Smoke detectors and alarm system control panels have specifications for allowable loop resistance. Consult the control panel manufacturer’s specifications for the total loop resistance allowed for the control panel being used before wiring the detector loops.

Begin electrical connections by stripping about 38insula- tion from the end of the wire. Then, slide the bare end of the wire under the clamping plate and tighten the clamping plate screw. A wiring diagram for a typical 2-wire detector system is shown in Figure 3.

NOTE: Break the wire at each terminal to ensure that the connections are supervised. Do NOT loop the wire under the terminals.

System Sensor smoke detectors are marked with a compat- ibility identifier located as the last digit of a five digit code stamped on the back of the product. Connect detectors only to compatible control units as indicated in System Sensor’s compatibility chart which contains a current list of UL-listed control units and detectors. A copy of this list is available from System Sensor upon request.

Tamper-resistant Feature

This detector includes a tamper-resistant feature that effec- tively prevents removal of the detector without the use of a tool. To make the detector tamper-resistant, break off

the smaller tab at the scribed line on the tamper resistant tab, on the detector mounting bracket (see Figure 2), then install the detector. To remove the detector from the bracket once it has been made tamper resistant, use a small screw-

Each 1400 detector is supplied with a mounting bracket kit that permits the detector to be mounted:

1.Directly to a 312 inch or 4 inch octagonal, 112 inch deep electrical box, or

2.To a 4 inch square electrical box by using a plaster ring with the supplied mounting bracket kit.

Installation Wiring Guidelines

All wiring must be installed in compliance with the National Electrical Code and all applicable local codes and any special requirements of the authority having jurisdic- tion, using the proper wire size. The conductors used to connect smoke detectors to control panels and accessory devices should be color-coded to reduce the likelihood of wiring errors. Improper connections can prevent a system from responding properly in the event of a fire.

For signal wiring (the wiring between interconnected detectors), it is recommended that the wire be no smaller than AWG 18. However, the screws and clamping plate can accommodate wire sizes up to AWG 12. The use of twisted pair wiring for the power (+ and –) loop is recommended to minimize the effects of electrical interference.

Installation

WARNING

Disconnect the power to the alarm system control unit before installing detectors.

1.Wire the detector following the installation guidelines.

2.Line up arrows on the detector with the arrows on the mounting bracket.

3.Rotate the detector clockwise until it clicks into place.

4.After all detectors have been installed, apply power to the control unit.

5.Test the detector as described under TESTING.

6.Reset the detector at the system control panel.

7.Notify the proper authorities that the system is in opera- tion.

1400 specifications

The System Sensor 1400 series is an advanced line of smoke detectors designed to enhance safety in commercial and industrial settings. Known for its reliability and precision, the 1400 series employs cutting-edge technologies to ensure early detection of smoke and fire, thus providing crucial time for evacuation and response.

One of the main features of the System Sensor 1400 is its dual-sensor technology, which combines both photoelectric and ionization detection methods. This dual approach allows the detector to identify a wide range of smoke particles generated from various types of fires, from fast-flaming fires to smoldering ones. This versatility significantly reduces the chances of false alarms while maintaining a high level of sensitivity.

Another key technological advancement in the 1400 series is its built-in communication capabilities. The detectors can be integrated into larger fire alarm systems, allowing for remote monitoring and real-time alerts. This integration is facilitated by the use of an advanced communication protocol that enables quick data transmission and reduces response times in emergencies.

The System Sensor 1400 series also features a robust design that ensures durability and reliability. Constructed from high-quality materials, these detectors are resistant to environmental factors such as humidity and temperature fluctuations. This makes them suitable for a variety of settings, including warehouses, manufacturing plants, and commercial buildings.

In addition, the 1400 series incorporates a user-friendly interface that simplifies installation and maintenance. The detectors are equipped with LED indicators that provide visual alerts for operational status, including power, alarm, and trouble signals. This allows maintenance personnel to quickly assess the detector’s functionality and perform necessary checks or replacements.

Ease of installation is further enhanced by the use of a universal mounting bracket, which simplifies the setup process and reduces downtime. The series is also designed to accommodate various power options, including battery backup, ensuring continued operation even during power outages.

In conclusion, the System Sensor 1400 series stands out as a premier choice for smoke detection in commercial and industrial applications. Its combination of dual-sensor technology, robust design, seamless integration capabilities, and user-friendly features makes it a reliable solution for enhancing fire safety and protection in any environment.
