Number of Alert Units

The number of alert units is

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, 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 drives

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.

2.3 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.

2.3.1 Verify Each Potential Receiver

Location

Using a standard receiver in Receiver

Spacing Mode

Receiver Spacing Mode is enabled with

Jumper P5 in place (Jumper P4 removed)

on a standard receiver (see the EA102

Receiver Installation Instructions).

This mode is exactly the same as the

Test Mode, except 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. Mount the first receiver. Put

jumpers P1, P2, P3, and P5 in

place, remove all other jumpers.

Power the receiver from a 9 VDC or

12 VDC source.

2. Take the second receiver and a

transmitter a distance away from

the first receiver.

3. Activate the transmitter.

4. 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.

Note:

Do not use the Test Mode (Jumper

P4) to determine receiver spacing.
