Before Installing

Please thoroughly read the system wiring and installation manuals, and manual I56-407, Guide for Proper Use of Sys- tem Smoke Detectors, which provides detailed information on detector spacing, placement, zoning, and special appli- cations. Copies of these manuals are available at no charge from System Sensor. (For installation in Canada, refer to CAN/ULC-S524, Standard for the Installation for Fire Alarm Systems and CEC Part 1, Sec. 32.)

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

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

General Information

Form C latching relay contacts are included for the control of an auxiliary function. The relay operates 12 seconds (nominally) after activation of the sensor head remote an- nunciator output.

Mounting

The detector base mounts directly to 31/2- and 4-inch oc- tagon and 4-inch square boxes, with or without a plaster ring.

To mount, remove the decorative ring by rotating it in ei- ther direction to unhook the snaps. Then, separate the ring from the base. Install the base on the box, using the screws supplied with the junction box and the appropriate slots in the base. Replace the decorative ring on the base and ro- tate it in either direction until the ring snaps in place (see Figure 1).
