门禁如何连接电锁?作

介绍

概述

本文档是介绍门禁如何连接电锁,当电锁的启动电流小于 12V/500mA 时通过门禁进行供电,此为内部供电模式;当电锁的启动电流超过 12V/500mA 时门禁只是作为短路输出控制电源需电锁自身供应,此为外部供电模式。这两种模式由跳线 JP1 控制,具体连接方法可参考此文档介绍的方法进行操作。

操作指南

什么是Fail-safe 锁和 Fail-secure 锁

Fail-safe:断电开门(通电上锁)型电锁
Fail-secure:断电关门(通电开锁)型电锁
Fail-safe 锁:当电源中断或出现故障时,fail-safe 类型的电锁会自动解锁,以使人员逃离危险空间。 这就是为什么他们被称为“安全”的原因-他们对人是安全的,而不是空间。
Fail-safe 锁通常用于主要用于出入口处,例如办公室大门或大厅大门。
Fail-safe 锁Fail-secure 锁
Fail-secure 锁:断电时,Fail-secure 锁被锁定。
Fail-secure 锁用于金库,IT 室等一些财产保险行为较高的门禁场合。 它们也可以用于防火门或楼梯门。 万一发生火灾,这些门将会保持关闭以密封部分空间,防止火势蔓延。

如何确定电锁工作模式

贝克门禁和视频支持内部供电和外部供电两种供电模式,默认设备是外部供电模式。
内部供电模式:当电子锁的启动电流小于 12V / 500mA 时,可以使用内部供电模式,电锁的接口为 12V DC 输出。
外部供电模式:当电子锁的启动电流超过 12V / 500mA 时,需要使用外部驱动模式,电锁接口为短路输出控制。
注意:
1)这里的 500mA 是包括启动瞬时电流,一般来说,启动瞬时电流会大于正常工作电流。如果连接了大于 500mA 的电锁,会出现一种现象, 在尝试开锁的时候,设备会重启。(有过流保护)
2)内部供电模式,电锁不能接外部电源,如果误接,会把输出口继电器烧坏

连接前注意事项

在连接之前请注意:
1)确定好电锁类型,fail-safe 或是 fail-secure
2)确定电锁规格,启动电流是否小于 12V / 500mA;
3)开始连接

内部供电模式

Step1.检查电锁的规格,确保电锁的工作电压为 12V,最大电流为 500mA。
Step2.检查确定电锁类型是否是 fail-secure 或 fail-safe,若两者均不是,不可使用内部供电模式。
Step3.确认 JP1 跳线模块已连接,连接 pin1 和 pin2,并连接 pin3 和 pin4。
Step4.根据锁的类型,将电锁连接到门禁的 COM-NC 或 COM-NO 接口。

内部供电模式的优势:
安装位置通常在接口有限的门附近,内部供电模式不需要外部电源。使用该方式,安装更简便,成本更低。
注意:i33V / i32V 仅在短路输出口 1 支持内部供电模式。

外部供电模式

Step1.检查电锁的规格,确保电锁的最大电压和电流符合门禁继电器的规格。

Step2.确认 JP1 连接,连接 pin2 和 pin3,pin1 和 pin4 留空。
Step3.当使用无源模式时,NC-COM / NO-COM 则充当锁和外部电源之间的ON / OFF 开关。
1)将外部电源的正极连接到电子锁的正极;
2)将外部电源的负极连接到门禁的 COM 端口
3)根据锁的类型,将电子锁的负极端口连接到门禁的 NC 或是 NO 端口。
