Figure 3-7 Alarm Silenced message

If Relay 1 has be configured as an ALARM relay it will be turned on when an alarm condition is recognized and will be turned off when all audio indicators have been silenced.

Silencing applies to the cause(s) of the alarm when the HUSH key is pressed.

3.1.5 Warning Status Display

When any sensor indicates a gas level that is at or above the configured warning level for the sensor, the panel will enter WARNING mode during which the internal buzzer will sound, the alarm/warning lamp will be amber and the LCD will show the sensor type and channel number.

The display will cycle through all sensors that are signaling warning levels, at five seconds per display. Pressing any key (except HUSH) will advance the display to the next sensor that is signaling a warning level.

If the buzzer and/or an external horn and/or external strobe are connected and configured to signal a warning condition, they will also sound when a warning condition occurs. There is a configurable delay for the horn or strobe will sound, see sections 3.3.5.3 and 3.3.6.3.

When the HUSH key is pressed, the internal buzzer will be silenced for fifteen (15) minutes. If the horn or strobe turn on delays have not finished then they will also be silence. If the delays have finished, the HUSH key must be held for three (3) seconds in order to silence the horn and strobe.

When all indicators have been silenced, the display will show that warnings have been silenced for fifteen minutes. After any key is pressed (or five seconds) the display will return to normal mode.
