RF Transmitters and Zone States
With the exception of the door/window transmitter, all RF transmitters show only two electrical zone states (Normal and
Faulted).
The RF3401E Door/Window Transmitter can monitor both a reed switch (magnet) and a supervised
sensor loop. After the door/window transmitter's ID is added, the control panel shows one of the
following status messages depending on how the door/window transmitter is configured:
-
-
-
-
The RF3405E Inertia Transmitter operates similarly as the RF3401E described above, however the
RF3405E can monitor both a reed switch (magnet) and a supervised sensor loop or a reed switch and an
inertia sensor loop. It cannot monitor a supervised sensor loop and an inertia sensor loop.
For this example, the door/window transmitter is mounted on a doorjamb and its magnet on the door. Closing the door places
the magnet next to the reed switch. Now the control panel has seen the reed switch in a normal (not faulted) state. From this
point forward, it will show the zone (door/window transmitter) as shorted (faulted) whenever it sees the reed switch faulted. It
will show the zone as normal when the reed switch returns to normal, even though the sensor loop remains faulted.
To continue with this example, we have attached a contact on a window near the door. We have wired in the contact and the
EOL resistor to the Door/Window transmitter's sensor loop and closed the window. Now the control panel has seen the sensor
loop in a normal (not faulted) state. From this point forward, it will show the zone (door window transmitter) as faulted
whenever it sees either the sensor loop or the reed switch faulted. It will only show the zone as normal when both the reed
switch and the sensor loop return to normal. When only the reed switch is monitored, only the Normal and Shorted (Faulted)
zone states are shown.
Cut out reed switch if not used.
Disabling a Zone (Wired or RF)
To disable a wired or wireless (RF) zone, do any of the following:
• Set the location's device parameter to 0 (zero). See Location ##, Device on page 74.
• Set the location's zone function parameter to 0 (zero). See Location ##, Zone Function on page 76.
• Set the location's area parameter to 0 (zero). See Location ##, Area on page 79.
DS7200V2-UK Installer's Guide
"No magnet, no loop": the reed switch is open (no magnet is present), and there is no device
connected to the sensor loop
"Reed switch closed": the reed switch is closed by a magnet
"Loop closed": a device is connected to the sensor loop
"Reed closed, loop closed": the reed switch is closed by a magnet, and a device is connected to
the sensor loop
