SIR 321
RF Countdown Timer
Part Number BGX501-867-R06
Installation and User Instructions
SIR 321
SIR 321 is a Z-Wave Plus(TM)certified countdown timer that can be used to control immersion heater elements or other electrical appliances rated up to 3 kW.
SIR 321 uses Z-Wave(TM) radio frequency technology to communicate with network controllers from Secure or other manufacturers. It is a mains-powered device that can also act as a network repeater.
INSTALLATION AND CONNECTION SHOULD ONLY BE CARRIED OUT BY BYA SUITABLY QUALIFIED PERSON AND IN IN ACCORDANCE WITH THE CURRENT EDITION OF THE IET WIRING REGULATIONS.
WARNING: ISOLATE MAINS SUPPLY BEFORE COMMENCING INSTALLATION AND ENSURE THE UNIT IS
PROPERLY EARTHED.
Note: SIR321 can be operated in any Z-Wave network with other Z-Wave certified devices from other manufacturers. All non-battery-operated nodes with the network will act as repeaters regardless of vendor to increase the reliability of the network.
The LEDs become operational when the unit is powered up.
User Instructions
To operate the unit press the BOOST button repeatedly until the indicator light for the required BOOST period is illuminated (see table below).

| SIR 321 | 30min V2 hour) | 60min (1 hour) | 120min (2 hours) | off |
When BOOST is active the indicator lights count down, showing the duration of the BOOST period remaining (see table below).

Model |
LED -1 on | LED-1 & 2 on |
LED-1, 2 & 3 on |
| SIR 321 | Smin to3Omin left | 31min to 60min left | 61min to 120min left |
LED -1 will flash slowly when 5 minutes of the boost period remains and will flash at a faster rate when 1 minute remains. At the end of the boost period, SIR will automatically switch to other connected appliances.
SIR 321 can also run a timer from 1 minute to 24 hours, under Z-Wave control. The RF LED shows network and joining status (see STEP-5 for details).
The appliance can be switched oz by canceling the boost period, using any of the following methods:
- If the BOOST button has just been pressed, wait for three seconds and then press it again. The indicator lights should all turn OFF.
- Press the BOOST button repeatedly, until ALL the indicator lights have turned OFF.
- Press and hold in the BOOST button until ALL the indicator lights have turned OFF.
Installation
A means of disconnection from the supply, having at least 3mm contact separation in both poles, must be incorporated in the fixed wiring. We recommend a separate fused circuit from the consumer unit (24-hour supply) protected by a 15A HRC fuse or, preferably a 16A MCB. In some cases, immersion heater failure can damage the SIR. Installation of a 100mA RCD will provide additional protection for the unit. If the SIR is to be connected to a ring main then the spur feeding the controller should be protected in the same way. The SIR is NOT suitable for mounting on an unearthed metal surface.
THE SIR UNIT SHOULD BE KEPT IN ITS SEALED PACK UNTIL ALL DUST AND DEBRIS HAVE BEEN LEARNED AWAY PRIOR TO MAKING CONNECTIONS.
STEP-1 Unpack unit and remove the front cover
Take the SIR out of its packaging and then remove the front cover gently, using a slotted screwdriver in the notch, as shown in the picture below:
STEP-2 Preparing SIR for surface wall mounting
SIR is suitable for mounting directly onto any surface mounted single-gang molded box having a minimum depth of 25mm for the UK or 35mm for Continental Europe. Cable entry can be made through the most convenient cut-out.
Remove cut-outs before fixing the box. Where appropriate, drill the box to provide close-fitting entry for cables and heat-resistant flexible cords. Take care to remove sharp edges.
Ensure that the clamp is positioned the right way up i.e. the projections on the underside of the clamp should grip the cord in order to secure the cable firmly. The cable clamp screws must be adequately tightened up to 0.4Nm.
For flush wall mounting
SIR can be mounted directly to any standard flush mounting single-gang wiring box with a
depth of 25mm for the UK(BS 4662), or 35mm for Continental Europe (DIN 49073). See pictures of gang boxes on page 23.
Clamp all surface wiring to the wall adjacent to the SIR, using trunking where appropriate. The flexible cable to the appliance should be passed through the cable entry hole in the bottom edge of the SIR and secured under the cable clamp provided.
STEP-3 Making connections
Use a twin-and-earth cable with a maximum conductor size of2.5mm2 single conductor for the incoming supply to the SIR. Use a suitably rated three-core flexible cable to connect the SIR to the appliance to be switched. For appliances rated up to 2kW use a minimum of 1.0mm2 flexible conductors. For appliances rated up to 3kW use a minimum of 1.5mm2 flexible conductors. The heat-resistant flexible cable must be used if connecting the SIR to an immersion heater.
| Lin | Live in |
| N in | Neutral in |
| 0 | Supply earth terminal |
| L out | Live out to an appliance |
| N out | Neutral out to an appliance |
| Appliance earth terminal |
All un-insulated earth conductors must be sleeved and connected to the earth terminals on the back of the SIR. The supply earth conductor and appliance earth conductor must use the separate terminal connections provided.
Switch off the mains supply and then connect the conductors for the incoming supply and the appliance on the back of the unit, as shown on the next page . Connect the two leads from the opI”ional external temperature sensor probe (if supplied). The probe wires do not have any polarity.
Note: Temperature sensor-related functionality is active only if the external temperature sensor is connected with the inclusion/exclusion process.
STEP-4 Installing SIR on wall gang/flush wall box
Carefully oXer the SIR to the molded/metal box and secure using two screws. Take care not to damage the insulation or trap the conductors when fitting to flush wall box. 13
STEP-5 Z-Wave commissioning notes
Inclusion steps:
To add the SIR onto a Z-Wave network, first put the controller in Add mod r f3 0 controller installation instructions) and then press sand to hold the pairing button on the unit until the RF LED staRs flash at a fast rate.
Then release the button.
On successful addition, the RF LED will stop flashing.
Exclusion steps:
To remove the SIR from a network put the controller in remove mode (refer to controller instructions) and then follow the sequence for inclusion, as above. After successful removal of the RF LED will flash slowly.
|
Device function |
RF LED status |
| Unit not signed on to the network | RF LED slow flashing |
| RF removal/addition process | RF LED fast flashing |
| RF link lost to the controller | RF LED glow solid |
| RF network status is okay | RF LED off |
For optimum RF communication, fit the unit above floor level, and at least 30cm away. Avoid locations alongside or behind large metal surfaces that could interfere with the low power raéo signals between the unit and the controller.
Factory reset steps:
Press the pairing button and Boost button simultaneously to put the de, vice in a factory default mode, all the configuration, and association set to factory default and removing the device from the Z-Wave network.
Note: Use this proce\lure only when the primary controller is missing or otherwise inoperable. ‘
STEP-6 Fitting front cover and final check
After fitting the mounting screws, fix the front cover back on. OPer the Print cover on fo the unit and make sure that it clicks securely in place.
Fin, ally switch on, the mains supply and check that the SIR switches the appliance on and correctly.
