Issue
CMD 4 will not stop the keypad Trouble Tone.
Solution
The point could be programmed as RING UNTIL RESTORED (YES) and or BUZZ ON FAULT is activated.
Ring Til Rst: Parameter Description
Use this option to determine if the bell will continue to ring until the Fire Bell time expires. The point is returned to a normal condition when the user can acknowledge the alarm to silence the bell.
Use this option for fire applications to meet the requirement that audible alarms cannot be silenced until the fault condition clears or the Fire Bell time expires.
IMPORTANT: If the point restores and the fire alarm is not silenced from the command center, the fire alarm output continues until Fire Bell time expires. If the point does not restore, the fire alarm output continues even after bell time expires.
Parameter Options:
- Yes:The relay programmed to provide fire alarm output for this point can not be de-activated until the point restores to normal.
- No:The relay programmed to provide fire alarm output for this point can be de-activated before the point restores to normal.
BUZZ ON FAULT: Parameter Description:
For Point Indexes 6 and 9, the default setting is 1. Use this option to generate a Trouble Buzz even if the point is not actually in trouble. This does not affect normal point trouble (T) buzz. The buzz does not automatically stop once the point is restored when using Selections 1 or 2. The user must acknowledge the buzz prior to the buzz stopping. However, when using Selection 3, the trouble tone will stop when the point restores to normal. If the fault occurred while the system was armed or if it was a 24-hour point and in both cases an alarm occurred, the buzz will follow the silencing of the bell or at the end of the bell time.
Parameter Options:
- Blank:The point will only generate a buzz at the command center if it goes into the trouble condition indicated in the P## Pt Response .
- 1: The point will generate a buzz until restore at the command center for any fault condition while the point is disarmed. The buzz will continue until the point restores and the user acknowledges the condition using a passcode or Command 4. The point must be normal before the user can silence the buzz.
- 2: The point will generate a buzz at the command center for any fault condition while the point is disarmed. The point does not have to be normal before the user can silence the buzz.
- 3: The point will generate a buzz at the command center when the point is off-normal while the area is disarmed. The user cannot silence this buzz (by either passcode or Command 4), but it silences automatically when the point restores.
