APPENDIX D
Example of connection circuit of FD "Almaz" to the four-wire fire alarm system
(normally open contacts)
Figure D.1
NOTES:
1. FD base pin assignment:
pins 1, 3 - "-" wire connection;
pins 2, 4 - "+" wire connection;
pins 7, 8, 9, 10 - signal wire connection;
2. Pins 7 and 9 connected in parallel, pins 8 and 10 connected in parallel
ATTENTION! Specific connection circuits of FD "Diamond" to the four-wired alarm
system, and the resistors R rates are given in the user manual of the control panel used.
ATTENTION! It is recommended to use the control panel with the grounded "-" of supply
loop.
