3. Siren:
Built-in 90dB(A) siren is triggered by an alarm and can be switched of (silent alarm) via the
keyboard after entering your personal access code (PIN).
4. Battery compartment:
Contains a back-up battery in case of a power failure or tampering. For longer back up times
a 9V alkaline (approx.10h) or Lithium battery (approx. 30h) can be used. Battery lifetime is
reduced each time the power is switched off or the power adapter is disconnected from mains.
If the HomeGuard is disconnected from mains for a longer period of time on purpose, remove
the battery first.
5. Status indicators:
red: • On continuously when the alarm is activated.
• flashes after the alarm has been triggered.
• is off when the alarm is de-activated.
green: • flashes when the device is being programmed.
• flashes when the device is being turned on (time delay).
• On continuously when the device is on.
6. Telephone input:
Connects the HomeGuard to the public telephone network with the supplied cable.
7. Power supply:
Only use the supplied 12V power adapter.
8. External alarm connector:
This input allows you to connect any external alarm device with a non-powered NO (Normally
Open) or NC (Normally Closed) connector. E.g. smoke alarms, magnetic door/window
connectors, flood and temperature detectors, etc. There may be multiple sensors connected
to the HomeGuard (serial for NC, parallel for NO alarm connectors). This allows you to turn
your HomeGuard into a complete security system with built-in telephone dialler. To connect
any external security device, use the supplied cable with mini-plug or install an equivalent jack
plug on these devices.
