Access Control Systems

we stand behind everything we do!

Properties protected by a Johns Brothers system can result in an alarm or at least a timed lockout to prevent "experimenting" with possible codes.

Systems and Bypass Codes

Johns Brothers Security is equipped, staffed and experienced in the installation of Access Controls in all manner of businesses and their facilities.
To be useful, any intrusion alarm system is deactivated or reconfigured when authorized personnel are present. We can establish a system under which authorization may be indicated in any number of ways, often with keys or codes used at the control panel or a remote panel near an entry.

High-security alarms may require multiple codes, or a fingerprint, badge, hand-geometry, retinal scan, encrypted response generator, and other means that are deemed sufficiently secure for the purpose.

Properties protected by a Johns Brothers system can result in an alarm or at least a timed lockout when there exist failed authorizations to prevent "experimenting" with possible codes. Some systems can be configured to permit deactivation of individual sensors or groups. Others can also be programmed to bypass or ignore individual sensors (once or multiple times) and leave the remainder of the system armed.

This feature is useful for permitting a single door to be opened and closed before the alarm is armed, or to permit a person to leave, but not return. High-end systems allow multiple access codes, and may even permit them to be used only once, or on particular days, or only in combination with other users' codes (i.e., escorted).

In any case, we establish in our Central Monitoring Station an oral code to be provided by an authorized person in case of false alarms, so the monitoring center can be assured that a further alarm response is unnecessary. We can also establish systems that permit a duress code to be entered and silence the local alarm, but still trigger the remote alarm to summon the police to a robbery.
