Alarm messages
Enter an individual alarm text by means of the voice recording facility. You can record up to 4 messages.
The maximum length of all alarm messages is 32 seconds. In case of an alarm the TWG 01 will send the
selected messages during the selected interval of 50, 70, 90 or 110 sec. If the recorded message is
shorter it will be repeated accordingly. For each call group there is a special combination of messages
(chap. 6.3).
2.6
Electric power supply
For the electric power supply the TWG 01 requires 12 V DC/100 mA max. taken from the delivered
stabilized power supply unit. Do not use any different connection or power supply unit because this could
damage the TWG 01.
Do NOT use the TWG 01 outdoor, in humid locations or in explosive areas. This is not permitted and can
lead to faults and to damage, including the connected devices.
2.7
Power failure
All settings, recorded messages and entered phone numbers remain stored in case of power failure. To
ensure alarm transmission during a power failure we recommend taking the electric power supply from a
central alarm facility with a power supply buffered by a 12V accumulator which is permanently loaded by
a charger suitable for permanent loading.
To enable alarming during a power failure, the APT-COM™ computer, if appropriate the monitoring
computer (Watch Tool), and the Alarm Box AB 01 must be connected to an interruption free power supply
(e.g. battery buffer for PCs).
All phone numbers, messages and programming are conserved in a fix memory even in case
of a power failure.
2.8
False alarms
Never program telephone numbers of the police or the fire service. This is not permitted.
Please consider that you will have to pay for calling the police when it has provoked alarms.
By mistake the manual alarm-key could release an alarm. You can protect yourself against
such a false alarm by installing the unit as inaccessibly as possible.
