User Responsibility Amico Microprocessor Based Alarm USER RESPONSIBILITY The information contained in this Installation, Operation and Maintenance Manual pertains only to the Alert-3 microprocessor based digital LCD Alarm. This product will perform as described in this manual when assembled, The information contained in this Installation and Operation Maintenance operated, maintained and in accordancebased with digital the installation instructions provided.
Features • Microprocessor based digital LCD and individual microprocessor on each sensor module • Gas-specific sensors can be mounted locally or remotely, up to 100 feet [30.5 m], utilizing 22 gauge shielded twisted pair (2 shielded wires) • DISS gas-specific sensor housed in a tamper-proof enclosure.
Description of Modules The Alert-3 LCD Alarm is a high technology microprocessor based module: COMMON TO ALL ALARMS SYSTEM POWER SUPPLY The System Power Supply has been pre-installed into the back box assembly. The System Power Supply converts the AC voltage supply to the alarm into two voltages: 5 VDC (regulated) required by the microprocessor hardware and 15 VDC (unregulated) required by the buzzer and the LCD.
Installation Guide STEP 1: THE ALARM BOX Install the back-box to the studs of the wall at the desired height. Ensure that the box is securely in place. The mounting brackets are adjustable to suit the thickness of the wall. MAKE SURE the box is parallel, squared and flush with the finished wall surface to ensure that the frame assembly will fit properly. STEP 2: FOR LOCAL SENSOR ONLY If the sensors are to be mounted locally (inside the back box), the pipe stubs must be connected to the pipeline.
Installation Guide B: REMOTE (outside the back box) Push the sensor module hex-nut and nipple adapter up into the demand checkvalve. With a wrench, tighten the nut so that it makes a good seal. NOTE: Pressure on sensors are not to exceed 250psi for Pressure sensors and 30” for Vacuum sensors REMOTE (Outside the Back Box) 1. Connect a Tee (supplied by others) to the pipeline with a 1/4" NPT female with a 1/4” NPT female connection that will accept A m ii.
all warranty on the alarm. Statements in this manual preceded by the words WARNING, CAUTION, DANGER and NOTE are of special significance. Please read these sections carefully. Installation Guide STEP 6: SYSTEM POWER SUPPLY TURN OFF POWER SWITCH before changing any modules and/or disconnecting any cables. Failure to do soWARNING: can cause the fuse to blow, damaging the circuitry. denotes steps which can prevent injury. i. Ensure that the ON/OFF switch is in the OFF position. ii.
Installation Guide STEP 7: SENSOR MODULE B: LOCAL (inside the back box) i. The sensor module is provided with a 6”-8” [0.1 m - 0.2 m] twisted pair of wires. One wire is red (positive) and the other wire is black (negative). Connect the wires to the display module as shown in Appendix D. Take the red wire from the sensor and attach it to terminal “Sensor +” on the display module. Take the black wire from the sensor and attach it to terminal “Sensor -”.
Installation Guide STEP 9: LCD DISPLAY SETUP i. Press the SETUP button (B1) and press the SELECT button (B4) ii. Volume control: 90, 80, 70, 60 – press CHANGE UP/DOWN to change noise level iii. Press SELECT for LCD brightness and press CHANGE UP/DOWN to change LCD brightness iv. Press the SELECT button (B4) * The following should be displayed.
Programming Gas Locations 1. Use the Notepad program to enter information for gas location. Each line can hold up to a maximum of 16 characters. 2. Two lines may be used per individual gas. 3. The order of the text must go in order of gas; meaning the first two lines of text shall represent the 1st gas location, the next two lines of text shall represent the 2nd gas location, and so forth.

Troubleshooting Symptom An error or “LOW ALARM” LCD screen No power on the alarm Power light is ON, however there is no display on LCD screen No audible alarm Audible signal will not silence Cause Corrective Action The Microprocessor detected a fault and has shut down Turn power switch to OFF position. Wait for at least 5 seconds before turning ON the power. The program will reset itself.
Troubleshooting Symptom Cause Gas reading incorrect Display shows “NO SENSORS” Loose connection of DISS fittings Ensure that the sensor module is properly connected to the DISS demand checkvalve Sensor module is not properly wired to the display module Ensure that the sensor module is properly wired to the LCD module by using wiring diagram in Appendix D or Appendix E Defective sensor or requires calibration Replace the sensor module Defective LCD display module Replace the LCD display module No
