MGT OBSTACLE TRANSMITTER OPERATION
One Model MGT obstacle transmitter can be programmed into the AKR-1. The
MGT is triggered with a safety edge contact and will activate the AKR-1 Relay #2
for the programmed length of time.
☞ NOTE: If an MGT transmitter is programmed, all other transmitters or entry code activations
programmed for Relay #2 will be blocked.
MGT Supervisory Mode
If an MGT supervisory condition occurs the AKR-1 will beep every 5 seconds. In
addition, all users will have to enter their entry code twice (within one minute), or
activate their transmitter twice (within ten seconds) to request access.
The MGT can monitor and produce three supervisory conditions: low battery, case
tamper/loop fault, and status. To determine the supervisory condition place the
AKR-1 in MGT supervisory mode, the same command is used to exit this mode:
Press the * , # , and “2” buttons
together for two seconds
While in MGT Supervisory Mode, the following conditions can be displayed:
Low Battery
If the transmitter detects a low battery, it will send a low battery supervisory report.
The keypad’s yellow indicator will blink.
Tamper/Loop Fault
If the transmitter case is opened or the safety edge contact becomes defective,
it will send a tamper/loop fault supervisory report. The keypad’s red indicator will
blink.
Status
Status reports are sent every hour. If no status reports are received for eight hours,
a status exception condition occurs. The keypad’s green indicator will blink.
RADIO TEST MODE
A special mode is provided to test transmitters and determine if there is radio
frequency interference present. The keypad will function normally while it is in
Radio Test Mode. To enter Radio Test Mode, use the following command:
Press the * , # , and “0” buttons
together for two seconds
The AKR-1 will beep once when the Radio Test Mode is entered. The keypad’s
yellow indicator will blink quickly when radio signals are detected. If a Linear
MegaCode transmitter is detected, the AKR-1 will beep once when the transmission
is decoded. The AKR-1 will automatically exit Radio Test Mode 45 seconds after
the last MegaCode signal is decoded.
