Before Installing

Please thoroughly read the System Sensor manual A05- 1003, Applications Guide for System Smoke Detectors, which provides detailed information on detector spacing, placement, zoning, wiring, and special applications. Copies of this manual are available from System Sensor.

NOTICE: This manual should be left with the owner/user of this equipment.

IMPORTANT: The detector used with this base must be tested and maintained regularly following NFPA 72 require- ments. The detector used with this base should be cleaned at least once a year.

General Description

The 2151 low-profile photoelectronic detector uses a state- of-the-art optical sensing chamber. This detector is designed to provide open area protection and to be used with com- patible UL listed control panels only. The capability of plug- ging this detector into a variety of special bases makes it more versatile than equivalent direct-wired models.

Two LEDs on each detector provide local 360° visible alarm indication. They flash every ten seconds indicating that power is applied and the detector is working properly. The LEDs latch on in alarm. Remote LED annunciator capability is standard and may be implemented through an optional accessory RA400Z. The alarm can be reset only by a momentary power interruption. This detector may be tested by activating the internal reed switch with a magnet.

Base Selection And Wiring Guide

Refer to the installation instructions for the Plug-in Detector Bases for base selection and wiring instructions. System Sensor has a variety of detector bases available for

this smoke detector, including 2-wire applications with and without relays and/or current limiting resistors, 4-wire and 120VAC applications.

All bases are provided with screw terminals for power, ground, remote annunciator connections and relay contact connections, if applicable. The electrical ratings for each detector-base combination are also included in the base installation instructions.

Installation

NOTE: All wiring must conform to applicable local codes, ordinances, and regulations.

NOTE: Verify that all detector bases are installed, that the initiating-device circuits have been tested, and that the wiring is correct. (Refer to detector base manual for testing procedure.)

WARNING

Remove power from initiating-device circuits before install- ing detectors.

1.Install detectors:

a.Place the detector into the detector base.

b.Turn the detector clockwise until the detector drops into place.

c.Continue turning detector clockwise to lock it in place.

2.Tamper Resistance: The detector bases can be made tam- per resistant. When capability is enabled, detectors can- not be removed from the base without the use of a tool. See the detector base installation manual of the detector base for details in using this capability.

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