<p>PURPOSE:To easily cope with the change of circumstances in an installation place by storing fundamental programs, processing systems, and sensitivities in the storage means of a sensor and connecting only those to be used to a microprocessor. CONSTITUTION:Terminals t1 to t3 of a CPU 10 are connected to high or low voltage terminals by a wiring pattern, and a fundamental program is selected by this connection combination. Terminals t4 to t6 are connected to high or low voltage terminals through the switch part of a processing system designating switch SWA, and a processing system is selected by this connection combination. A sensitivity is selected by the connection combination of terminals t7 to t9. When the fundamental program, the processing system, and the sensitivity in a ROM 12 are selected in this manner, they are linked to an MPU 11 and fire monitor is performed by the program. Thus, the system and the sensitivity are easily set and changed to easily cope with the change of circumstances.</p> |
