Equipment Estimation, Location Accuracy and Receiver
Location
General
A Security Escort system installation consists of three major steps. The pre-bid equipment estimation, the pre-
construction coverage verification survey, and the post construction setup. The Security Escort Receivers work
effectively in a wide variety of installations and can be placed with confidence provided these installation
requirements are met. Therefore, at the pre-bid stage, it is acceptable to estimate the required equipment. To
ensure proper coverage after proposal acceptance, potential Receiver locations can be verified using a standard
Receiver in test mode or the portable test Receiver before construction begins.
Location Accuracy
The Security Escort system is intended to provide quick response to a duress call. Its intent is to dispatch a
responding individual to an area that will not add additional delay to their response to that duress call.
The Security Escort system uses radio frequency (RF) for alarm transmissions. This is a significant positive
because it prevents normal construction from blocking the signal and helps to eliminate dead spots where the
alarm could not be heard. The fact that RF energy passes through normal construction also prevents Security
Escort from locating an alarm with 100% certainty to a specific side of a wall. Alarms originating at or near
building walls will typically be indicated within 25 ft. (7.5 m) of the actual location, however there may be times
when the computed location may appear to be on the other side of the wall.
Security Escort system was designed to provide a computed alarm location typically within 25 ft. (7.5 m) of the
actual location when indoors and a computed alarm location typically within 50 ft. (15 m) of the actual location
outdoors. Any deviation from the following installation guidelines will degrade the computed location accuracy.
Therefore to achieve accuracy the following installation guidelines must be adhered to:
