Watchgas Detection Beacon Sounder User Manual

watchgas detection Beacon Sounder

DESCRIPTION
The Beacon sounder has 38 Ultra Bright, RGB LEDs with 360° visibility and Piëzo sounder,106 dB at 30 cm. The visual and audible modes can be used independently or combined in any required combination by analog or digital trigger.

IMPORTANT: This user manual contains important information regarding the operation of the beacon sounder. Ensure you read this user manual fully before installing and operating the beacon sounder. If you are installing this beacon sounder for use by others, you must leave this manual with the end user. Installation must be carried out, in accordance with latest codes and regulations, by a qualified electrician.

WARNING

• Ensure power source is disconnected prior to installation or maintenance to avoid damage to the beacon sounder or electric shock.
• Do not handle internal electronical components whilst wiring up. Environmental exposure during installation should be under dry circumstances, avoid heavy moist and wet conditions. The beacon sounder is only weatherproof to IP65 when mounted upright.
• Use M4 screws, washers and nuts (4 pieces supplied) to secure beacon to its mounting.
  Do not mount the beacon sounder on places with excessive vibrations.
• Do not use solvents or cleaners on the beacon sounder, as they may cause damage to the beacon lens or circuitry. The unit can be wiped with a slightly damp cloth.

DISPOSAL
The beacon sounder should not be disposed with your other household waste. The beacon sounder is ideally suited for disposal within the waste electronic and electrical equipment (WEEE) recycling scheme. Check at your local authority, retailer or contact our technical support team for recycling/disposal advice as regional variations apply. You may return the unit to us for safe dismantling and disposal.

GENERAL SPECIFICATIONS

SERIAL PROTOCOL SPECIFICATION

Specification rev 1.0

INTRODUCTION
This document describes how to control and connect the Beacon Sounder PN: Air-Beac-010 over a serial interface. This serial interface can be used to select colour, display effect and sound effect. If the serial input is used, the digital I/O inputs are no longer enabled. The document contains source code that can be used as an example of how to send commands to the beacon sounder.

CONNECTIONS WIRING
The beacon sounder can be powered by only one of these options:

1. Use terminal J4 connect 9 – 30VDC (min 10W) to the + and – terminals
2. Use terminal J2 to connect a 5VDC (+/- 0.1V) 2A power supply. This input has no protection against overvoltage or supply reversal. Use at your own risk.

NOTE
Cable length of TX signal may not exceed 500mm wire distance form signal source.

The signal voltage should be 3.3V TTL/CMOS.

CONNECTOR & CRIMP

DIPSWITCH SETTING
Set DIP switch FN 3 to “ON” to configure the beacon sounder to use a serial input.

DIP SWITCH 3 FN
Function

• ON = J2 TTL Communication protocol
• OFF = J4 terminal block input

PROTOCOL
SPECIFICATION FOR COMMUNICATION

FORMAT
The serial commands consist of a 7 byte string with the following layout.

All ASCII Hex values are a single value ranging from 0 to F.

NOTE
This command has to be repeated at least every 15 seconds. If no command has been received for 15 seconds, the beacon sounder will switch off.

The CRC byte is calculated as following: crcByte = toHex ( (Byte[0] + … + Byte[5]) & 0xF );

LIGHT AND SOUND MODES
The following sound and light modes are implemented:

EXAMPLE CODE

The following C code can be used to implement this protocol.

// Range for r,g,b is 0 .. 255.
// Run this function every 5 .. 10 seconds
void set(BSoundMode s, BLightMode m, uint8_t r, uint8_t g, uint8_t b) {
// Transmit new values
char cmd[9];
cmd[0] = ‘X’;
cmd[1] = toHex(m);
cmd[2] = toHex(r >> 4);
cmd[3] = toHex(g >> 4);
cmd[4] = toHex(b >> 4);
cmd[5] = toHex(s);
cmd[6] = toHex( (cmd[0] + cmd[1] + cmd[2] + cmd[3] + cmd[4] + cmd[5]) &
0xF);
cmd[7] = ‘\r’;
cmd[8] = 0;
// Transmit
printf((const char*) cmd);
}
char toHex(uint8_t x) {
if (x < 10)
return ‘0’ + x;
else if (x < 16)
return ‘A’ + x – 10;
else
return ‘?’;
}
enum BSoundMode {BS_OFF = 0, BS_CONTINUOUS_2K7 = 1, BS_LINEAR_2K7_FAST = 2, BS_
LINEAR_2K7_SLOW = 3, BS_SMALLBEEPS = 4};
enum BLightMode { BS_FAST = 0, BS_SLOW = 1, BS_LOOP = 2, BS_ON = 3, BS_TINYFLASH = 4,BS_FULLFLASH = 5};
