1.0 Responsibilities
Information contained in this Installation and Operation Maintenance Manual pertains to the Ohio Medical Color LCD Touch
Screen Master Alarm (MA) System. The Master Alarm System will operate as described in this manual when operated and
serviced in compliance with the instructions.
1.1 Installer Responsibilities
The alarm should be handled, installed, and tested per the recommended practice as described within this manual.
Should any repair or replacement become necessary, contact Ohio Medical Customer Service (800-448-0770) for original
equipment, replacement parts.
1.2 User Responsibilities
The alarm should be tested and examined periodically according to facility codes. Any parts which are found to be
damaged, corroded, contaminated, etc. should be replaced.
2.0 Alarm System Description & Function
PLEASE NOTE THE FOLLOWING DEFAULT PASSWORD (PW) = “1111”
Note: The unit’s password may be changed anytime. Please contact Ohio Medical Customer Service if your password is forgotten. A Factory
Reset will need to be performed. Upon a Factory Reset, ALL user-customized information/settings will need to be re-entered. Given this,
please store your password in a secure location.
2.1 Description of Basic Alarm & Functions
The alarm is designed to monitor and display the status of up to 30 Alarm Points (APs). When an alarm condition occurs,
a signal is sent to the MA and is displayed on the Liquid Crystal Display (LCD). The unit is capable of relaying alarm
conditions to a Building Management System (BMS) via Dry Contacts, Modbus (or BACnet) or, via Ethernet connection.
Custom alarm labels may be created or chosen in the preprogrammed menu. Examples of alarm conditions include: High/
Low Gas Pressure, Low Vacuum, Manifold Reserve Tank In-Use, High Temperature Shutdown, Reserve Pump Running.
Alarm Events may be viewed/cleared per an individual alarm condition or, collectively as a group. The unit is also
equipped with a Maintenance Mode to permanently silence the audible portion of the alarm until the condition(s) causing
the alarm are xed. Visual Indicators always remain.
Other Key Functions Include:
 Universal 100V-240V AC Power Input with Circuit Breaker Protection
 Normally Open (N.O.) or Normally Closed (N.C.) alarm point set-up
 Alarm Condition Communications (to BMS): Via BACnet, Modbus, Ethernet or Dry Contacts
 Up-To 30 Dry Contact Outputs
 12.1” Full Color LED Screen; Password Protection
 Adjustable Screen-Scroll and Audible Alarm Silence Options

An AP will be displayed in three different ways:
1. Normal Alarm Condition: An AP will display with a green background and white text (as shown below) if
conditions on the source equipment are operating within normal operating parameters.
2. Alarm Condition: An AP in an alarm condition will display with a red background and white text (as shown
below) if conditions on the source equipment are operating outside normal operation.
3. Maintenance Mode: An AP in maintenance mode will display with a yellow background with black text (as
shown below) …. When the AP is manually placed in Maintenance Mode.
Figure 2.2 Below represents a 30 alarm points (APs) set-up. Two APs are in an alarm condition (red), one is in
maintenance mode (yellow) – with the rest seen as operating normally (green).

2.3 Alarm Banners & Silence of Audible Alarm Conditions
The audible alarm will sound under any of the following key conditions:
1. An alarm condition exists for one or more APs.
2. The user adjustable Silence Duration time elapsed and any alarm condition is still present.
3. An alarm input on the MA is congured as Normally Open (N.O.) and the dry contacts for the AP (associated with
the Source Equipment) are congured as Normally Closed (N.C.).
4. An AP is congured, but no actual physical connection to the source equipment is made.
Silencing the Alarm
The Audible Alarm may be silenced in three ways. If the originating cause is not corrected, the following options will not x
the alarm condition.
1. Silencing Button: The audible alarm may be temporarily silenced at any time by pressing
the Master Alarm Silencing Button (right) in the lower right portion of
the screen, regardless of the screen. Each time the alarm is silenced,
the user selected silence duration time will restart.
2. Silencing Duration: The default silencing duration time is 5 minutes. The silence duration can
be user set to a maximum of 59 minutes & 59 seconds. Silencing duration
must be set greater than 0.
3. Maintenance Mode: Any AP can be manually placed into maintenance mode. This will silence the audible alarm.
Visual alarm indicators remain.
2.4 Testing the Alarm Points (APs) [Visual & Audible]
The MAIN MENU screen contains a Test Alarms button. Press and hold the button for approximately ve seconds. The
alarm will sound for 10 seconds along with red and white ashing visual indicators for all Inputs. See Figure 3.C

3.0 Installation
The alarm is shipped fully wired, tested and calibrated. For ease of assembly in walls, the alarm is shipped in two sections;
the Box and Front Panel assemblies. The box is installed in the drywall, then the front panel is attached. Finally, box wiring
and sensor inputs/outputs are congured.

3.3 Installation Instructions Prior to Drywall Plaster
It is important to mount the box between the wall studs at the required height for its intended use. Check all federal, local,
and building codes prior to installation. Adjustable wall-mounted brackets are provided to accommodate for wall thickness
after dry walling, plastering, or other means of wall nishing.
Figure 3.3.1 Remove the metal alarm box assembly from the carton.
Figure 3.3.2 Remove the cardboard dust cover from the metal box via the two screws (X). Re-insert the screws into the
box; they will be used later to hold the cardboard cover in place during drywalling/plastering, and ultimately
used for the front panel hinge assembly.
Figure 3.3.3 Remove the metal wall brackets and hardware from the box located inside the primary box the unit has
shipped in.
Figure 3.3.4 Install the brackets to the left and right sides of the box.
3.3.5 Adjust the brackets so that the front edge of the box assembly
[as shown without the hinged cover] is ush with the nished wall.
3.3.6 Once positioned & square, tighten the hardware securing the
mounting brackets to the alarm box assembly and wall supports.
Do not FULLY tighten hardware at this time.
Keep lightly snug to adjust to wall conditions.

Figure 3.4.5 Take the cardboard dust cover and remove the two sides at the perforations.
Note: If a dust cover is not provided or lost, a piece of cardboard may be cut to cover the alarm box during the drywalling or plastering.
Figure 3.4.6 Gently slide the cardboard in the slits between the inner and outer faces of the alarm box. The two holes
in the cardboard should align with the two holes on the bottom of the alarm box. Assemble the two screws
to complete the process.
Installation Note: The cardboard may also be temporarily taped.

3.7 Master Alarm OUTPUTS
If using dry contacts to connect the APs to a BMS, use the same wiring method/logic as with the INPUTS. It is important
that the wiring for each alarm point OUTPUT correlates to the wiring for the alarm point INPUT. See Figure 3.7 below.
Example: MA 1 INPUT connection corresponds to INPUT P1 on the display. MA 1 OUTPUT connection to the BMS would be wired to the MA 1
Output Terminals.
Corresponds to
INPUT P1
3.7.1 Alarm Outputs via Modbus
For installations that require Alarm Communications via Modbus, the process below should be used in order to
communicate AP information between the Master Alarm and the BMS.
Using communication cable/connector type RJ-11 plug into Serial Port #2 on the HMI/PLC (See Figure 3.7.1). Plug
the other end of the cable into the device that will be monitoring the APs. Reference page 14 for Modbus Net ID screen
conguration.
PORT 2 Master Alarm HMI/PLC Modbus Connection
Use Port 2 for Remote AP Communications. Port 2 is clearly
marked on the unit – please be sure to connect properly.
