Figure 3-11: 4-Wire Smoke Detectors
Using Smoke Power Reversal Module
The 333 PRM Polarity Reversing Module is used to
reverse the polarity of the positive and negative
voltages powering smoke detectors. The module is for
use with 4-wire smoke detectors that employ a sounder
and voltage-reversing feature. The module is triggered
by a pulsing bell output.
Smoke Detectors Compatible with the 333PRM
The 333PRM may be used with the System Sensor
2112/24AT and similar models with the required
operating features previously stated.
Installing the 333 PRM
Mount the 333 PRM inside the control panel’s cabinet
or in a separate cabinet using the double-sided tape
provided. Wire the 333PRM as shown in Figure 3-12.
Refer to the 333PRM Installation Instructions for
detailed information on the installation of the module.

For all above controls, 4-wire smoke detectors may only be used on Zone 1.
Figure 3-12: Wiring 4-Wire Smoke Detectors to a
333PRM
The 333PRM reverses polarity to smoke
detectors with Integral Temp-3 Sounders.
Typically, in alarm, each draws 49-60mA of
current. The control panel supplies only
enough current for one smoke detector. In
order to attach more than one, an external
power supply and an external relay may be
required.
Using 2-Wire Latching Glassbreaks on Zone 8
Zone 8 can support 2-wire glassbreak detectors. The
zone provides enough standby current to power up to 50
2-wire glassbreak detectors meeting the requirements
listed below.
Compatible Glassbreak Detectors
Use detectors that meet the following ratings:
Standby
Voltage: 5VDC–13.8VDC
Standby
Resistance:
Greater than 20k ohms (equivalent
resistance of all detectors in parallel)
Alarm
Resistance: Less than 1.1k ohms (see note below)
Alarm
Current: 2mA–10mA
Reset Time:
Less than 6 seconds
NOTES:
•
You can use detectors that exceed 1.1k ohms in
alarm, provided they maintain a voltage drop of
less than 3.8 volts in alarm.
•
The IEI 735L Series detectors have been tested and
found to be compatible with these ratings.

Figure 3-13: Wiring Latching Glassbreaks to Zone 8
•
The alarm current provided by zone 8
supports only one glassbreak detector in
the alarmed state.
•
Do not use other N.O. or N.C. contacts
when using glassbreak detectors on zone
8. Other contacts may prevent proper
glassbreak detector operation.
To wire 2-wire latching glassbreak detectors to zone 8,
perform the following steps:
Step Action
1 Select compatible 2-wire glassbreak
detectors that meet the requirements stated
previously.
2 Connect detectors across zone 8 (terminals
21 and 22). See Figure 3-13.
3 Connect the EOL resistor at the last
detector in the loop across the zone’s
terminals. You must connect the EOL
resistor across the loop wires at the
last detector.
