1.0 INTRODUCTION
The Mircom EC-300 Emergency Call System provides the common features and functions demanded by engineers and
contractors. Over the years, nurse call systems have become increasingly complicated and expensive. Mircom’s EC-
300 system offers a basic system most nurses and administrators feel is necessary.
The EC-300 has been designed for easy operation so few instructions are required for staff to learn and essentially no
training is required.
All “Emergency Calls” are indicated by a fast pulsing audible/visual indication which overrides “Normal” calls of slow
pulsing audible/visual indications. All calls can only be cancelled at the point of activation. The nurse’s station shall
be able to momentarily silence for periods of 10, 5, or 2.5 minutes.
Easy maintenance is obtained on the Mircom system due to its modular construction. All components including the
annunciator panels consists of modular panels for fast servicing and trouble-shooting.
Reliable, solid state construction on the EC-300 system provides trouble-free usage. The audible alarms are solid statet
for long term reliability unlike electro-mechanical devices such as buzzers or chimes. All annunciator lights are long
life, high intensity, wide angle, light emitting diodes (LEDs).
Flexibilityof the system is easy, due to the modular construction. The Emergency Call system and Door Monitoring
can often be combined into the same housing. Blank panels can be provided to be replaced in any future expansion.
System components on a typical system usually include patient stations, emergency stations, corridor lights and
central nurse’s station. This manual will outline each and their various functions.
2.0 INSTALLATION
Before any wiring is done to the system components, check all wires for opens, shorts or grounds, using an ohmmeter.
2.1 PATIENT STATION
The EC-100 or EC-103 Pull Cord Station are normally mounted next to the patient’s bed. All stations have a brushed
stainless finish.
EC-100 Pull Cord Station
The pull cord station is equipped with a 6 foot, white nylon cord easily cut to required lengths. These cords when pulled
operate a switch at the cord station. To reset the patient call, move the switch (at the pull cord station) to the upward
position. Use this station in non-subsequent alarm systems.
EC-103 Pull Cord Station with LED
The pull cord station is equipped with a 6 foot, white nylon cord and a red confirmation LED. The cords when pulled
operate a switch at the station which triggers the LED to illuminate. To reset the patient call, move the switch (at the
pull cord station) to the upward position.
2.2 EMERGENCY STATION
By wiring configuration of the EC-103 Pull Cord Station, the station can be programmed for “Emergency” status calls.
2.3 CORRIDOR LAMPS (DOME LIGHTS)
The Corridor lamps are normally mounted above the doors of all rooms equipped with any type of station. The corridor
lamps have a brushed stainless steel finish with a white plastic wedge shape lens. The lamps mount onto a standard
single gang electrical box. Pressing the lens on top and bottom will unhook the lens from the plate. Replacement
bulbs; use #1820, 24V.

2
EC-104 DOME LIGHT
The EC-104 is equipped with one clear incandescent bulb. The light illuminates whenever the suite station initiates a
call to provide a visual signal in the corridor.
EC-106 DUAL DOME LIGHT
The EC-106 is equipped with two clear incandescent bulbs divided by a barrier strip, top and bottom. The top light
illuminates whenever an Emergency station initiates a call. (Consult our factory, if coloured bulbs are required)
2.4 CENTRAL NURSE’S STATION
The Central Nurses’ Console is normally located within easy reach of operating personnel. The console houses the
centralcontrol and annunciator panels. The console can either be flush or surface mounted. Each console consists
of a backbox, frame, modular annunciator panels and the central call receiver panel.
NOTE: When local bylaws do not allow audible patient calls to be silenced at the console, the ‘disable silence’ jumper
must be cut on the EC-300 Call Receiver Panel.
All console modular panels are made from extruded aluminum and secured to the 300 Series frame by two screws.
The following are the available console panels.
EC-300 CALL RECEIVER PANEL
The EC-300 is the electronic central control board. All wiring is terminated to this panel excluding the selective room
wiring which terminates on the annunciator panels. Connections are made to the EC-300 to determine the type of
system operation and various flash rates. All peripheral devices such as Corridor horns and Duty stations terminate
to the EC-300.
EC-220A ANNUNCIATOR PANEL
The EC-220A has 20 red LEDs to annunciate suite alarms. Each LED has a directory which can be typed with the room
number.
EC-240A ANNUNCIATOR PANEL
The EC-240A has 40 red LEDs to annunciate suite alarms. Each LED has a directory which can be typed with the room
number.
EC-000 BLANK PANEL
Ideal for installations which are built in phases. The EC-000 accommodates one standard panel space which can be
replaced in the future with an annunciator.
TR-074B TRANSFORMER, 24 VAC, 75 VA
The TR-074B is a low voltage transformer used for all the power requirements of the EC-300 system.
2.5 OTHER DEVICES
EC-105A CORRIDOR HORN
The EC-105A is a 24 Volt AC/DC horn to audibly annunciate alarm calls. Made from brushed stainless steel, the EC-
105A mounts onto a standard two gang electrical box.
EC-140 DOME ALARM
The EC-140 mounts onto a single gang electrical box. Made from brushed stainless steel, the Corridor lamp includes
a 24 V DC electronic piezo.

Warranty & Warning Information
Warning Please Read Carefully
Note to End Users: This equipment is subject to terms and conditions of sale as follows:
Note to Installers
This warning contains vital information. As the only individual in contact with system users, it is your responsibility to
bring each item in this warning to the attention of the users of this system. Failure to properly inform system end-
users of the circumstances in which the system might fail may result in over-reliance upon the system. As a result, it
is imperative that you properly inform each customer for whom you install the system of the possible forms of
failure.
System Failures
This system has been carefully designed to be as effective as possible. There are circumstances, such as fire or
other types of emergencies where it may not provide protection. Alarm systems of any type may be compromised
deliberately or may fail to operate as expected for a variety of reasons. Some reasons for system failure include:
•Inadequate Installation
A Fire Alarm system must be installed in accordance with all the applicable codes and standards in order to provide
adequate protection. An inspection and approval of the initial installation, or, after any changes to the system, must
be conducted by the Local Authority Having Jurisdiction. Such inspections ensure installation has been carried out
properly.
•Power Failure
Control units, smoke detectors and many other connected devices require an adequate power supply for proper
operation. If the system or any device connected to the system operates from batteries, it is possible for the
batteries to fail. Even if the batteries have not failed, they must be fully charged, in good condition and installed
correctly. If a device operates only by AC power, any interruption, however brief, will render that device inoperative
while it does not have power. Power interruptions of any length are often accompanied by voltage fluctuations which
may damage electronic equipment such as a fire alarm system. After a power interruption has occurred,
immediately conduct a complete system test to ensure that the system operates as intended.
•Failure of Replaceable Batteries
Systems with wireless transmitters have been designed to provide several years of battery life under normal
conditions. The expected battery life is a function of the device environment, usage and type. Ambient conditions
such as high humidity, high or low temperatures, or large temperature fluctuations may reduce the expected battery
life. While each transmitting device has a low battery monitor which identifies when the batteries need to be
replaced, this monitor may fail to operate as expected. Regular testing and maintenance will keep the system in
good operating condition.
•Compromise of Radio Frequency (Wireless) Devices
Signals may not reach the receiver under all circumstances which could include metal objects placed on or near the
radio path or deliberate jamming or other inadvertent radio signal interference.
•System Users
A user may not be able to operate a panic or emergency switch possibly due to permanent or temporary physical
disability, inability to reach the device in time, or unfamiliarity with the correct operation. It is important that all
system users be trained in the correct operation of the alarm system and that they know how to respond when the
system indicates an alarm.
•Automatic Alarm Initiating Devices
Smoke detectors, heat detectors and other alarm initiating devices that are a part of this system may not properly
detect a fire condition or signal the control panel to alert occupants of a fire condition for a number of reasons, such
11

as: the smoke detectors or heat detector may have been improperly installed or positioned; smoke or heat may not
be able to reach the alarm initiating device, such as when the fire is in a chimney, walls or roofs, or on the other side
of closed doors; and, smoke and heat detectors may not detect smoke or heat from fires on another level of the
residence or building.
•Software
Most Mircom products contain software. With respect to those products, Mircom does not warranty that the
operation of the software will be uninterrupted or error-free or that the software will meet any other standard of
performance, or that the functions or performance of the software will meet the user’s requirements. Mircom shall
not be liable for any delays, breakdowns, interruptions, loss, destruction, alteration or other problems in the use of a
product arising our of, or caused by, the software.
Every fire is different in the amount and rate at which smoke and heat are generated. Smoke detectors cannot
sense all types of fires equally well. Smoke detectors may not provide timely warning of fires caused by
carelessness or safety hazards such as smoking in bed, violent explosions, escaping gas, improper storage of
flammable materials, overloaded electrical circuits, children playing with matches or arson.
Even if the smoke detector or heat detector operates as intended, there may be circumstances when there is
insufficient warning to allow all occupants to escape in time to avoid injury or death.
•Alarm Notification Appliances
Alarm Notification Appliances such as sirens, bells, horns, or strobes may not warn people or waken someone
sleeping if there is an intervening wall or door. If notification appliances are located on a different level of the
residence or premise, then it is less likely that the occupants will be alerted or awakened. Audible notification
appliances may be interfered with by other noise sources such as stereos, radios, televisions, air conditioners or
other appliances, or passing traffic. Audible notification appliances, however loud, may not be heard by a hearing-
impaired person.
•Telephone Lines
If telephone lines are used to transmit alarms, they may be out of service or busy for certain periods of time. Also
the telephone lines may be compromised by such things as criminal tampering, local construction, storms or
earthquakes.
•Insufficient Time
There may be circumstances when the system will operate as intended, yet the occupants will not be protected from
the emergency due to their inability to respond to the warnings in a timely manner. If the system is monitored, the
response may not occur in time enough to protect the occupants or their belongings.
•Component Failure
Although every effort has been made to make this system as reliable as possible, the system may fail to function as
intended due to the failure of a component.
•Inadequate Testing
Most problems that would prevent an alarm system from operating as intended can be discovered by regular testing
and maintenance. The complete system should be tested as required by national standards and the Local Authority
Having Jurisdiction and immediately after a fire, storm, earthquake, accident, or any kind of construction activity
inside or outside the premises. The testing should include all sensing devices, keypads, consoles, alarm indicating
devices and any other operational devices that are part of the system.
•Security and Insurance
Regardless of its capabilities, an alarm system is not a substitute for property or life insurance. An alarm system
also is not a substitute for property owners, renters, or other occupants to act prudently to prevent or minimize the
harmful effects of an emergency situation.
IMPORTANT NOTE: End-users of the system must take care to ensure that the system, batteries, telephone lines,
etc. are tested and examined on a regular basis to ensure the minimization of system failure.
