The SZW-02 code lock can be used as a self-contained device,
designed for electronic control of a single door, e.g. in locations where
it is unnecessary to install an extensive security alarm or access control
system. The lock has a relay output for direct control of the electric
strike, electromagnetic lock or another device with current consumption up to 2
A. SZW-02 can also be used with an alarm system for arming, disarming, etc. The
lock can operate in two modes: monostable (the relay is activated for
a preset time only) and bistable (the relay changes its status until the
password is re-entered). The device is also provided with tamper protection
which responds to opening the enclosure and tearing if off the wall.
The aesthetic enclosure of the lock is oblong in shape. Installed in its
right-hand part are three colored LEDs which indicate the device status (you
can program any function for one of them). On the left-hand part of the lock
enclosure you can find legible keys, which are protected by a flip cover.
Green backlighting of the keys makes the device easy to use even in places with
low light.
