BEFORE INSTALLING
MOUNTING
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.
The module mounts directly to 4˝ square electrical boxes. The box
must have a minimum depth of 21⁄8˝. Modules must be mounted
with the arrow facing upward for proper operation of the IR pro-
gramming tool. Surface mounted electrical boxes (SMB500) are
available from System Sensor.
NOTICE: This manual should be left with the owner/user of
this equipment.
GENERAL DESCRIPTION
LED
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.
