SDC EntryCheck 923 Narrow Series

Description

The SDC 923 EntryCheck Narrow series consists of stand alone digital keypads designed to control access of a single entry point for facilities with up to 500 users. Each user is assigned a personal identification number (PIN). Keypad entry of a valid one to six digit code activates one or both of the output relays which releases an electric door lock.The EntryCheck series includes a Door Sense/ Inhibit Input feature. When programmed for “Door Sense”, a door position switch wired into the input and detects a “forced entry” or “door ajar” condition. When programmed for “Inhibit Input”, a maintained switch or automatic timer wired into a the input will disable the activation of the main relay. The EntryCheck also has a request-to-exit input for connection to an exit switch and/or fire access key switch for fire/emergency access. When access is granted, the shunt option is activated shunting alarm contacts on the door or gate. This prevents triggering of an alarm during authorized access.
