SAFETY INSTRUCTIONS
1.1
Telephone connection
EasyAlarm® is designed to connect to an analogue telephone line. This network must remain in service for at least one
hour after a mains power loss according to EN81-28.
These are:
analogue PSTN (with EA-8-DPXN in combined use with downstream existing subscriber as modem/fax).
analogue port of an ISDN terminal:
ISDN-NT has to be reprogrammed for emergency operation at the ab-port.
One line must be available at any time.
Mobile interface / Gateway with approval, i.e. from Leitronic
analogue port of a private exchange using UPS (Interruptible power supply 1h buffering).
DECT-Interface
Multiple EasyAlarm® sharing one line:
Ensure that the first alarm number is always available, because if multiple alarms triggered at the same time it is
possible that only first number can be reached.
A maximum of three units can share one line.
In case of star cable routing (max. 15 Ω difference per connection = Calc 2 x conductor resistance!) up to 4 diallers can
be connected. Example: AWG 24 (U72) = 2 x 90 Ω / km => difference in length max. 15 Ω / (2 x 90 Ω / km) = 0.083km.
In case of a two-step-dialling-in
6.9.2 the number of diallers is doubled.
Not suitable:

with local backup
the network (Amplifiers, Fiber network etc.) cannot guarantee EN81-28.
If a "fail-safe" connection is guaranteed, ensure that DTMF-transmission will be real-time
i.e. configure “DTMF
inband” on the ATA (AnalogTelephoneAdapter).
The voltage of the telephone network is defined in EN 41003. It is higher than 40 V and therefore please beware for
electrical hazard and disconnect the phone line whenever working on connections.
The telephone line can be protected with a lightning protection interface
1.2
Power supply
A transformer according to the safety regulation EN60950 provides power supply. 9V battery is used as a back up in case of
power failure. It is located on the rear side oft the device.
In case of a mains power loss in combination with a low battery, EasyAlarm® can still make a call to one destination
powered over the telephone line.
If a relay is used to start emergency call, beware that this relay is powered for at least 1 hour after a mains loss.
1.3
Safety notes
All the electrical connections have to be potential free; therefore no ground connection between elevator control-unit
nor the power supply is permitted. Observe the regulation according to EN60950.
If you hear or o after power on, you have to replace the battery
Check alarm functions and start a test-call, before the system is put in service
Please note, an alarm by telephone is only successful if the subscriber takes care of the following points:
Alarm must not be answered by an answering machine or equal equipment.
Mobile phones can be out of coverage (e.g. underground car park, shielded rooms, remote areas and so on).
Do not open the device (exception: opening of battery compartment).
Do not bring the device into contact with water.
Use only small signal switches or relay contacts for the emergency buttons. Do not use 230 V contact material, since it
may not give a reliable contact.
