1. Description
The GTR057 is a two relays multifunction standalone
access controller. It is suitable for mounting either
indoor or outdoor in harsh environments. It is housed
in a strong, sturdy and vandal proof zinc alloy
electroplated structure. The electronics are fully
potted, so the keypad is waterproof and conforms to
IP65.
It supports up to 1200 users in either a card, pin, or a
card + PIN option. The built-in card reader supports
125KHz EM frequency card, and the PIN length is 4-6
digits.
Both of the two relays on board can operate in Pulse
Mode (suitable for access control) or Toggle Mode
(suitable for arming/disarming alarms, switching lights,
machines…etc)
The GTR057 is an ideal choice for door access not
only for small shops and domestic households but
also for commercial and industrial applications such
as factories, warehouses, laboratories, banks and
prisons.
