Testing

You can switch the 4604-55 on so that it transmits a continuous test signal.

This facility helps in range-testing and fault-finding. To activate the test signal

turn the switch marked TEST (on the 2-way DIL switch) to ON.

Figure 12. ON/OFF and Test Switches

To ensure good reception use the Scantronic 4690 field strength meter to

obtain accurate field strength readings and audible and visual indication of

the transmitter’s performance and any interference present.

Turn the TEST switch OFF when you have completed testing, or the trans-

mitter will block ALL radio signals to your receiver!

Final Commissioning

When you are satisfied with the position and channel transmission character-

istics replace the lid. Insert the lid into the bottom of the base. Slowly push

the lid in until it locks into the retaining clip. CAUTION Take care not to bend

or disturb the wire aerial.

Refit the screw and tighten firmly into the base. The red LED lights and the

transmitter sends a closed tamper signal.

Note: DIL switch changes will not take effect until the transmitter is operated twice.

4605

Introduction

The 4605-55 dual function transmitter can be used as a personal attack

transmitter/remote setting device for a 4600 alarm panel, or as a 2-channel

transmitter with the 4612 or 4618/9 receivers and 4660/75 consoles.

To use the 4605 as personal attack button press the two orange side buttons

together. The transmitter does not signal if you press only one button. Note:

the black button fitted below the left-hand orange button. This is a safety lock

to prevent false activations. Slide the black button upwards to lock the orange

button.
