INSTALLATION:
WARNING: REMOVE POWER FROM THE CONTROL UNIT OR INITIATING-DEVICE CIRCUITS BEFORE INSTALLING
DETECTORS.
1. Wire the plug-in screw terminal block per Figure 3.
2. Turn the detector clockwise in the mounting bracket until it clicks into place.
3. After all detectors have been installed, apply power to the control unit or initiating-device circuits.
4. Test the detector as described in the following paragraph.
5. Reset the detector at the system control panel.
6. Notify the proper authorities that the system is in operation.
CAUTION
Dust covers are an effective way to limit the entry of dust into smoke detector sensing chambers. However, they may not completely
prevent airborne dust particles from entering the detector. Therefore, System Sensor recommends the removal of detectors before
beginning construction or other dust producing activity.
Be sure to remove dust covers from any sensors that were left in place during construction as part of returning the system to ser-
vice.
TESTING:
NOTE: Before testing, notify the proper authorities that the smoke detector system is undergoing maintenance and will temporarily
be out of service. Disable the zone or system undergoing maintenance to prevent unwanted alarms.
Detectors must be tested after installation and following periodic maintenance. The 2312/24TB may be tested as follows:
NOTE:
Before testing the detector, look for the presence of the flashing LED. If it does not flash, power has been lost to the detector
(check the wiring), or the unit is defective (return for repair).
A. TEST SWITCH
1. A recessed test switch is located on the detector housing (See Figure 4).
2. Push and hold the recessed test switch with a 0.1 inch maximum diameter tool such as an allen wrench or small screwdriver.
3. The LED on the detector should light within 5 seconds.
B. TEST MODULE (System Sensor Model No. MOD400R).
The MOD400 or MOD400R test module can be used with a DMM or analog voltmeter to check the detector sensitivity as described
in the test module’s manual.
C. SMOKE ENTRY TEST
Hold a smoldering punk stick or cotton wick at the side of the detector and gently blow smoke through the detector until the unit
alarms.
D. DIRECT HEAT METHOD (Hair dryer of 1000-1500 watts).
Direct the heat toward either of the side thermistors. Hold the heat source about 12 inches from the detector in order to avoid dam-
age to the plastic.
The detector will reset only after it has had sufficient time to cool and the power source has been momentarily interrupted.
Both smoke and heat detection testing are recommended for verifying system protection capability.
A detector that fails to activate with any of the above tests should first be cleaned as outlined in the Maintenance section which fol-
lows. If the detector still fails to activate, it should be returned for repair.
Notify the proper authorities that the system is back on line.

MAINTENANCE:
When removing the detector from a system of more than 1 detector per loop, an optional detector bypass plug can be inserted into the
