I. Overview
The 956E Intelligent Input/Output Module(956E module for short) is used with MN300,atwo-bus linkage fire alarm control panel. It is mainly used to realize anoutput control for fire linkage equipment (such as smoke dampers, blow valvesand fire dampers) and receive the feedback signals of the fire linkageequipment so that a judgment on whether or not the fire linkage equipment isoperating normally can be done.
II.Features and technical parameters
1. Mode of operation: Nonpolar two-wire system
2. Quiescent current: ＜0.6mA(power-down mode)
3. Action current: ＜10mA
4. Capacity of the output control contact: 2A@DC30V
5. Operation indicator: The inspection indicatorwill blink once about every 12 seconds in the inspection status or remain litin the output status; the input indicator will remain lit in the feedbackstatus.
6. Operatingenvironment: Temperature: －10℃～50℃; relativehumidity: ≤95% (40℃±2℃, withoutcondensation)
7. Terminal load: 47K resistance
8. External dimensions: 86×86×40(mm)
9. Weight: about 130g
10. Executive standard: GB16806-2006
III.Instructions for use
