Setting Up The Transmitter; Specifications - GE DD205RF/60-947-8A Series Installation Instructions Manual

monitoring the walk test LED on the unit and/or the received
alarms on the panel.
Important:
- The walk test mode can be started once the start-
up sequence has completely finished (LED flashes
for 30 seconds).
- Once the unit is replaced onto the mounting plate,
there is a 10 second interval before the walk test
actually starts. This allows the detector to stabilise.
- Take a 5 second pause between walk tests to
stabilise the detector.
- The walk test mode is only available for 2 minutes.
After that time the walk test LED will no longer
signal generated alarms. If not all walk tests have
been completed within these 2 minutes, repeat step
1 and 2 to re-enter the walk test mode.
- After the walk test mode times out, the detector
returns to normal operating mode. In normal
operating mode, the DD205RF/60-947-8A will only
signal alarms via the wireless link every 3 or 10
minutes (depending on the DIP switch setting) and
the LED is disabled to reduce battery consumption.
Selecting the coverage pattern
The coverage pattern can be changed to fit specific requirements
by using the mirror stickers (enclosed). It is recommended to
blind unused curtains that are looking at walls or windows
located very close to the detector.
Window mask (fig.
A window mask is provided. Fit it to the inside of the detector
window in order to mask objects that are close to (within 1.5
m) or directly under the detector. This disables the part of the
curtains looking at an object whose closeness might otherwise
cause a false alarm. Remove this mask to detect undercrawl.

Setting up the transmitter

The DD205RF contains a built-in transmitter that is used in
conjunction with a compatible receiver. To set up the transmitter
for wireless operation, create a tamper alarm by removing the
unit from the mounting plate (Figs.
Maintaining the detector
When installed and used properly, the DD205RF/60-947-8A will
provide years of service with minimal maintenance. You should
walk test the detector annually as described in Walk testing the
detector to ensure proper operation.
1. Clean the inside of the detector with a soft bristled brush or
compressed air.
2. Clean the cover with a damp (water) cloth as needed to keep
it free of dust and dirt .
Note: Always test the detector after cleaning.
Replacing the batteries
When the system indicates that the detector batteries are low,
replace the batteries as soon as possible.
1. Remove the unit from the mounting plate (Fig. 8A).
2. Pull the ribbon in the battery compartment of the base to
remove the batteries (Fig.
3. Place the ribbon underneath the batteries to facilitate battery
replacement.
4. Observing the polarity markings that are engraved inside the
battery compartment , insert each battery into the battery
compartment of the base (Fig.
lmportant: Once the battery is installed, the DD205RF/60-
947-8A requires 3 minutes to initialise before it will operate.
5. Walk test the detector to ensure correct operation and
coverage. See "Walk testing the detector".
6. If the control panel indicates "Low battery", measure the
battery voltage. If any battery is less than 3 VDC, replace the

battery and repeat steps 1 and 5.
Important: You must remove all the batteries to reset the
low battery signal before installing a new battery.
To prevent a low battery condition, you must install the
battery exactly as described in the "Installing the batteries"
instructions.
Caution:
Batteries can explode or cause burns when recharged,
incorrectly (dis)assembled, or exposed to fire or high
temperatures.
Replace the batteries with: Duracell DL123A or equivalent.
Dispose of used batteries promptly and according to local
regulations. Keep away from children.
Do not insert any batteries in the battery compartment of
the RF transmitter board.
