• Low power consumption. The T+, T-alarm bus and the DC24V power bus are non-polar designs and can be regarded as the same fire detector connecting to the alarm buswhich is convenient for construction and flexible in use.
• It can be used as the linkage control execution component of the controller and the controlled device, and can also receive the feedback signal of the controlled device after the action.
• The relay outputs two pairs of normally open and normally closed changeover contacts, among which the K1 and K2 normally open contacts have the function of open circuit and short circuit fault monitoring of the external load.

External terminal arrangement and description for RM5Ei Input/output module

Wiring instructions:
T+, T-: Alarm Bus (with polarity)
24V+, 24V-: 24VDC power supply (with polarity)
X1, X2: Passive Signal Input (Terminal resistance 4.7K)
K1, K2: Normally open contact with external line fault monitoring function, K1
Connect the positive pole of load power, K2 connects the load
K2, K3: Normally closed contacts
NK1, NK2: normally open contacts
NK2, NK3: Normally closed contacts
Note: Inserting the short circuit JP1, JP2, JP3 when coding, it should be unplugged during normal use.
