Remote Alarm Tests
Global Remote
The Global Remote contacts can be checked for continuity
using a digital multimeter or ohm meter.
•
Normal State (No Alarms)
There should be continuity between the COM and NC
terminals.
The COM – NO circuit should be open.
•
Alarm State
There should be continuity between the COM and NO
terminals.
The COM – NC circuit should be open.
Discrete Contacts
The Discrete Contacts can be tested for continuity using a
digital multimeter with diode check. Since the Discrete
Contacts are open collectors, the diode check function
(
) should be used.
•
Normal State (No Alarms)
All Discrete Contact terminals should be open with
respect to COMMON.
•
Alarm State
There should be continuity between the specific
active alarm terminal and COMMON. Inactive alarms
should remain open with respect to COMMON.
