Once the first alarm is received, the alarm LED is turned on steady, this indicates
"PARTIAL ALARM" condition.
The detector is then reset (by removing it's power for 0.5 seconds) and a timer is also
started for 60 seconds (TIMER#1). Another timer of 15 seconds (TIMER#2) is also started.
The zone must alarm again within this 15 seconds (TIMER#2) to register another alarm.
Failure to receive another alarm within this 15 second period will return the zone back to its
normal state immediately and extinguish the alarm LED.
If an alarm is received, the detector is reset again and TIMER#2 is also reset.
This monitoring continues until the 60 second timer (TIMER#1) has elapsed and then the
zone goes into "FULL ALARM". This is the stage at which all relays, bells etc. will operate.
When "FULL ALARM" condition is reached, a third timer (TIMER#3) of 70 seconds is
started. TIMER#2 is kept operating and alarm signals are still to be received as per
previous. Alarm signals are required continually to keep the zone in "FULL ALARM".
Failure to comply with TIMER#2 will result in the zone being returned back to it's NORMAL
state as follows;
If TIMER#3 has elapsed, the zone can be returned immediately back to the normal
state (& de-energise relays if required).
However, if TIMER#3 has not elapsed, the zone cannot return back to the normal
state until TIMER#3 does elapse. Relays etc. will remain energised until TIMER#3 does
elapse.
