Shown on this slide are the part numbers for sounds that involve timing. For example, the 10 second delay sound means that when voltage is applied, the alarm will wait 10 seconds and then issue a continuous tone. The 1 minute on-time sound means that when voltage is applied, the alarm will issue a continuous sound for one minute and then shut off until voltage is removed and re-applied. The fast speed-up sound means that over a thirty second period, the sound will speed up from beeping 1 time every two seconds to 8 beeps per second.
