BEFORE INSTALLING
This information is included as a quick reference installa-
tion guide. Refer to the appropriate control panel installa-
tion 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
Control Module, Model EM-1SRI, is used to switch an ex-
ternal power supply or audio amplifier to notification ap-
pliances. In addition to switching the external power, the
device will monitor the wiring (while external power is
not switched to the auxiliary devices) to the auxiliary de-
vice for open and short circuits via an end of line resistor.
This module is capable of Class A or Class B operation.
The module also has on-board short circuit isolators to pre-
vent shorts on the signaling line circuit from disabling more
than one device on the intelligent loop.
The control module will also have the capability to moni-
tor the external power input for loss of power (DC volt-
age supplies only). This feature can be disabled through
device configuration programming. If the external power
is switched to the auxiliary devices and there is a loss of
the DC supply, the control module has the capability of
running an algorithm in which the device will switch back
to monitor mode and check the line for short circuits. If

COMPATIBILITY REQUIREMENTS
To ensure proper operation, this module shall be connected
to a listed compatible control panel.
MOUNTING
The module mounts directly to 4˝ square electrical boxes.
The box must have a minimum depth of 2
must be mounted with the arrow facing upward for proper
operation of the IR configuration tool (model no. EA-CT).
Surface mounted electrical boxes (SMB500) are available
from System Sensor.
WIRING
NOTE: All wiring must conform to applicable local codes,
ordinances, and regulations.
1. Install module wiring in accordance with the job draw-
3. Set the address on the module per job drawings using
4. Secure module to electrical box (supplied by installer).

ings and appropriate wiring diagrams. Optional EA-CB
may be required to separate power limited and non
power limited wiring in the electrical box (see Figure
1B). 2. For new installations use the enclosed 39
kΩ EOL resistor. For retrofit applications where the ex-
isting 47 kΩ cannot be easily replaced, it may be left in
place without loss of performance.
