- To put an RF-SABB on to a SecureWave system go into engineer mode.
- Open the RF-SABB and plug in the battery pack to power it up.
- If you have a second device you can open it too at this stage and plug-in its battery pack.
- Don't close their lids just yet.
- Select the Devices Menu, then RF Devs Menu. Next select the Add & Id RF Devs option.
- Next, add and identify the device(s) as RF-SABB.
The sub-menu offers four device types:

Arrow leads to second column: 1 Add&Id:RF Zones / 2 Add&Id:RF Keyfob / 3 Add&Id:RF Echo / 4 Add&Id:RF SABB (highlighted). Arrow from 4 Add&Id:RF SABB leads to Scanning RF Devs in the third column.
1 Add&Id:RF Zones— add and identify RF zone devices2 Add&Id:RF Keyfob— add and identify RF Keyfobs3 Add&Id:RF Echo— add and identify RF Echo sounders4 Add&Id:RF SABB— add and identify the RF-SABB
The system displays Devs Found - 000 when it starts scanning and as it finds its first device the display will change to Devs Found - 001. When the system has found all its devices, press PLAY/QUIT.
- Next, close the devices' tamper switches by fitting their lids.
- As you close the devices' tamper switches in sequence, you will hear an audible indication as each device is identified into the system.
The RF-Echo can have a delayed reaction.

The RF-SABB programmable options can be accessed as follows:
Menu navigation: 1 Service Menu → 2 Devices Menu → 1 RF Devices Menu → 4 RF Device Options
Go to the Devices Menu, then RF Devs Menu. Next select the RF Device Options.
From there go to RF SABB Opts and then select the RF-SABB number in question.
Sub-menu path: 4 RF Device Options → 4 RF SABB Opts → Select SABB (SB1, SB2, etc.)
StatLeds (Status LED's)
SB1 StatLeds (Status LED's) are defaulted to OFF to conserve battery energy. However, if you want to have them flash from left to right then select ALT by pressing YES or flash together in which case you select ON by pressing YES again.
| Setting | Description |
|---|---|
| OFF | LEDs disabled (default) |
| ALT | LEDs flash from left to right |
| ON | LEDs flash together |
Siren Vol (Siren Volume)
You can adjust the device's volume. SB1 Siren Vol (Siren Volume) can be set to LOW, MED or HI.
| Setting | Description |
|---|---|
| LOW | Low volume |
| MED | Medium volume |
| HI | High volume (default) |
Mon Sup (Monitored Supervisory)
SB1 Mon Sup (Monitored Supervisory signal) is defaulted to YES. When the device is "lost" for a prolonged period of time, a supervisory alarm is flagged by the panel. This can be turned off by selecting NO.
| Setting | Description |
|---|---|
| Mon Sup YES | Supervisory alarm enabled (default) |
| Mon Sup NO | Supervisory alarm disabled |
We recommend that this feature is left as YES.
Mon Jam (Monitor for Jamming)
SB1 Mon Jam (Monitor for Jamming), when set to YES, will trigger the siren for 15 minutes in the RF-SABB if there is a breakdown in the communications link with the panel and a jamming signal detected at 868MHz.
| Setting | Description |
|---|---|
| Mon Jam NO | Jamming detection disabled (default) |
| Mon Jam YES | Siren triggers for 15 min on jamming detection |
Block
SB1 Block 0 is where you can assign the device to a specific block (anywhere between 0 and 8).
| Setting | Description |
|---|---|
| Block 0 | Assigned to block 0 (default) |
| Block 0–8 | Assignable to any block from 0 to 8 |
Testing the RF-SABB

Tools Menu (highlighted). Arrow to third column: 1 RF Device Status / 2 Open Inputs Menu / 3 Walk Test Menu / 4 Show System Faults / 5 Test O/P + Channel Menu / 6 Test RF Devices (highlighted). Arrow to fourth column: 1 Test RF Echo ? / 2 Test RF SABB ? (highlighted) / 3 Test RF Smoke ? / 4 Test RF Heat ? / 2 Test RF CO ?.
Menu path: 1 Service Menu → 3 Eng. Tools Menu → 6 Test RF Devices → 2 Test RF SABB ?
Go to Test RF Devices (see menu map above) and select Test RF SABB ?. Select the RF-SABB you want to test and press REC/YES to activate and deactivate the siren and strobe.
Be aware that the siren test can be very loud.
Strobe and Siren Test (at the device)
Close-up view of the RF-SABB PCB (green circuit board) showing two test point jumpers. J1 (left) is labelled Strobe Test with + (left) and - (right) polarity markings. J3 (right) is labelled Bell Test. The HKC logo is visible on the board.
Alternatively you can test the RF-SABB's siren and strobe when you are physically at the device.
- To test the strobe, briefly short the two pins of J1 together.
- To test the siren, briefly short the two pins of J3 together.

If StatLeds (shorthand for Status LEDs) are enabled the batteries will need to be replaced every 6 to 8 months. We recommend that if you would like to use this feature that a secondary battery pack is installed (part number: BAT-PKRFSB6V). Alternatively wire 12Vdc to the SABB and remove the battery pack and install a 6V NiMH rechargeable battery pack (part number: BAT-8.4).
