4. Replace Alarm Indicator.
If the optical sensor chamber becomes very heavily contaminated, the amber fault
light will flash once every 40 seconds to inform the user. Action can then be taken to
replace the unit, long before the contamination causes nuisance alarms.
5. Alarm Memory.
After a the unit has gone into alarm, the red alarm light will flash twice (1 second apart)
every 40 seconds to indicate that the unit has alarmed in the previous 24 hours.
Additionally, pressing the test button on this unit will cause it to emit short, rapid beeps
instead of the normal alarm sound. Both these features allow easy identification, for
example, of the source of nuisance alarms during the night.
6. Single Person Interconnect Test
Pressing and holding the test button on the unit causes the alarm to sound. On
releasing the test button, the alarm will immediately cease but all interconnected
alarms will continue to sound for 3 seconds. This allows easy audible check of alarm
interconnection.
