Pre-Construction Coverage Verification Survey; Verify Each Potential Receiver Location - Bosch Security Escort SE2000 Series Training Manual

Security Escort
Bus wire
The multiplex bus for transponder should be wired with 4 conductor 18 gauge (1.2 mm) wire.
The wire should not be paired or shielded. In the United States this is the same as fire system
wire, except it should not be red.
Number of alert units
The number of alert units will be determined by each system's requirements. In general,
enough alert units should be installed to be heard and seen from all outdoor locations of
protection. Remember that even in a silent system, alert units can be used outside to provide
test feedback. Horn/strobe units should be mounted in predictable locations to make them
easy to identify by subscribers. Alert units are not required indoors because the indoor
receiver provides alarm and test feedback. Each transponder will drive one siren and one
strobe if they are less than 15 m (50 ft) from the transponder.
It is a good idea for each protected parking lot to have a siren/strobe near it.

Pre-construction coverage verification survey

The pre-construction coverage verification survey is performed after the bid is accepted and
before construction begins. It is done to determine the location of each receiver. Each receiver
location should be checked using a standard receiver in the test mode.
3.3.1

Verify each potential receiver location

Using a receiver in "receiver spacing" mode
"Receiver spacing" mode is enabled with jumper P5 in place (jumper P4 removed) on a
receiver (see the EA102 Receiver Installation Instructions).
This mode is exactly the same as the "test" mode, except that only transmissions with an
adequate receive margin are sounded. This indicates the maximum acceptable spacing of
receivers. Use the following procedure to test the spacing of receivers:
1.
2.
3.
4.
5.
Notice!
Do not use the "test" mode (jumper P4) to determine receiver spacing.

Mount the first receiver.
Put jumpers P1, P2, P3, and P5 in place, and remove all other jumpers. Power the
receiver from a or 12 VDC source.
Take the second receiver and a transmitter a distance away from the first receiver.
Activate the transmitter.
If receiver 1 sounds the test beep, receiver 2 is within range. Repeat this test until
receiver 1 no longer sounds the test beeps. Move back to the last location where receiver
1 received the test beeps. This location marks the maximum spacing between receivers.
The distance between receivers should not exceed 25 m (80 ft) indoors and 90 m (300 ft)
outdoors. Mount receiver 2 at this location or closer to receiver 1.
