The EntryCheck™ 920 Indoor/Outdoor Keypad is a surface-mount digital
keyless entry system designed for access control applications. The backlit
keys are bright and easy-to-read. A heavy cast vandal resistant housing
design with mounting plate allows the 920 to be mounted on a rugged
surface or on a standard single-gang electrical box.
The 920 has a capacity of 500 users. Users can be assigned to use 4 to 6
digit PIN codes. An authenticated access can be programmed to activate
one or both of the onboard relay outputs.
The timed "anti-passback" feature prevents using the same credentials
twice before a programmed waiting period has elapsed.
Two long lasting solid state LED indicators show the status of the system.
The left bi-color indicator lights red to indicate power, then solid green when
a relay is active (access grant, etc.). The right indicator flashes yellow to
indicate that the keypad is in programming mode.
An internal sounder can be programmed to beep each time a key is
pressed or when an output is activated. An internal jumper sets the
sounder volume high or low.
The SENSE input can be configured two ways through programming .
When configured for "Door Sense", the input is wired to a normally closed
door position switch to detect when the door is opened or closed. Forced
entry or door ajar situations can then be detected. The "Auto-relock" feature
can also be used to turn off the Main Relay output immediately when the
door is closed after access has been granted to prevent "tailgating".
When the SENSE input is configured for "Inhibit", the input can be wired to
a normally open "service" switch or automatic timer that will disable access
while the switch is closed.
The REQUEST-TO-EXIT input can be wired to a normally open pushbutton
to provide codeless activation of the Main Relay, Auxiliary Relay, Output #3
or Output #4 (user programmable).
The ALARM SHUNT signal is available when access is granted. This
signal can be programmed to activate any of the relays or solid state
outputs to shunt alarm contacts on the access door/gate preventing the
triggering of an alarm when an authorized access occurs.
The 920 EntryCheck™ is powered from a 12-24V AC or DC source. The
non-volatile EEPROM memory retains entry codes and programming when
power is removed. 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 sinking 100 mA to common
are programmable for alarm shunting, or to signal forced entry, door ajar,
keypad lockout, request-to-exit, and keypad active conditions.
