End of line terminating resistors must be used for the Arm/Disarm Zones (labelled
“ARM” on the Panel) as well as the four Alarm Zones (labelled “1”, “2”, “3”and “4”on
the panel) even if a zone is unused. Failure to do so will result in the zone showing a
violated state, which will prevent the panel from arming.
Zone Circuits must be wired up as per the “Typical EOL Zone Circuits” shown in
figure 1. It is recommended that a 0.4mm multi-core solid copper alloy cable be
used to wire up the zones.
Tamper Input
The Tamper input is not end of line monitored. It is located to the left of the siren
fuse and is labelled Tamper (reference Fig 1.) A “normally closed” switch or contact
must be connected to this input in order to operate correctly. If unused ensure that
a jumper is placed across the contact. Failure to add a jumper across this output
will prevent the panel from arming. This is indicated via the power LED blinking at a
faster rate of four times in on second versus once per second in a normal state
Siren Output
The Siren output is a normally open contact. It supplies power directly from the
battery through the siren fuse. A siren should be connected as shown in Figure 1.
Any Siren up to 30W in size can be connected to this output. The siren output
sounds Alarm, toot on arm and toot on disarm notifications. An Alarm toot sounds
for 1 minute. Toot on arm is a single beep for 1 second and toot on disarm is a dual
beep of 1 second in length.
Strobe Output
The Strobe is an uncommitted normally open contact. It is triggered by an alarm
condition in the armed state. Once triggered the strobe output will remain triggered
until the alarm panel is disarmed.
