Commissioning Guide and A1536 Application, Installation and Commissioning
Guide.
The panel requires an A1619 interface module fitted to the motherboard to
communicate with I/O boards. Note that if panel repeaters are fitted to the panel two
A1619 interfaces will be required, one for the repeater communication and one for the
I/O connection.
16.11Panel Cause/effect Timers
The panel contains four timers for use in cause/effect programming. These are
configured to operate as panel inputs and outputs. Each timer is started by driving a
panel output; when the timer delay ends a corresponding panel input is operated. The
timer period can be set in 1 second increments between 1 and 32000s (8 hours, 53
minutes and 20 seconds). Each timer is configured using the PC cause/effect editor
and cannot be accessed through the menu.
16.12Class –change Modes
The operation of the class change input, may be selected to operate ouput bit 0
(steady) or 1 (pulsed), of any loop sounder controllers.
17.Power Supply Load Calculation
The power supply load must not exceed a maximum of 4A for Premier AL Panel. To
determine the maximum power supply load perform the following steps:
1. Look-up the mains failed panel load in alarm. Enter this value as I
panel
.
2. Calculate the maximum alarm load on each loop in mA. Enter the sum of the
values as I
loops
.
3. Calculate the maximum load on the alarm circuits in mA in an alarm condition.
Enter this value as I
alarms
.
4. Calculate the load on the auxiliary supply in mA in an alarm condition. Enter this
value as I
aux
.
5. Calculate the maximum power supply load using the formula below:
I
