materials used in the BSC?
    How does the tamper function work?
    What are the environmental limitations for the BSC?
Stock No. 2020001
The Model BSC Break Safe Contact is exterior mounted,
tamper proof and operates with open, closed or double
circuit.
The Model BSC can be mounted in several positions,
depending on the style of safe, by simply loosening the set
screws in the plunger assembly (See Figures 1 and 2).
Insure set screws are tightly secured after repositioning
plunger assembly.
The base is mounted on the safe body and the plunger is
mounted on the door (See Figure 3). The wire entrance to
the base is threaded to accept a 1/2" conduit fitting.
See EVD Bulletin for complete safe protection.

For a normally closed circuit that opens on alarm:
Connect EOL resistor from burglar panel across N.O. and common (top and center) contacts.
Connect N.O. (top) contact to the N.O. relay contact of the EVD.
Connect N.C. (bottom) contact to the common relay contact of the EVD.
Connect zone of burglar panel to the N.O. and N.C. relay contacts of the EVD. (See Fig. 5)
FIG. 5
When installing the BSC in an EVD-C pickup loop:
Wire normally closed only!
If the BSC is installed in an EVD-C pickup loop, it must be wired in series, before the last EVD-P on the loop.
The wire from terminal #4 of the EVD-C goes to the common (center) contact of the BSC.
The normally closed (bottom) contact would go to terminal #2 of the EVD-P.
The shield from terminal #3 of the EVD would connect to the normally open (top) contact, then continue to terminal #1
of the EVD-P.
If it is wired directly to the relay contacts on any EVD:
For a normally open circuit that shorts on alarm:
Connect EOL resistor from burglar panel across N.O. and N.C. (top and bottom) contacts.
Connect N.O. (top) contact to the N.O. relay contact of the EVD.
Connect common (center) to the N.C. relay contact of the EVD.
Connect zone of burglar panel to the common and N.O. relay contacts of the EVD. (See Fig. 4)
