StemarShop V-ALARM Stemar Security Systems
Product Information
The V-ALARM module is a vibration detection module. It can be used in standalone mode or connected with an existing security system. It has flexible configuration options and offers itself to various applications.
| Part Number | Description |
|---|---|
| V-ALARM-1-STD | Standard VALARM unit |
| V-ALARM-1-GRM | For use with GALARM system |
APPLICATIONS
- Gate monitoring (including swing gates) to detect gate tamper, gate motor tampering and theft
- Home Security gates
- Solar panel monitoring
- Garage door monitoring
- Caravan and boat monitoring
- Power Distribution Boxes
REQUIREMENTS (Application dependent)
- 10-16V DC input supply
- A NON-Integrated RF receiver with trigger LOW (Ground) when remote is pressed (for remote control applications). Can be used with your current gate motor RF Receiver as long as it is not an onboard or integrated receiver. Or you could use an optional separate receiver. Sherlotronics RX1-150 or similar suggested.
- (Optional) TX transmitter with trigger LOW (Ground) to transmit to alarm (Sherlotronics S1 or similar suggested)
- (Optional) Alarm system (wired NC contact like alarm PIR sensor or beam).
INSTALLATION PROCEDURE
- Wire the PCB as per below instructions.
- Use double-sided tape to stick PCB to inside of enclosure.
- Use double-sided tape to stick PCB to unit to monitor (ie on gatemotor motor or controller, on garage door frame, on security gate frame, underneath solar panel). Use Sikaflex FC11 for more permanent installations in challenging environments.
- Test the VALARM sensitivity. The STATUS LED will flash every 3-4 seconds in standby mode. Once a tamper\vibration is detected, the STATUS LED will stay LIT while vibration is occurring.
- The VALARM is shipped with a default sensitivity setting, which is sufficient for most monitoring applications.
- If required, adjust sensitivity with small screwdriver as required (clockwise for less sensitivity).
- Shake gate or garage door, to ensure device triggers.
- Close lid on VLARM unit, and replace four (4) screws.
FUNCTIONAL DESCRIPTION
Table 1 shows the functional purpose of each connection on the V-ALARM module.
| INPUT/OUTPUT | DESCRIPTION |
|---|---|
| VIN- | Negative input of power supply |
| VIN+ | Positive input of power supply |
| OUTPUT | TRIGGER output, open collector, active LOW |
| RX_IN | Input from RX receiver (active LOW when remote press) |
| RLY_COM | Relay COM connection |
| NO/NC | NO/NC relay connection (Selectable with W1/W2) |
- On power-up, the STATUS_LED will flash two (2) times. The STATUS_LED will then flash ONCE every few seconds, indicating the unit is RUNNING in STANDBY mode.
- The vibration THRESHOLD can be adjusted on the POTENTIOMETER (TRIMMER) during installation. Once the vibration THRESHOLD is exceeded, the STATUS_LED will switch ON, and an alarm condition will trigger. During an alarm condition, the RELAY output will activate.
- The OUTPUT will switch ON (pull to GND) and OFF twice during this time. The STATUS_LED will indicate the alarm condition, as per Table 3.
- Once the SIREN TIME (30 seconds) has expired, the RELAY output will switch OFF. The STATUS_LED will return to the STANDBY condition
- The STATUS_LED will then indicate the unit STATUS following the event, as per Table 2.
- When the input voltage drops below 10V in standby mode, an alarm condition will also trigger. This is to ensure that the voltage is sufficient for typical RF transmitters used to link to alarm system.
- This option can be disabled if required. Contact us for information on disabling this feature.
STATUS LED| DESCRIPTION
---|---
FLASH x1| Running in STANDBY mode
FLASH x2| Vibration Trigger
FLASH x3| Low-voltage trigger
FLASH x4| Gate-open authorized
V-ALARM integration
When the V-ALARM module is used in standalone mode, it can be connected to a
siren, alarm RF transmitter and\or alarm system (through Relay NO/NC
connection).
GATE MONITORING
The RX_IN input can be connected to the gate motor Receiver. When a paired remote is pressed (causing the gate to open when the Receiver pulls LOW (to GND)), the V-ALARM will acknowledge authorized opening of the gate, and NOT TRIGGER an alarm condition. The V-ALARM will ignore any alarm condition for two (2) minutes while the gate open and close. Pressing the paired remote again will restart the two (2) minute counter every time it is pressed.
The RELAY contact can be set to NO (Normally-open) or NC (Normally-closed), by
soldering the W1 (NC) or W2 (NO) link. NOTE only the applicable link should be
soldered. The VALARM module has a cur
rent
consumption of +-1mA in STANDBY mode (no vibration detected). It can be used
in applications where only a battery, such as a 12V 7Ah SLA battery is
available. The unit will run for several months before the battery will need
to be recharged. This makes the product ideal for standalone implementations
in remote areas, warehouses, farms, plots or sites. For technical support,
please contact your VALARM dealer, or contact us at

View the FAQ on our website for typical questions answered. Also view the
VALARM video on Youtube on DisrupterSA. It is good practice to test any
security system frequently, to ensure satisfactory and reliable operation, and
ultimately ensuring your safety. The same is recommended for the VALARM
product.
