STI-6400 Series Exit Stopper Instruction Manual

STI-6400 Series Exit Stopper

Product Information

The STI-6400 Series is a mechanical switch product designed for various applications. It features a polycarbonate enclosure that is UL94 V-2 rated for flammability. The dimensions of the enclosure are 5.375 inches wide, 5.375 inches high, and 2 inches deep (137mm x 137mm x 51mm). The wall thickness of the enclosure is 0.12 inches (3.05mm). This product is powered by a 9VDC battery. If the battery is not being used, there is a slide switch (switch 6) that can be used to turn off the power source. In case the power source is turned off, the installed battery will act as a backup power source. The STI-6400 Series also has a remote power input option, which allows it to be powered by an external power source of 12VDC to 24VDC with a current rating of 300mA. It features a horn with adjustable volume settings. At a distance of 30 cm, the high volume produces a sound level of 112dB, while the low volume produces a sound level of 97dB. At a distance of 100 cm, the high volume produces a sound level of 102dB, while the low volume produces a sound level of 88dB. The product has a low battery detection feature that flashes once per minute and beeps once every three minutes when the battery is running low. It also has relay contacts with a rating of 0.5A at 125VAC and 1A at 30VDC.

Product Usage Instructions

1. Ensure that the product is installed in a suitable location according to the specific application requirements.

2. If using the battery as the power source, make sure a 9VDC battery is properly installed in the product.

3. If not using the battery, slide switch 6 to the “on” position to activate the remote power input.

4. If using the remote power input, connect a power source with a voltage rating between 12VDC and 24VDC and a current rating of 300mA to the appropriate terminals.

5. To adjust the volume of the horn, locate the volume control settings on the product and adjust accordingly. Higher settings will produce louder sound levels.

6. Monitor the low battery detection feature. If the battery is running low, it will flash once per minute and beep once every three minutes. Replace the battery promptly to ensure proper
   functionality.

7. If necessary, utilize the relay contacts for connecting external devices. Make sure to adhere to the specified voltage and current ratings to prevent damage.

Warnings
All units are recommended for indoor use only. Unit must be tested periodically to verify the life of battery. STI recommends you change the 9 Volt battery twice a year. To hear alarm when normal work environment is loud, may need to purchase remote horns. When purchasing a remote unit (STI-6403 or STI-6404) you will need to periodically test the connections to make sure audibles function at a sound level to alert staff. Maximum of three remote alarms may be used in parallel.

7. Turn unit off with the key to silence alarm.
8. Apply optional label if desired.

Installation Instructions

1. Set switches on circuit board to desired alarm settings (Fig. 1).
2. If using external power source, use Class II UL Listed 12-24VDC supply. If not using 9V battery, be sure switch 6 is in “ON” position before connecting any power. Refer to page 4 figure 1.
3. Mount main unit on or next to the door using hardware provided. Reed switch may be located in one of four internal positions or route the reed switch through the slot in the bottom of the cover as shown in Fig. 3
4. Mount magnet using hardware provided. Magnet must be within ¾” of the reed switch when door is closed. Please refer to figures 8, 9 and 10 for other mounting options. Note: When mounting on metal doors or door frame, use plastic spacers provided.
5. If installing STI-6402, STI-6403, STI-6404 or STI-6405 continue to page 6.
6. Replace cover by sliding flanges on inside of cover into slots on base, snap closed and replace the tamper screw.

STI-6402 Double Door Install Notes

1.  If not using extra reed switch, leave jumper wire across terminals RS2 on terminal block.
2. STI provides 1 internal reed switch with approx. 14” wire and 1 reed switch with approx. 72” wire (cut wire to desired length).
3. First reed switch is connected to RS1. Remove jumper and connect second in RS2 (Fig. 4). Refer to Fig. 1 for additional details

*Note : Alarm will sound when either door is opened.

STI-6403 Remote Horn Install Notes

1. Remove cover.
2. Move relay function (switch 8) to “ON” (see page 4).
3. Connect two conductor wire (14-24 AWG) from main unit terminal block pins COM and NO to remote horn unit terminal block (wire not provided). Units can be set up to 300 ft. apart. Not polarity sensitive (refer to Fig. 1 and Fig. 5 for details).
4. Connect internal battery.
5. Mount similar to main unit with #8 x 1 in. screws and anchors if necessary.
6. Replace cover and screws.
7. Turn key switch to ON position.

• Note : The ON/OFF key position is opposite from 6400 main unit. Remote horn sounds when main unit alarm is activated.

STI-6404 Double Door with Remote Horn Install Notes
The STI-6404 is a combination unit for double doors with a remote horn. Reference the installation instructions for the main unit, the STI-6402 and the STI-6403 for complete installation.

STI-6405 Exit Stopper with Momentary Reset

The STI-6405 uses a momentary switch. After initial installation, unit is always on and you do not have to remember to turn it on when you leave a protected area. This model also eliminates having to remember to re-arm it because it is never off.
When the alarm is triggered, to silence the alarm, insert the key and turn completely to the “RESET” position and hold for 2 seconds, then release. The switch will spring back to its original position and push the key out. To turn the unit off, supply power must be removed.
