SDC EntryCheck 918 - User Manual

To Next Page

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 one or both of the relay

outputs. The programmable “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 door contact

switch to detect when the door is opened or closed. Forced

entry or door ajar situations can then be detected. When using a

door contact switch, 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 may 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 12/24VDC or AC

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.

Do you have a question about the SDC EntryCheck 918 and is the answer not in the manual?

The SDC 918 EntryCheck™ is a digital keyless entry system designed for access control applications. It features a rugged, stainless steel faceplate and is designed for mounting in a standard single-gang electrical box. The indoor backlit keys provide bright, easy-to-read graphics.

Function Description:

The 918 EntryCheck™ allows for programming up to 500 entry codes, each ranging from 1 to 6 digits in length. These codes can activate one or both of the system's relay outputs. A programmable "anti-passback" feature prevents the same code from being used again before a programmed time elapses.

The system includes long-lasting, solid-state LED indicators. The left indicator lights red for power and turns green when access is granted. The right indicator lights yellow to indicate a "lockout" condition (triggered by too many incorrect code entries) and flashes yellow when the keypad is in programming mode. An internal sounder provides audible feedback with each key press, and its volume can be adjusted via an internal jumper.

The SENSE input offers dual functionality:

Door Sense: When programmed for door sense, this input connects to a normally closed door contact switch. It detects when the door is opened or closed, allowing for detection of forced entry or door ajar conditions. With a door contact switch, the "Auto-relock" feature immediately turns off the Main Relay output when the door closes after access has been granted, preventing "tailgating."
Inhibit: When programmed for inhibit, the input can be wired to a "service" switch or automatic timer to disable the Main Relay when required.

The REQUEST-TO-EXIT input can be wired to a pushbutton to provide codeless activation of the Main Relay, Auxiliary Relay, Output #3, or Output #4 (programmable).

An ALARM SHUNT output activates when access is granted. This output can be wired to shunt alarm contacts on the access door/gate, preventing an alarm from triggering during authorized access.

The 918 EntryCheck™ is powered by a 12/24VDC or AC source. Its EEPROM memory ensures that all entry codes and programming are retained even without power. The Main Relay has a 5 Amp capacity, and the Auxiliary Relay has a 2 Amp capacity. Two solid-state outputs, capable of switching 100 mA to common, are programmable to signal various conditions such as forced entry, door ajar, lockout, alarm circuit shunting, request-to-exit, and keypad active.

Tactile Key Feel: Keys provide a responsive feel.
Audible Code Entry Verification: Sounder confirms key presses.
Power Options: Operates on 12 or 24V, AC or DC.
Toggle Mode: Outputs can be programmed to alternate between OFF and ON with each activation, useful for extended access periods (e.g., normal business hours).
Master Code Reset: An internal jumper (JP2) allows for resetting the master code to its default (123456) without clearing other programming.
Factory Defaults: The system comes with pre-set default values for all programming options, including a Master Programming Code of 123456, 4-digit entry code length, and 2-second activation times for relays and solid-state outputs.

Maintenance Features:

Master Reset: A full master reset procedure (disconnect power, hold * and # keys, apply power, release keys) clears all memory and returns all programmable options to factory default values, erasing all entry codes.
Beeper Sound Level: An internal jumper (JP1) allows for adjusting the beeper sound level (high or low).
EEPROM Memory: Retains all entry codes and programming even during power loss, minimizing reprogramming needs after outages.
Troubleshooting Indicators: Red and yellow LEDs provide visual cues for incorrect entries, programming errors, and lockout conditions, aiding in troubleshooting.
