D. REMOTE ALARM - RA™

RA Ordered as an accessory, includes 8” harness with

connector, and two (2) wire nuts.

1. DESCRIPTION

This remotely mounted AUDIBLE and VISUAL alarm connects to

any Myron L Company AQUASWITCH II Monitor/controller, or

brand “X” controller with dry contacts. When activated by the

controller the Remote Alarm will provide both an audible and a

visual alert at a location other than at the controller.

A mute button will silence the piezo alarm for up to 10 minutes

while the LED remains illuminated. After the preset time the piezo

alarm will again sound, this will repeat until the water quality is

corrected. Thus allowing servicing of the system under control,

while still acting as a reminder if the problem has not been

corrected.

The Remote Alarm - RA™ is an inexpensive way to alert personnel

of a trouble situation. For example; the Monitor/controller may be

located with an RO system while the service technicians are on

another floor or even in another building - great for hospitals. The

AUDIBLE alarm may be silenced, but stays in alarm (RED LED is

still illuminated) until the trouble is corrected. The timer may be

set from 15 seconds up to 10 minutes, thereby, giving personnel

the time to correct the problem while not being able to ignore the

trouble because of the reoccurring AUDIBLE and VISUAL alerts.

2. INSTALLATION

Briefly —

Only 2 wires to connect from the controller to the RA.

Set the time.

Mount on the wall or on the bench.

CAUTION - READ FOLLOWING CAREFULLY

WARNING: BEFORE STARTING, IF THE

AQUASWITCH IS INSTALLED, ENSURE THE POWER

IS OFF. FAILURE TO DO SO COULD CAUSE DAMAGE

TO THE INSTRUMENT, AND COULD BE HARMFUL OR

FATAL TO PERSONNEL. ONLY QUALIFIED

PERSONNEL SHOULD INSTALL ELECTRICAL

EQUIPMENT.

The Remote Alarm - RA connector is labeled 24 VDC INPUT and

has a 8” 2 conductor wires attached — Black is Positive (+) and

White is Negative (-).

When extending the wires you may use any two color wire you

wish just remember the polarity — Black is Positive (+) and White

is Negative (-). Wire lengths of 500 feet/152 meters have been

tested and have no adverse effect on performance although a

length of 500 feet/152 meters would be unusually long.

Ensure the unit is completely wired, tested and adjusted before

installing RA to mounting surface as the tape will not remove from

mounting surface without damaging the adhesive.

For OEM models skip steps referencing enclosure or front panel.

1. Run #22, 2 conductor speaker type wire, NOT supplied,

from Monitor/controller to RA location as necessary. Wire

may be ordered from the Myron L Company, part #RAW-

200.

2. Open the RA by removing the four screws.

3. Locate and remove the 8” 2 conductor wire with the

reddish brown connector attached to the RA. See figure

III.D.1.

4. At the RA, connect the extension wires to the connector

on the RA circuit board — Black to Positive (+) and White

to Negative (-) as shown in figure III.D.1.

5. Using a standard slot screwdriver remove the two (2)

screws on the Myron L Monitor/controller front panel.

6. Carefully wiggle the front panel to loosen the gasket and

pull gently toward you. Do not pull more than about 8

inches/20CM or you could damage the wiring harness.

7. Connect the extension wires to the 8” 2 conductor wire

with the wire nuts provided — Black to Positive (+) and

White to Negative (-). Be sure to first pass the wire

through the user supplied waterproof strain relief in the

enclosure.

8. Plug the reddish brown connector into the male

connector on the controller circuit board marked RA (see

inside case label or figure III.D.2 for location). It will only

go on the connector one way.

9. To test, simply turn ON the controller and adjust

controller set point until the alarm sounds off*. If

controller is not yet connected to water, on

conductivity/TDS controllers it will be necessary to press

and hold the Full Scale Test Switch. See figure III.D.2.

The black button on the front of the RA will mute the piezo
