security alert feature
12
Effective for shipments after this date of new or reprogrammed units. Serial numbers
beginning with A19 and later (letter or number is A, B, C… and number is 19, 20, …).
The Maxim III security alert feature, when triggered by an IRT-60 sapphire mic on
Channel A, creates a relay contact closure or opening. The back panel connection
is a normally closed and normally open terminal paired with the common terminal.
Note: the wireless channel B does not trigger security alert.
The Maxim III may be set to provide either 4- or 1-pulse signal at the relay. This
new feature allows the user to change from 1 to 4 pulses, or 4 to 1 pulse. Different
monitoring systems may require one or the other.
The steps below describe how to select either the 1-pulse or 4-pulse mode and how
to determine/confirm the Maxim III’s selected mode.
Ordinarily, the Maxim III will arrive new with the 4-pulse mode selected by default.
Installers should nevertheless confirm the mode upon installation if the security
alert feature will be employed. Once set, the mode is active and should remain set
until such time as it is manually changed as detailed below.
The output on the amplifier is a three pin COM, N/O, N/C contact closure labeled
"SECURITY ALERT".
