user may initiate and accept a call, hold communication session in BTC user
network with / without connection to power mains;
c)
operation from an inductor (manual generator) or external PSU in the following
modes:
– pair communication – between two users;
– general list (all) or selective conference call – between all or selected us-
ers (max. 25 users);
d)
communication session (for pair communication) with min. length
10 minutes – after one rotation cycle of generator (max. speed 3 rot/sec during
3…5 sec) or more, if an inductor handle was rotated for the second time;
e)
possibility to hold communication:
– in individual means of respiratory protection (using external communication
devices with throat microphones);
– in environment with increased level of noise (max. 130 dB) – using individual
means of hearing protection (headset or intercom helmet);
f)
telephone communication up to 20 m due to extended cord of communication
device (headset or intercom helmet);
g)
telephones and commutator telephones provide for intermittent sound and light
signaling of outgoing call. Сommutator telephones additionally provide for light signal-
ing of selected user line;
h)
telephones and сommutator telephones provide for flashing sound and light
signaling of incoming call. Сommutator telephones additionally provide for light indica-
tion of calling user;
i)
external call signaling units may be connected to telephones and сommutator
telephones (except сommutator telephone PH2-5C-PO); they may repeat incoming call
signaling (if power supply is available) and reset current alarm as well;
j)
electric generator status (inductor) and power supply is controlled by constant
