Note: When wiring FSL zones, link out the
anti-tamper terminals of each zone in use
on the main connnector and expander
cards.
Figure 4. Wiring Diagram for Single Alarm Contacts and Tamper Wiring
With the loop in a normal state and the alarm contacts closed (shorting out
the 4K7 resistor), the total resistance of the loop is 2K2 ohms. When the
alarm loop is opened and the short removed from the 4K7 resistor, the
resistor is brought into the circuit and the resistance of the loop is increased
to 6K9 causing the end station to detect an alarm condition. If a tamper
device is opened, the loop resistance will be open circuit and the end station
will detect a tamper signal.
The wiring resistance should be restricted to a maximum of 100 ohms. The
recommended maximum cable distance per zone is 200 - 300 metres.
Programming
Initial Power Up
Note: Depending on the status of the system when it is powered-up, e.g., open
tampers etc., some screens may differ from those shown below.
1. Apply battery power first, then connect the mains.
The keypad display shows the Software version number followed by the
date.
After 3 seconds, the display shows the time: 16:07
2. Key in the factory default user code (1234) and press Enter.
The display shows one of the following messages depending on how
the system is currently set up:
SYS DIS RST REQ
3. Key-in the factory default installer code zero (0) + 7890,
then press Menu.
The display shows: MENU NO OR LEVEL
