2.1 Additional Technical Data

A suitable transformer with an output voltage of 16 volts AC ±10% with a 16VA minimum rating
must be used. A 32 VA transformer is recommended for larger installations.

A 12V sealed lead acid battery with a minimum capacity of 7AH must be used. The back up
period after mains failure will depend on the number of keypads, sensors and peripheral devices
connected to the system.

The panel can supply a total continuous current of 750mA to peripheral devices such as keypads,
remotes, receivers, passives etc.

Connect a 12-volt self-driven siren or piezo siren [not a horn speaker] to the siren output.
2.2 End-of-Line Resistors
(Including Tamper by Zone / Zone Doubling)

All zones must be end-of-line supervised.

Any unused zones must be terminated with a 3K3 resistor. The end of line resistor must be
placed inside or as close to the sensor as possible.

If neither zone doubling nor tamper by zone are required the 3K3 resistor must be used.

For zone doubling or tamper per zone, the 4K7 and 12K end-of-line resistors must be connected
as per Figures 2 and 3.
Figure 2 : Tamper by Zone Connection
Tamper operation is as follows:

If the panel is unarmed and a tamper condition occurs, the siren will not sound but a tamper
condition will be reported.

If the panel is armed and a tamper condition occurs an audible alarm will register and a tamper
condition AND zone violation will be reported.

Panic zones always register panic and tamper conditions.

The colour codes for the 12K and 4K7 resistors are as per in Figure 4.
