MODEL B SERIES
SINGLE CHANNEL LOOP DETECTORS
INSTALLATION AND OPERATING INSTRUCTIONS
I. General
Please verify source voltage before applying power. The model designation indicates the input power required, output
configuration, sensitivity boost configuration, and Fail-Safe / Fail-Secure configuration for the detector as follows.
Model B-xx-xx-x Blank = Fail-Safe, S = Fail-Secure
Blank = Internal DIP switches set to True Presence
TM
/ Pulse-on-Entry
DP = Internal DIP switches set to True Presence
TM
/ True Presence
TM
SB = Internal DIP switch set to enable Sensitivity Boost
3 or 1 = 120 VAC
4 or 5 = 12 VDC / 24 VDC / 24 VAC
8 or 35 = 240 VAC
NOTE: Models B-3, B-4 and B-8 are fitted with a rear mounted, 11 pin, and Amphenol style connector. Models
B-1, B-5, and B-35 are fitted with a rear mounted, 10-pin, MS style connector.
The detector is factory configured for either Fail-Safe or Fail-Secure operation (see unit side label). The output state of
each output relay in either Fail-Safe or Fail-Secure mode is listed in the table below.

II. Indicators and Controls
i. Power / Detect / Fail LEDs
The detector has one green and two red LED indicators that are used to provide an indication of the detector’s
power status, output state, and/or loop failure conditions. The table below lists the various indications and their
meanings.
Status
PWR (Power) LED
DET (Detect) LED
FAIL LED
Off
No power or low power
Output(s) Off
Loop OK
On
Normal power to detector
Output(s) On
Open Loop

4 Hz (50% duty cycle)
Two second timing
delay activated
1 Hz (50% duty cycle)
Shorted Loop
1 Hz (5% duty cycle)
Waiting for release of FREQ push-
button to enter diagnostics mode
(See Failed Loop Diagnostics)
NOTE: If the supply voltage drops below 75% of the nominal level, the PWR LED will turn off, providing a
visual indication of low supply voltage. Model B detectors will operate with supply voltage as low as 70% of
nominal supply voltage.
ii. Frequency LEDs:
The four red LED indicators provide an indication of the current detector operating frequency.
iii. Front Panel Pushbutton Switches:
Two momentary contact pushbutton switches are used to control the following.
RESET - Push the front panel mounted pushbutton labeled RESET to reset the detector.
