Operation
This chapter describes the operational capabilities of the MR-3318
5.1
Addressable/Analog Devices
The MR-3318 System supports one loop of Advanced Protocol and CLIP compatible devices.
Using the
Advanced Protocol
the MR-3318 supports up to:
•
159 addressable sensors per loop.
•
159 addressable modules per loop.
Using the
CLIP
protocol the MR-3318 supports up to:
•
99 analog sensors per loop.
•
99 analog modules per loop.
Configuration is done via the MSW-042 software configurator.
Additional Information
•
The addressable loop can be configured for Class A or Class B operation.
•
T-tapping is not recommended.
•
Unshielded twisted pair (UTP) is recommended.
•
Conventional devices can be used in a semi addressable application in conjunction with
MRI-M502M, MRI-M502MA, MRI-M502MAP, or MRI-M502MAPA Intelligent
Addressable Interface Modules.
•
A short or open on the loop will activate the common trouble sequence with a latching
trouble. (Class A only)
•
DO NOT connect more than 25 devices to a single isolator or between isolators.
•
The MR-3318 FACP will test the sensitivity of a single sensor address every 4 minutes.
Each address will be tested once in approximately every 11 hours.
