3-Gang plate with mortise cylinder bracket and card reader
Model No. LDA9608/9618

Overview

The LDA 9608/9618 Local Door Alarm has field ready mounting for an industry standard proximity mullion type card reader. The LDA 9608/9618 monitors door contacts, motion sensors, and access control devices to determine and annunciate the status of a controlled door. A sounder alerts area personnel of a door control violation, and the building alarm system is notified with alarm relay contacts. The Warning Alarm feature reduces nuisance alarms by sounding a local alarm a few seconds before a Door Held Alarm. An integrated card reader mounted on the plate allows for a very clean and tidy final installation.

The LDA was developed with the intention of reducing nuisance alarms caused by improper door usage, as well as providing flexible door alarm monitoring. Several field selectable operating modes allow system integrators to utilize a single type of door alarm to handle a large variety of alarm applications.
The LDA is designed to complement most access control systems by providing local audible warning and alarm signals to alert area personnel of a door violation, and communicate alarm status to the access control system. The LDA can also be used as a Stand Alone Alarm.
