The 920 Indoor/Outdoor Keypad Surface Mount EntryCheck™ is a digital
keyless entry system designed for access control applications. The
keypad is integrated in a heavy cast vandal resistant housing, designed to
be mounted on a rugged, surface mounting plate and may be mounted in
a standard single-gang electrical box. The indoor/outdoor backlit keys
have bright, easy-to-read graphics.
Up to 500 entry codes, from 1 to 6 digits in length, can be programmed.
They can activate either, or both of the relay outputs. The "anti-passback"
feature prevents using the same code again before the programmed time
elapses.
All system indicators are long-lasting, solid state LEDs. Two indicators
show the status of the entry system. The left indicator lights red to
indicate power, then turns green when access is granted. The right
indicator lights yellow when the keypad is in "lockout" condition (from too
many incorrect code entries). The yellow LED flashes when the keypad is
in programming mode. An internal sounder beeps when each key is
pressed. An internal jumper sets the sounder volume high or low
The SENSE input can be used two ways. If programmed for "door sense"
the input is wired to a normally closed switch on the door to detect when
the door is opened or closed. Forced entry or door ajar situations can
then be detected. Using door sense, the "Auto-relock" feature will prevent
"tailgating" by turning off the Main Relay output immediately when the
door is closed after access has been granted. If the SENSE input is
programmed for "inhibit", the input can be wired to a "service" switch or
automatic timer that will disable the Main Relay when required.
The REQUEST-TO-EXIT input can be wired to a pushbutton to provide
codeless activation of Main Relay, Auxiliary Relay, Output #3 or Output #4
(programmable).
The ALARM SHUNT output activates when access is granted. This
output can be wired to shunt alarm contacts on the access door/gate to
prevent triggering of an alarm when authorized access occurs.
The 920 EntryCheck™ is powered from a 12-24V AC or DC source.
EEPROM memory retains all entry codes and programming, even without
power. An internal jumper is provided to reset the master code. The Main
Relay has a 5 Amp capacity. The Auxiliary Relay has a 2 Amp capacity.
Two solid state outputs, capable of switching 100 mA to common, are
programmable to signal forced entry, door ajar, lockout, alarm circuit
shunting, request-to-exit, and keypad active conditions.
