  • General
  • Feature
  • Specification
Isolator bases prevent an entire communications loop from being disabled when a short circuit occurs. They accomplish this by isolating that part of the loop containing the short from the remainder of the circuit. These bases also automatically restore the entire loop when the cause of the short circuit is corrected. In general, up to 25 addressable devices may be isolated between isolator bases. MOUNTING The detector base mounts directly to 31⁄2- and 4-inch octagon and 4-inch square boxes, with or without a plaster ring. To mount, remove the decorative ring by rotating it in either 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 rotate it in either direction until the ring snaps in place (see Figure 1).

Specification

Base Diameter: 6.1˝ (155 mm)

Base Height: 1.2˝ (31 mm)

Mounting: 4˝ square box with or without plaster ring,

Minimum Depth - 1.5˝ (38 mm) 4˝ octagon box,

Minimum Depth - 1.5˝ (38 mm) 3 1⁄2˝ octagon box,

Minimum Depth - 1.5˝ (38mm)

Operating Temperature Range: 14°F to 140°F (–10°C to 60°C)
NOTE: Do not install in locations where normal ambient temperature extends beyond 32°F to 120°F (0°C to 49°C)

Operating Humidity Range: 10% to 93% Relative Humidity Non-condensing

Electrical Ratings
Operating Voltage: 15 to 32 VDC Standby Current: 450µA Maximum

Alarm Current: 5mA Maximum Relay Contact Rating: 2A at 30VDC/0.5A @ 125VAC (Resistive); 1A @ 30VDC/0.25A @ 125VAC (Inductive)

FEATURE NOTE:

Do not use the tamper-resist feature if the removal tool is to be used.

This detector base includes a tamper-resist feature that prevents its removal from the base without the use of a tool. To activate this feature, break the tab from the detector base as shown in Fig- ure 4A. Then, install the detector.

To remove the detector from the base once the tamper-resist feature has been activated, insert a small-bladed screwdriver into the slot in the side of the base and push the plastic lever away from the detector head (see Figure 4B).

This allows the detector to be rotated counterclockwise for removal. NOTE: Head removal after the tamper-resist feature has been activated re- quires removal of the decorative ring.

The tamper-resist feature can be defeated by breaking and removing the plastic lever from the base. However, this prevents the feature from being used again.
