Controller Questions - Bosch Access Easy Controller 2.1 Hardware Installation Manual

Answer - Yes, as long as the HID proximity readers provides wiegand output and you know the
card format of the cards, you can replace your old access system with AEC2.1 without
changing the readers and the card. Refer to the AEC2.1 Software User Manual for details in
configuration card formats.
Note: 26 bit card formats are evaluated by UL.

Controller Questions

Question - For how long will a fully charged battery maintain AEC2.1 operation during a power
failure?
Answer - Assuming that the standard 12 Volt, 7.0 Amp hour supplied with the controller is fully
charged, it will typically provide four hours of operation during a power outage. This estimate
is based on a controller configured with two 4-Reader boards, each with four readers
connected to it, for a total controller configuration of eight readers. The estimate also
assumes that the readers are HID ProxPro, MiniProx or ProxPoint models.
A controller configured with other than the HID model readers listed above will typically
experience less operational time to standby batteries. Likewise, a controller configured with
less than eight readers can be expected to operate for a slightly longer time on standby
power.
Question - I would like to install an expansion chassis at the other end of the building from
where the controller is located. This will make for shorter cable runs from the expansion
controller to the readers at the end of the building. What is the maximum between the
expansion chassis from the main chassis?
Answer - As the expansion chassis can be connected in the RS485 loop, you could locate it to
a maximum of 1Km away from the main chassis.
Question - Can I get separate controller Tamper alarms for the main AEC2.1 and the expansion
controllers?
Answer - Yes, each controller Tamper can be terminated to the Tamper alarm input of the
interface boards in the Controller. This way you will have individual Controller's tamper
monitored separately, however, whenever there is an activation from either one of the tamper,
the AEC2.1 will announce as controller tampered.
Question - Can the AEC2.1 work with normally closed alarm devices? I already have normally
closed door contacts in place that I would like to monitor with the AEC2.1.
Answer - Yes. Normally closed devices will work with AEC2.1. AEC2.1 can monitor both
normally open and normally closed devices. The controller database is defaulted to expect
normally open type devices; however, it is an easy task to change the setting of any input
point to expect normally closed type operation.
