2 INPUT, 1 OUT MODULE - ESMI EM221EA
The 2 INPUT, 1 OUT MODULE - ESMI EM221EA (FFS06717022) provides dual channel
monitoring of normally open contact and supervisory devices, and also provides single
pole changeover contacts for the control of auxiliary devices such as fire shutters and
sounders.
1.1
Addressable EM200-series I/O-modules
The EM200 series of modules are a family of microprocessor-controlled interface devices
permitting the monitoring and/or control of auxiliary devices and are compatible Esmi
Sense FDP and FX 3NET fire detection system.
Compact construction enables more units to be mounted in installation boxes.
The module has a wide range of input/output combinations. Built in short circuit isolators
save installation costs as separate isolator units are not needed.
The 2 INPUT, 1 OUT MODULE - ESMI EM221EA has a single tri-colour green/red/yellow
LED, which can be set by panel command to pulse green each time the module is polled.
In case of an alarm the panel switch the red indicator on continuously. The Yellow LED is
controlled by the module and blinks to indicate an open circuit on the input circuit. This
fault indication is overridden by a panel command to turn the red LED on.

Address setting
All modules are addressable. The address setting is done with two rotary switches,
accessible either on the wide side or the front edge, depending on means of mounting.
The dual input and dual input – single output modules are automatically assigned to two
and three consecutive addresses.

Installation
EM200 series modules can be mounted in several ways (See below):
These modules must only be connected to Esmi Sense FDP and FX 3NET fire detection
systems equipped with SLC loop controller. Also compatible with Fx LC and Esa/Sesa
LIB loop controllers.
The surface mounting box has a transparent cover that enables verification of address
setting and visibility of LEDs, without cover removal.
1:1 An M200E-SMB custom low profile surface-mounting box. The SMB Base is affixed
to mounting surface, and then the module and cover are screwed onto the base
using the two screws supplied. Box dimensions: 132 mm (H) x 137 mm (W) x 40 mm
(D)
1:2 The DIN bracket on top allows mounting onto standard 35 mm x 7.5 mm "Top Hat"
DIN rail inside a control panel or other suitable enclosure. Push module into adaptor
bracket until it clips into place. Locate top clip over DIN rail and rotate bottom down
to clip into place. To remove, lift up, then rotate top away from the rail.
Wiring to all series EM200 modules is via plug in type terminals capable of supporting
conductors up to 2.5 mm².

Notes!
1. If short circuit isolation is not required, loop output+ should be wired to terminal 5
and not 2. Terminal 5 is internally connected to terminal 4
a: T1 Loop Output -. b: T2 Loop Output +. c: T3 Loop Input -. d: T4 Loop Input +
e: T5 Loop Input +. If short circuit isolation is not required, loop output+ should be wired
to terminal 5 and not 2. Terminal 5 is internally connected to terminal 4.
f: Short circuit monitoring of the input(s) can be done by adding an 18kΩ resistor in series
with each device input switch being monitored.
g: Relay contact rating: 30V DC, 2A resistive load.

Warning: Switching Inductive Loads (EM221EA Output Channel Only)
See above. Inductive loads can cause switching surges, which may damage the module
relay contacts (i).
To protect the relay contacts, connect a suitable Transient Voltage Suppressor (iii) - for
example 1N6284CA - across the load (ii) as shown in illustration above.
Alternatively, for unsupervised DC applications, fit a diode with a reverse breakdown
voltage greater than 10 times the circuit voltage.
