Thank you for purchasing the S37 alarm system. Please read this guide carefully to familiarise yourself with the alarm’s features and operating procedures, and keep a copy for future reference.
Standard Installation
Optional remote controls are available to operate the alarm system and the central door locking (CDL), but only where a negative CDL connection is available, discuss this with your installation dealer. A standard installation usually includes the following protection:
- Cab Door Protection — Cab doors are usually protected through the vehicle’s own electronics system (CANBUS). On ‘A Class’ vehicles, a wireless magnetic switch is usually required.
- Internal Ultrasonics — Internal sensors that trigger on movement within the cab area.
- Bonnet Switch — May require an additional switch or use the CANBUS system, depending on the model.
- Habitation / Garage & Locker Door Protection — Usually a wireless magnetic switch.
Operation
Operation varies depending on the base vehicle and type of motorhome. Most van-conversion and coach-built motorhomes have central locking, and in most cases the alarm can be programmed to work with your optional remote key, so locking and unlocking your doors also arms and disarms the alarm. Likewise, using the optional S37 remote to arm/disarm will lock/unlock the vehicle at the same time.
Use the button with the locked padlock to arm the alarm, and the button with the open padlock to disarm it. The optional S37 remote has a small central blue LED that flashes momentarily to confirm operation; if the blue light flickers, the internal battery is running low and should be replaced as soon as possible. The remote battery type is CR2016.
If your installer has configured audible chirps, arming and disarming are signalled by: 1 chirp = ARMED, 2 chirps = DISARMED. This can be turned on or off, speak to your installing dealer or call us on 01257 249 928. Please note: for most vehicles, the hazard flash on lock/unlock only occurs when using the vehicle remote.
Once armed, there is a 30-second delay before the system is fully active; during this period the status LED stays on. After 30 seconds the LED flashes once per second to confirm the alarm is live.
If you have an ‘A Class’ motorhome, the arm/disarm process may vary. Many ‘A Class’ vehicles have a manufacturer key whose remote buttons have no functionality, so you’ll use the S37 remote exclusively. Fiat ‘A Class’ installations can use both Fiat and alarm remotes to arm/lock. On Mercedes ‘A Class’ vehicles, only the Mercedes remote locks the doors and arms the alarm; the alarm remote will only arm and disarm (it won’t trigger central locking).
LED and Override Receptacle
The LED (the fitted alarm dash light) flashes to indicate alarm status and is also used during programming and for diagnostic information. If you return to the vehicle and the alarm has triggered, the indicator lights or siren chirps will flash 5 times on disarm (instead of the usual 2).
Pet / Night Mode
Pet/Night mode disables the internal sensors and allows movement within the vehicle while keeping the perimeter armed. There are three ways to set it:
- Double lock-button press: press lock on the vehicle remote (the doors lock and the alarm arms), then, after a minimum of six seconds but no longer than 29 seconds, press lock again: a BOP tone (if configured) confirms the internal sensors are disabled. This option is vehicle-model dependent.
- Use the S37 remote: press the button on the bottom left of the remote once; the alarm arms as usual but excludes the internal sensors.
- Using the touch key: with the ignition off, touch the override key to the dashboard receptacle (the LED gives a quick flash), close all doors, then press lock on the vehicle’s original remote: the alarm arms as usual but excludes the internal sensors.
Please note: you must repeat the chosen process each time you wish to arm in Pet/Night mode.
Service / Valet Mode
Service mode temporarily disables the alarm. We suggest using it only in extreme circumstances, as the alarm must be reset afterwards and the process is easy to forget. To set it: arm the alarm as usual while inside the vehicle, then touch the override key to the receptacle: the alarm is now completely inactive. To exit service mode, touch the override key to the receptacle again; a high-pitched beep and a flash of the LED confirm normal operation (ensure the doors are closed and the ignition is OFF during this process).
Notes
To identify the cause of the last alarm, turn the ignition key on and count the number of flashes from the red LED on the override receptacle. The remote battery type is CR2016.
Frequently Asked Questions
My motorhome is an ‘A Class’, why won’t the vehicle key arm the alarm?
On many ‘A Class’ motorhomes the manufacturer key’s buttons have no functionality, so you use the S37 remote to arm/disarm. On Mercedes ‘A Class’ vehicles only the Mercedes remote locks the doors and arms the alarm; the alarm remote only arms/disarms and won’t operate the central locking.
How do I keep the alarm on while my pet is inside?
Use Pet/Night mode, which disables the internal sensors while keeping the perimeter armed. You can set it via a double lock-button press, the bottom-left button on the S37 remote, or the touch key, and you’ll need to repeat it each time you arm this way.
The blue LED on my remote is flickering, what does that mean?
A flickering blue LED indicates the remote’s internal battery is running low. Replace it as soon as possible; the remote battery type is CR2016.
