The MCP820 Addressable Manual Call Point is suitable for flush mounting indoor applications. A surface mounting back box (SU0632) is available separately. The MCP820 (514.800.611) is designed to monitor and signal the condition of a switch contact that is operated by breaking a plastic coated glass frangible element (515.001.025) (flexible plastic option available 515.001.127). Any change in the status of the switch is immediately communicated to the Tyco MX Control and Indicating Equipment (CIE).
The MCP820 has an integral short-circuit isolator for monitoring the addressable loop wiring. The integral LED indicator is normally off. When the frangible element is broken, an alarm is registered and the LED will illuminate red. If a section of the loop wiring adjacent to the MCP820 is shorted, the built-in shortcircuit isolator trips, isolating the shorted section and the LED is illuminated yellow. The status remains until the short is removed.
