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).

• Flexibility of 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.

2.1.1 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.

2.1.2 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.

2.3.1 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.

2.3.2 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

6

central control and annunciator panels. The console can either be flush or surface mounted.

i

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.

2.4.1 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.

2.4.2 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.

2.4.3 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.

2.4.4 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.

2.4.5 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

2.5.1 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.

2.5.2 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.

Call Back

F1 and F2

2.6.4 Power Consumption Chart

To prevent staff from forgetting a call previously silenced, a time-out call back feature is
available. A selectable DIP switch on the EC-300 Call Receiver board will re-activate the
audible alarm within 2.5, 5 or 10 minutes.

This controls the volume output to the internal/external speaker.

With jumper in, alarm tones can be silenced.

With jumper removed, alarm tones can not be silenced.

Select only one setting at a time; 2.5m, 5m or 10m which represents a call back duration of 2.5 , 5
or 10 minutes respectively. This control will re-activate the alarm tones after the pre-selected time
delay has expired.

Control unit fuses. replace only with maximum 3 amp, 250v type
