66 AFP-200 Instruction PN 15511:F2 10/11/99
4.16 Special System Timers
Silence Inhibit Timer (0-300 seconds)
The Silence Inhibit timer starts at the first alarm and restarts with each new alarm. It prevents the Alarm Silence
switch from functioning.
Auto Silence Timer (0=no timer, 600-900 seconds)
If the Auto Silence Timer is selected and times out, it performs the same function as pressing the Alarm Silence
switch. Pressing the Drill switch starts the timer.
Alarm Verification Timer (0-30 seconds)
If a smoke detector (CPX or SDX) is selected for Alarm Verification, its alarm is ignored for the Alarm Verifica-
tion time. If an alarm from another point occurs while timing, it dumps the timer and activates the alarm. If
time-out and alarm still exists, it performs all standard functions. If time-out and alarm no longer exists, the
control panel increments the verification counter for this device (stops at 99) and returns to normal.
Waterflow Circuits Operation
If an alarm exists from a MMX point that has a waterflow type code, the Alarm Silence switch will not function.
Disable/Enable Operation
Input points which are disabled do not cause an alarm or any CBE activity. Disabled output points are held in
the off state. All disabled points are treated as if they were in trouble except the status banner is DISABL.
4.17 Style 6 Operation
If the communication loop is wired and programmed for Style 6 or Style 7, and a single fault occurs, the control
panel will detect the fault and drive both ends of the line, fully recovering from the fault. The control panel
latches the trouble and displays it until System Reset. The LCD display shows STYLE 6 trouble type. Style 7
requires use of the ISO-X isolator modules (refer to Chapter 2).
