The OEM transceiver modules are compatible with GE Security 
wireless transmitters. The modules have an onboard receiver, 
microprocessor, and connection for a daughter board. The micro-
processor controls the receiver, providing antenna switching and 
AGC functions. It also analyzes the received data from the 
receiver, validates incoming packets, and returns packets to the 
receiver when polled. A daughter board, which communicates 
with the module via an 8-pin header, can be added to implement 
a variety of functions.
Each module encapsulates the receiver functions and formats and 
presents a common interface to the daughter board. Therefore, 
even though protocols vary among the GE Security radio 
frequencies used around the world, the interface is the same to 
the daughter board.

Observe the following guidelines when installing the OEM trans-
ceiver module:

• Allow at least 9 inches (22.9 cm) of clearance above the 

enclosure for the antennas.

• Avoid mounting locations that expose the module to mois-

ture.

• Avoid areas with excessive metal or electrical wiring 

including furnace and utility rooms. If unavoidable, mount 
on or near metal with the antenna extending above the 
metallic surfaces as shown in Figure 1.

For UL installations this module must be mounted in the 600-
1029 enclosure. Daughter boards have not been investigated 
for use by UL.

To mount the OEM transceiver module onto the back plate of the 
600-1029 enclosure, do the following:
1.

Insert the antennas into the antenna shrouds (Figure 2).

2.

Gently slide the top of the circuit board under the two top 
latches.

3.

Snap the circuit board in at the bottom latch to secure it in 
place as shown in Figure 2.

4.

Connect DC power to the OEM transceiver module using 2 
mm power jacks (center positive) or connect flyleads to the 
terminal block as labeled on the board.

For model 600-1025-02-43, the cable length must be less than 
3 m (9.8 ft.) for CE compliance.

Table 1 shows the LED indications for the OEM transceiver 
module.

The following table gives troubleshooting suggestions for the 
OEM transceiver module.

You must be free of static electricity before 
handling circuit boards. Wear a grounding strap 
or touch a bare metal surface to discharge static 
electricity.
