BEFORE INSTALLING
This  information  is  included  as  a  quick  reference  installation 
guide. Refer to the appropriate control panel installation manual 
for detailed system information. If the modules will be installed 
in an existing operational system, inform the operator and local 
authority that the system will be temporarily out of service.
NOTICE:  This  manual  should  be  left  with  the  owner/user  of 
this equipment.
GENERAL DESCRIPTION
Relay Module, Model EM-1RI, is to be designed for use in activa-
tion of the types of products that are generally connected to an in-
telligent fire alarm system. It provides two sets of form C contacts 
that switch together (one DPDT relay). There is also an input that 
is capable of monitoring a dry set of contacts for open or closed 
conditions. The module also has on-board short circuit isolators 
to prevent shorts on the signaling line circuit from disabling more 
than one device on the intelligent loop.
COMPATIBILITY REQUIREMENTS
To ensure proper operation, this module shall be connected to a 
listed compatible control panel.
