Description
The SE receivers are located throughout the protected area, including building interiors.
Each SE receiver contains a radio receiver to detect the transmissions from SE transmitters,
and a microcomputer to decode and interpret the received test and alarm messages. In
addition, the microcomputer monitors tampering and other problems, and reports such
conditions to the SE coordinator.
Each SE receiver contains an internal self-contained sounder. These sounders are optionally
activated if the SE receiver has detected an alarm transmission.
Indoor SE receivers are typically mounted on inside walls and are housed in small beige,
rectangular units. Indoor SE receivers have one red and one green light. The green light is
used to indicate a successful test of an SE transmitter; the red light is only illuminated during
certain system tests and during alarms.
Outdoor SE receivers are contained in small weatherproof enclosures typically mounted on
the sides of buildings and on light posts. Outdoor SE receivers do not have the visible red and
green LEDs. Outdoors, the strobe lights connected to the SE receivers flash to acknowledge a
successful test.
Function during an alarm
In the event of an alarm, the SE receivers detect an alarm signal from an SE transmitter and
send this information to the SE coordinator. The SE coordinator forwards this information the
Central Console where, using the reported information from all the SE receivers that detected
the signal, the location of the transmission is graphically displayed on the Alarm Map.
Buddy check
In addition to its radio receiver, each SE receiver also contains a transmitter functionally
similar to the hand held SE transmitters. This transmitter can be commanded by the Central
Console to transmit a test message to other nearby SE receivers. This Buddy Checking is
performed periodically to verify that the SE receivers are functioning satisfactorily. Results of
the Buddy Check are compared with the results of earlier Buddy Checks, and any changes in
an SE receiver's sensitivity are reported to the Central Console where this information is
stored in a system database.

Built-in self testing through Buddy Check feature.
Indoor and outdoor security enclosures available.
Indoor enclosure provides confirmation of successful SE transmitter test (outdoor
enclosures use other type of signaling device, such as a horn/strobe).
Indoor SE receivers provide local sounders in alarm events.
