Quik Bridge International Loop Receiver
Installation Sheet
Introduction
The Quik Bridge International Loop Receiver (see Figure 1)
allows you to use up to 16 learn mode wireless sensors (two
per zone) with any standard hardwire control panel. In
addition, you can use up to 45 keychain touchpads and panic
button transmitters, for a total of 61 wireless transmitters.

The receiver monitors the alarm, battery, tamper, and
supervisory status of transmitters learned into the receiver’s
eight zones.
The receiver features the following:
•
Spatial-diversity receiver enhances reception.
•
Eight programmable zone outputs (N/C or N/O).
•
Selectable zone supervision (programmable).
•
RF (radio signal) jam detection on zone 7 (optional).
•
Sensor tamper output summary and receiver
cover/antenna tamper on zone 8 (optional).
•
Two yellow trouble LEDs indicate sensor low battery and
supervisory conditions.
•
Support for a piezo (used for RF testing only) that
sounds the number of transmissions received from
learned transmitters.
•
On-board EPROM stores sensor IDs and programming
information in nonvolatile memory, if power is removed.
•
Selectable 1- or 4-hour RF supervisory.
Transmitter compatibility
The receiver is compatible with all current Learn Mode
sensors (433.92 MHz), panic button transmitters, two- and
four-button keychain touchpads, with the exception of smoke
detectors.
Control panel compatibility
The receiver is compatible with control panels designed with
hardwire loops where the loop negative is ground (common-
loop ground).
The receiver is not directly compatible with powered loops
(two-wire smoke detector loops and glassbreak detector
loops). If the loop on the control panel can power a device, it
must not be connected directly to the loop receiver. Instead,
a relay is required when connecting to powered loops.
Compatibility testing
Typically, hardwire loops have the negative (-) side of the
loop common with ground. If this is true, and the loop is
nonpowered, the loop should be compatible with the
receiver.
Although most control panels are compatible with the
receiver open collector outputs, each loop should be tested
for compatibility before connecting receiver outputs to the
control panel loop outputs. If the receiver is not directly
compatible with a control panel loop, you can use a relay to
establish compatibility.
To check if the negative side of the loop is common to control
panel ground, do the following:
1. Turn off or remove control panel power and disconnect
the back-up battery.
2. Use an ohmmeter and measure the resistance between
the negative side of the loop and panel ground. If the
resistance is zero or close to zero, this loop should be
compatible with the loop receiver. If the resistance is not
zero, a relay is required for this loop.
Test the compatibility for all loops that you are going to
connect to the receiver.
