General Information Before installing detectors, please thoroughly read these installation instructions. For detailed information on detector spacing, placement, zoning, wiring, and special applications refer to current edition of the NFPA 72 National Fire Alarm Signaling Code. NOTICE: Do not discard this manual. Manual should be left with the owner/user of this equipment. IMPORTANT: This detector must be tested and maintained regularly following NFPA requirements. Test detector operation weekly.
General Description: The Model SD4-SS photocell electronic smoke detector with built-in wireless transmitter is intended for use with the Silent Call® Mini receiver to form an alerting system. The transmitter will send alarm condition messages to the system’s receiver. The SD4-SS wireless transmitter operation is to be used only with Silent Call® Signature Series Receivers. The transmitted signal incorporates a digital addressable coding system that is preset at the manufacturer.
This includes cleaning, maintenance or screen replacement. The Model SD4-SS contains a piezoelectric horn which generates the ANSI S3.41 temporal pattern in an alarm condition. During an alarm condition, pressing the detector’s test switch will silence the piezoelectric horn for 5 minutes. The built-in Drift Compensation algorithm automatically maintains the sensitivity of the detector.
Table 1: Detector LED Modes Green LED Red LED Piezoelectric Horn Power-up Blinks every 5 sec Blinks every 5 sec Off Normal (Standby) Blinks every 10 sec Off Off Out of Sensitivity Off Blinks every 5 sec Off Smoke Alarm Off Blinks every 1 sec Temporal Pattern Low Battery Off Blinks every 45 sec Chirp every 45 sec after LED blinks for 7 days During initial power-up, the red and green LEDs will blink synchronously once every 5 seconds.
functioning normally within its listed sensitivity range, the green LED blinks once every 10 seconds. If the detector is in need of maintenance because its sensitivity has shifted outside the listed limits, the red LED blinks once every 5 seconds. When the alarm has been activated by smoke, the red LED blinks every 1 second. The LED indication must not be used in place of the tests specified under Testing. If the detector senses a low battery condition, the red LED blinks once every 45 seconds.
Battery Life Expectancy: Replace the battery once a year or immediately when the low battery indicator starts to blink and the horn begins to chirp. Battery Installation and Replacement: To replace the battery: 1. Remove the detector from its mounting base by twisting the detector counterclockwise. Remove the battery and dispose of it properly. 2. To ensure proper power-down sequence, wait a minimum of 20 seconds before installing new battery. 3.

Recommended Locations for Smoke Detectors: The National Fire Protection Agency (NFPA) recommends one smoke detector on every floor, in every sleeping area, and in every bedroom. In new construction, the smoke detectors must be AC powered and interconnected. For additional coverage, it is recommended that you install a smoke detector in all rooms, halls, storage areas, finished attics, and basements where temperatures normally remain between 4.4°C to 37.8°C.
• cm) from the ceiling. see figure 1. Put a smoke detector at both ends of a bedroom hallway if the hallway is more than 40 feet (12 meters) long.
Dead Air Space Best in center of ceiling No closer than 4 inch (10 cm) from side wall Mount on wall at least 4 inch (10 cm) from ceiling No more than 6 inches (15 cm) from ceiling Best location Acceptable location Figure 1.2: Recommended smoke detector mounting locations.
• In rooms with sloped, peaked, or gabled ceilings, mount detectors within 3 feet (0.9 meters) measured horizontally from the highest point of the ceiling. See figure 2. Horizontal distance from peak 3 feet (0.9 m) Figure 2: Recommended smoke detector location in rooms with sloped, gabled, or peaked ceilings.
Where Smoke Detectors Should Not Be Located: Nuisance alarms are caused by placing detectors where they will not operate properly. To avoid nuisance alarms, do not place detectors: • In or near areas where combustion particles are normally present such as kitchens, in garages where there are particles of combustion from vehicle exhausts, near furnaces, hot water heaters, or gas space heaters.
Air Flow Air Return Bath Stove Bedroom Kitchen Correct Incorrect Bedroom Living Room Figure 3: Recommended smoke detector locations to avoid air streams with combustion particles.
• In damp or very humid areas, or next to bathrooms with showers. The moisture in humid air can enter the sensing chamber as water vapor, and will cool and condense into droplets that cause a nuisance alarm. Install detectors at least 5 feet (1.5 meters) away from bathrooms. • In very dusty or dirty areas. Dust and dirt can build up on the detector sensing chamber and make it overly sensitive, or can block openings to the sensing chamber and keep the detector from sensing smoke.
• Near florescent light fixtures. Electrical “noise” from nearby florescent light fixtures may cause a nuisance alarm. Install detectors at least 10 feet (3 meters) away from such light fixtures. Limitations of Smoke Alarms • Smoke detectors will not work without power. Battery operated detectors will not work without batteries, with dead batteries, or if the batteries are not put in properly.
• • • The horn in your detector meets or exceeds current audibility requirements of Underwriters Laboratories. However, if the detector is located outside a bedroom, it may not wake a sound sleeper, especially if the bedroom door is closed or only partly open. If the detector is located on a different level of the residence than the bedrooms, it is even less likely to wake up people sleeping in the bedrooms. All types of smoke detectors have limitations.
Test Switch Green LED Red LED Figure 4: Silent Call Model #SD4-SS Wireless Smoke Detector Transmitter Setting SD4-SS Wireless Smoke detector will be addressed at manufacturer to Code B, Code D or Code H. Detector will be labeled with preset address. To change address due to possible cross talk between like systems. Access the Dip Switch using a Torx T10 Screwdriver. Silent Call receivers can monitor/supervise up three different address selections. Battery must be reset for new address to resister.
Mounting First, determine the best location for the smoke detector, one that provides a strong wireless transmission path and proper smoke detection. A GOOD TRANSMISSION PATH MUST BE ESTABLISHED FROM THE PROPOSED MOUNTING LOCATION BEFORE PERMANENTLY INSTALLING THE DETECTOR. To check, perform the test described in the TESTING SIGNAL STRENGTH section of this manual. To mount the detector, perform the following steps: 1.
Figure 5: Mount Detector Across Ceiling Panel Support. DO NOT attach the detector to removable ceiling panels. Attach the detector across panel support as shown in Figure 5. Dust Covers are an effective way to limit the entry of dust into the smoke detector sensing chamber during construction. However, they may not completely prevent airborne dust particles from entering the detector. Therefore, it is recommended that the detectors be removed before beginning construction or other dust producing activity.
Testing the Sensor Detectors must be tested after installation and following periodic maintenance. The Model #SD4-SS may be tested as follows: A. Test Switch 1. A recessed test switch is located on the detector housing (see Figure 6). 2. Push and hold the recessed test switch for a minimum of 5 seconds. Use a small screwdriver or Allen key with maximum diameter of 0.18 inch (the detector will trigger and then the smoke detector will go into alarm thus sending a transmitting signal to the receiver.

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. Canned aerosol is also an accepted method.
Testing Signal Strength A test should be performed before installation to determine a strong communication path with the receiver and after installation is complete. Also the owner/user should test the unit at least weekly. Testing Programming A test should be performed before installation to ensure the detector transmitter address is properly programmed to the receiver, and are operational as a system.
Maintenance NOTE: Power must be removed from the detector before performing maintenance of any kind by removing the detector’s battery. 1. To ensure proper power-down sequence, battery must be removed from detector for a minimum of 20 seconds before servicing. 2. Vacuum the cover or use canned air to remove any dust or debris. 3. Using a vacuum or canned air spray carefully clean any dust or debris From Smoke Detector Cover. 4. Reinstall the detector and test. (see the Testing section).
What to do in case of fire • Don’t panic; stay calm. Follow your family escape plan. • Get of the house as quickly as possible.
