The 918 EntryCheck™ is a digital keyless entry system designed for
access control applications. The keypad is mounted on a rugged,
stainless steel faceplate and is designed to be mounted in a standard
single-gang electrical box. The indoor 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 918 EntryCheck™ is powered from a 12-24V AC or DC source.
The 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.
